Tension Control System
The NIRECO Tension Control System automatically controls tension during manufacturing and
various treatment processes of paper, foil, film, rubber, fabric, and so on.
INTRODUCTION
When a web of these materials is unwound or rewound the web
tension varies as the roll diameter of the material changes. Web
tension must be maintained at a constant level to prevent wrinkles,
sags, changes in width or thickness, or breakage of the web. In
printing processes, variable tension causes a paper web to stretch
or shrink, causing sudden register errors. This problem
necessitates tension control.
Tension sensors are mounted at both ends of a sensor roll.
The tension controller can be operated simply using a stable
proportional + integral action with a constant loop-gain circuit.
This configuration provides both responsivity and stability
regardless of roll diameter.
The actuators include both an electromagnetic brake and a
pneumatic brake for use when unwinding. The electromagnetic
brake can be connected directly from the controller but the
pneumatic brake must be used with an electro-pneumatic
converter. Winding can be achieved using many systems,
including an electromagnetic or pneumatic clutch, and
electromagnetic coupling motor or a torque motor. Intermediate
tension control can also be handled where necessary.
About Nireco Tension Controllers
Suppression of Hunting via Constant Loop Gain Circuit
Instability is a frequent problem with tension control. The main source of this instability is the fact that in order
to set the tension, it is necessary to change the brake torque, which is what is manipulated in order to control
tension; but if too much leeway is given in brake selection, and a high-capacity brake is selected, then the
output at small coil diameters could fall below the range of safe control. In general, the gain setting is
constant, and has no relation to coil diameter. Thus when the coil is small, there is a tendency for the loop
gain to increase, and for instability to result.
Nireco reduces control instability (hunting) by using a tension controller with a constant loop-gain circuit that
eliminates changes in loop gain due to changes in coil diameter.
Increased Stability through Proportion + Integral Calculation
There is some distance between the rewinding reel and tension sensor, and a certain amount of time to
transmit tension waves between them is unavoidable. In other words, there is a slight but real amount of
waste, and in addition, noise is generated in relation to the coil rpm. Consequently, stable control using
integral (I) analysis alone is not feasible. Additionally, brake input changes in accordance with coil diameter,
and so the offset with proportional (P) calculation alone is too large to use. Nireco tension controllers
therefore employ Proportion + Integral (PI) calculation for stable tension control.

FEATURES
Constant loop-gain circuit gives superio responsivity
and stability
Control circuit calculations are carried out by both
proportional and integral operations to give rapid, precise
responses. Exponential operations are used to maintain
a constant loop gain regardless of variations in diameter.
Therefore loop gain is always maintained at the right
level, with high responsivity but no hunting. This system
is extraordinarily effective when used with splicers, highspeed presses and in situations with high roll diameter
ratios.

Easy to use, simple to control
Given start and stop contacts, the system can be
controlled automatically. Anyone can operate it just by
setting a target tension value. A sequencer is built in that
gives an output value corresponding to the diameter

Tension indication available
In addition to total tension, tension for a single side can
also be sensed.

MB TENSION SENSOR
MB05, MB11, MB25, MB33, MB41
The MB Tension Sensor was designed to be used with a tension controller or tension meter.
It supports a wide range of products, with any tension range. The MB Tension Sensor has long
been a strong seller, since sales were launched 20 years ago.
FEATURES
Proven Track Record and Reliability
Without bearings or similar mechanical contacts, and
employing a non-contact detection method using a
differential transformer, the MB Tension Sensor is highly
responsive with low hysteresis. The compact size also
requires little space for installation.
Easy to Install
The MB 05, 11, and 25 can be installed at any angle.
Wide Selection of Sensors
1 Full range available, from low tension (50 N full
scale) to high tension (10,000 N full scale)
2 All sensors have intrinsically safe construction.
MB05
Overload Resistant
The durable construction provides resistance to
momentary overloads.

Tension Sensor
PRINCIPLE AND CONSTRUCTION
To measure the tension, attach a MB tension sensor to 3 rollers
arranged in a triangle (see figure at right).
The relation between the tension "T" and the load "F" is
expressed by the following equation.

Structure of MB Tension Sensor (this drawing shows model MB25)
The figure above shows the structure of the MB tension sensor.
When the web tension increases, the resultant force F of the
tension acts downward on the pillow block on which the roll is
mounted. Due to this load, a very small rotation occurs, starting
from the fulcrum O. Since this fulcrum has a spring action, the
rotary displacement is proportional to the resultant force F. This
displacement is very small at the roll, and reaches a maximum at
the core which is remotest from point O. This mechanical
displacement is converted into an electrical value proportional to
the displacement of the differential transformer.
Since the displacement due to deflection of the fulcrum is
proportional to the load, the electrical value produced is
proportional to the load, the electrical value produced is
substantially proportional to the tension ( ∝ load). Thus, the
fulcrum and differential transformer determine sensor
performance. Therefore, the fulcrum is machined by cutting, and
its material excels in spring action (hysteresis and strength), while
stress is at a sufficiently low value. The differential transformer
also has a high oscillation frequency, and the temperature
characteristics are excellent.

MG TENSION SENSOR
MG010, MG020, MG050, MG100, MG200
The MG Tension Sensor was designed to be used with a tension controller or tension meter. It
features compact and rigid construction, high accuracy, reduced temperature drift and high
response.
FEATURES
With excellent temperature characteristics, the compact
size saves space as well.
Additionally, non-contact detection using a differential
transformer yields improved precision.
PRINCIPLE AND CONSTRUCTION
MG Tension Sensor
When web tension is applied to the MG tension sensor, the
movable core of the differential transformer moves about the
spring fulcrum 0. That change in core position causes the
differential transformer to vary the electrical signal.
Figure 1 shows the structure of the MG Tension Sensor. When
web tension (T) is applied to the sensor roller, load (F) of tension
acts downward on the load bearing plate. Due to this load, the
load bearing plate rotates minutely about the fulcrum point 0. The
torque generated bends the spring fulcrum.
This small displacement of the load bearing plate reaches a
maximum at the opposite side of fulcrum point 0, where the core
of the differential transformer is installed. The mechanical
displacement of the core is converted into an electrical signal by
the differential transformer, using the change in mutual
inductance. The signal is sent to a tension controller or a tension
meter. The relationship between tension (T) and load (F) in the
structure, as shown in Figure at right is expressed by the
following equation.

MC05, MC20, MC30
The MC tension sensor is a force converter designed especially for tension controllers or
tension meters. It is a high-precision instrument suited to high-speed lines.
FEATURES
High spring-steel characteristics provide a high
resonance point, ideal for a high-speed line.
Load-displacement is extremely small, making it effective
for single-sided plastering of thin-web lines (e.g. film and
aluminum foil).
Use of a simple mono-block construction provides
excellent precision, linearity, and hysteresis.

FUNCTION
1 Tension Indicator
3 Sequence Operation
This section amplifies the signals from the No. 1 and No. 2
sensors of the MB Tension Sensor and adds them for display at
the tension indicator. The amplified signals are also then fed to
the PI control section.
This operation applies proper timing to the controller operation by
START and STOP timers. The start timer is used to set the proper
waiting time (variable between 0 to 20 seconds) on start for the
machine operation to enter into automatic operation. The stop
timer is used to determine the duration of the stopping break
(variable between 0 to 20 seconds) in proportion to the coil
diameter on stopping of the machine.
2 PI Control Section and Exponential Operation
The signal output from the adder section is compared with the
"set" signal. If there is a deviation between these two signals, the
PI section performs operations to reduce the deviation. These
operations are both P (proportional) and I (integral). Integral
action eliminates "offset" (Target value and detected value should
not match), providing the exceptional stability of the system. The
function of exponential operation is to maintain the loop gain
constant, regardless of changes in web roll diameter. Therefore,
better response and stability can be maintained.
4 Current Amplifier Section
When the actuator used is an electromagnetic clutch or brake, the
output signal current is amplified (0–4A)before it is transmitted.
When a pneumatic brake or clutch is used, the output of 4–20mA
is converted into an electro-pneumatic air pressure of amplified
flow for transmission to the clutch or brake.

Brake & Clutch
POWDER BRAKE NBS-2.5, NBS-5, NBS-10
Powder-type electromagnetic brakes have been developed for use in the tension control of
webs. By using magnetic powder as the medium for the transmission of torque and by
regulating the coil's excitation current, it has been possible high performance, and an extended
service life.
GENERAL
The brake's current-to-torque characteristic enables
transmission torque to be generated from a small
excitation current and, furthermore, this generated torque
has an excellent linearity. Accordingly, the control of
torque is possible over a large operating range.
This type of brake does not generate the type of friction
dust common with friction-plate brakes. Levels of contact
noise are low; consequently, this product is highly
suitable for silent-operation applications.
Since deviations in input speed cause no resultant
fluctuations in transmission torque, tension control for
contact-slip operations can be easily achieved.

●Allowable Shaft-End Load

1 Current-to-Torque Characteristic
Torque can be generated using a small amount of excitation
current and the corresponding linearity extends over a large
operation range.
The excitation Current-to-Torque characteristic
2 Torque Startup and Torque Annihilation Characteristics
When an excitation voltage is applied to the coil, the excitation
current which passes through that coil will increase in accordance
with its tim constant.
Furthermore, torque will be generated in the brake during periods
of inactibity due to these increases in excitation current, and this
torqu will ultimately reach saturation level. The coressponding
torque startup time is represented by Tr.
When the coil's excitation voltage is turned off, the corresponding
electrical discharge will progress in accordance with the coil's
time constant and the excitation current will reduce to zero. The
brake torque will also drop as a result of these factors, and the
time Tf at which it reaches 10% of the saturation torque is
referred to as the "torque annihilation time."
Torque
Freewheel torque is generated when an excitation current is not
flowing, and the factors which caouse this phenomenon are
considered to be mechanical-type friction at locations such as
bearing seals and also residual magnetism. The freewheel torque
in NBS brakes is 1% of the rated torque or lower.

2 Speed-to-Torque Characteristic
As long as the excitation current is maintained at a constant
setting, variations in input speed will not affect the brake's torque
(this is referred to as the "constant torque characteristic").

Current
Accordingly, this type of brake is ideally suited to situations
where the web is fed at a constant line speed from an unwing coil
operating, and where the coil diameter reduces over time, thus
causing the brake's input speed to be increased.
Since variations in the input speed do not lead to correspondeing
changes in brake torque, tension control can be achieved with a
high degree of both ease and stability.

Brake & Clutch
CHARACTERISTICS
When continuous operation is carried out, heat which is generated
as a result of slipping causes the temperature of the brake unit to
increase. If this type of temperature increase is not maintained
within a specific range during operation, performance can be
impaired or, in certain cases, a breakdown may occur. the slip
factor is used to define this permissible temperature range. Note,
however, that even if the brake is operating within the permissible
slip-factor range, continued operation will not be possible if the
rated torque is exceeded.
When a brake is being selected, the following items of data
corresponding to machine-operationg conditions will be required.
Line speed
: V max, V min, (m/min)
Coil diameter : D max, D min, (m)
Tension
Permissible slip torque (Nm)
Permissible slip torque characteristic
: Tmax, T min, (N)
■ Example of selection of a brake for unwinding:
Line speed

: V min = 30 (m/min)
Coil diameter : D max = 0.80 (m)
: D min = 0.11 (m)
Tension
Speed (Nm)
: T max = 140 (N)
: T min = 60 (N)
3 Slip Factor
Slip factor is the product of speed and torque, and consequently,
this value will decrease as the speed decreases.
In situations where an unwind coil is being used, the
corresponding calculations should be performed using the working
torque which corresponds to the maximum line speed.
1 Speed
The permissible range of imput speeds for the brake is 10 to 1800
rpm. It is important to confirm that equipment in question is
actually operating.

4 Brake Selection
A maximum working torque of 56Nm dictates that the NBS-10 is
most suited for application. It is recommended that the maximum
working torque be at least 50% of the brake's rated torque.
The slip factor is 230W at an input speed of 40rpm, and, referring
to the graph of continuous slip-factor characteristics for the NBS10, It can be seen that a slip factor of approximately 260W will
occur at 40rpm. Accordingly, the NBS-10 may be employed in
this situation.
5 Connecting the Unwind Coil and Brake via Gears
If it is desired to connect the brake to an unwind coil via gearing,
the corresponding gear ratio will be required during brake
selection.
■ Example of selection of a brake for unwinding

: V max = 70 (m/min)
● Brake selection
most suited for application. During the subsequent consideration
of slip factor, it can be seen that when the brake input speed is
56rpm, the slip factor is 179W.
Using the slip-factor characteristic for the NBS-05, it can be
determined that a slip factor of 204W will occur at 56rpm;
consequently, the NBS-05 may be employed in this situation.
■ Example of selection of a brake for unwinding
(Decelation of brake)

: T min = 30 (N)
: G2 /G1 = 2.0

Note: Refer to figure below

The above apply to the same formula as the previous example.

Using the slip-factor characteristic, it can be determined that a slip

This tension controller is equipped with a function which eliminates tension value changes due

GENERAL
This section describes the air-brake method of operation. The
controller's output signal is sent to the air brake of the rewinding
reel via EN40 (see Auto Booster Configuration drawing). When
splicing, a reel-change signal is sent to the controller and
switching valve, automatically initiating a sequence to switch the
controller output to the new reel, and at the same time bringing
the old reel to a fast halt by applying the halt brake via air
pressure from the pressure-relief valve. The torque level of the
new reel is uniquely set by the tension setting and initial rewind
diameter. Note that a bumpless circuit is employed for smooth
splicing.

The TDT1240 Dancer Roller-type Tension Controller varies the pressure in the compressed air
cylinder in proportion to the position of the center of the dancer roller.
GENERAL
The TDR 1240 features air-cylinder pressure that changes in
relation to the dancer roll position, and adjustable air-pressure
change gain. Conventionally, air-cylinder dancer-roll control
would use the same tension control regardless of the dancerroll position. The TDR 1240, however, allows the dancer roll's
return to center position to be sped up. This has a damper effect
on the air cylinder, allowing for more stable tension control.
As this absorbs sudden fluctuations in tension during paper
feed and the like, it is particularly well suited to lines that
operate intermittently.

exposed to damage.
Easy to operate
It is operated just by setting the roll radius and the web
thickness.
Stop output circuit incorporated
A stop output signal is generated when stopping an
unwinder. The reel is stopped without slackening the
web.
Applicable to various brakes/clutches
It is available with voltages of 0 to 10V and currents of 4

OPEN LOOP TENSION CONTROL SYSTEM
TCD050
The TCD050 s a controller for controlling the tension of a web at the unwinder or winder,
without using a tension sensor. The roll diameter is calculated by using signals from two
generators mounted on the winding/unwinding reel, and a control signal corresponding to the
change in the roll diameter is delivered.
GENERAL
The roll diameter can be measured
The roll diameter is indicated on the indicator while a
signal of 0 to 5 V is issued. The TCD050 can be used
for other applications such as external taper signals for a
closed-loop controller.
Not necessary to use gears
The roll diameter is calibrated internally. It is not
necessary to use gears between the measure roll and
the pulse generator.
The sequence control makes operation easy
Since a stop signal that is proportional to the roll
diameter is output when the line stops, the web is
prevented from slackening.
The re-start level allows smooth re-starting because the
stop level immediately before the line stops is stored. In
addition, the start level can be set manually with the
manual VR by resetting this stored stop level with the
reset contact.
Applicable to various brakes/clutches
The control output is available at a voltage of 0 to 10 V
and a current of 4 to 20 mA. Using them, the TCD050
can control an electromagnetic brake/clutch and an air
brake/clutch.
Taper tension can be controlled
In addition to the constant tension control, the taper
tension can be controlled.
Tension Controller TC050
Compact unit
This compact unit can be panel-mounted. It can be
easily installed in the control panel.
Non-contact detecting system
The non-contact detecting system allows the TCD050 to
measure the roll diameter without causing any damage.
In addition, it is not necessary to make a roll space for
attaching a sensor, which is required with other control
systems.
In the figure to the left, the tension value can be obtained
from the following formula (1).

2. A maximum roll diameter of more than 1500 mm is available.

*2 : For a measure roll diameter of 151 to 250 mm. In this case, the measure
roll is coupled directly to the encoder.
SEQUENCE CONTROL
The TCD050 automatically controls web tension using a
reset contact signal and a stop contact signal for the
machie. The sequence is as follows.
1. The reset (RESET) contact is made to reduce roll slip
at the same time when th machine starts, and the
output becomes the start level that has already been
set with the manual VR.
2. The output becomes the control level to control the
tension after the winding/unwinding reel has rotated
four turns.
3. The output becomes the stop level when the stop
(STOP) contact is made at the same time as the
machine stops.
4. The output becomes the level immediately before the
machine stops by turning off the stop contact after
the roll has stopped.
5. If you want to maintain that output during operation,
make the hold (HOLD) contact.

1. Refer to the bearing manufacturer's catalogs for fitting between the roller shaft and the bearings.
2. For ease of maintenance, make sure the CD tension sensor can be removed from outside the
machine frame.
3. If the rollers and bearings are expected to heat up, allow a margin for thermal expansion when
fitting the bearing.

Class-D grounding or better
Note:
1. Class-D (i.e., old class 3) grounding should be carried
out at the FG terminal.
2. FG* should be connected to the closest FG terminal
block (i.e., FG 1 to 6). (FG is connected internally)
3. MB and MG sensors are to be connected between
terminals 1 and 4, and between terminals 17 and 20.
MC and CD sensors are to be connected between
terminals 3 and 6, and between terminals 19 and 22.
Cables are to be connected to sensors with a standard
length of 5 m.
4. When just a single sensor is being used ( i.e., one-side
detecting, one-sensor fixed), terminals 3 and 9 are to
be shorted.
5. It is not possible to combine use of MB and MG sensors
with that of MC and CD sensors.
6. When connecting an external tension meter, be sure
to remove the shorting plate from between terminals
25 and 26 in advance.
7 .When connecting an L-load, make sure that a spark
killer is used.
8 .The numbers 0 to 30 are written on the signal terminal
in matte characters, but the controller uses 1 to 32.
Perform wiring in accordance with this wiring diagram
and the silk wiring diagram on the PCB in order to
prevent mistakes.

Note:
1. In case of reverse tension, swap the green and yellow
wires.
2. For one-sided detection, short circuit controller
terminals 5 and 6 together.
3. If the start signal is a hold signal, wires 17 and 18 to the
stop-side contacts are unnecessary (diagram below).
Wire as shown above if the signal is instantaneous.
Use the SEQ switch inside the controller to select
between the above cases.
In case of a 16

Start for ON,
stop for OFF
4. Start and stop contacts are both a-contacts which
should be independent for each controller.
5. Move the power supply voltage selection pin inside the
controller to 100V, 110V, 200V, 220V or 240V as
required.
6. Always earth terminal 28.
7. If the AC200V, 220V or 240V power supply is a motor
power supply with a large noise component, use
AC100V or 110V.
8. Parts marked "*" are optional.

Powder Brake NBS-5, NBS-10 Dwg. No. UC8945.0-EA
Installation precautions
• When the brake is being installed, care must be
taken to prevent the shaft from being exposed
to excess forces.
• If the brake's shaft is to be connected to other
shafts during use, flexible couplings must be
used; furthermore, the level of concentricity and
perpendicularity must be within the allowable
range for the couplings used.
• The lead wires and cables must be securely
coupled using closed connectors.
• The lead wires must be secured in such a way
that they cannot come into contact with rotating
components.
• The area surrounding the brake must be
checked to confirm that its ventilation holes will
not be blocked or obstruced.
• The brake must be oriented with the shaft in a
horizontal configuration.
• In situations such as where the brake is being
driven by a pulley, the allowable shaft-end load
requirements must be strictly observed.

DETERMINING BRAKE AND CLUTCH TYPE
Always use brakes and clutches with superior induced current, air pressure and torque properties.
Determine the ones to use according to continuous slip efficiency, maximum torque and maximum and minimum revolutions. As a general guideline, the ratio of maximum torque/minimum torque for a single brake and clutch should be less
than 20. Use multiple brakes or clutches if this ratio would be exceeded.
