Specialties in Edgebanding
1. Lasertec
2. Softforming
3. Postorming
4. entry level CNC edgebanding
laserTec
1.
Using laserTec, the surface to
be glued is melted shortly
before contact between the
edge and workpiece
2.
The laser beam is deflected by
an oscillating mirror over the
whole width of the edge band
and melts the laser-active layer
3.
This is followed immediately by
pressing of the edge band onto
the workpiece

Occupational safety:
No special precautions needed due to certified laser protection class 1
(comparable with a laser pointer)
no potential for injury
All laser-relevant precautions are monitored, i.e. laser cannot be used without
all safety features in place
Alternating operation (e.g. conventional EVA and laserTec)
laser
can be carried out
without training as laser safety officer
Fundamental maintenance can be implemented after training at HOMAG
(e.g. exchange of protective glass)
Training generally recommended / necessary
Integrated extraction
Effects of using laserTec (1):
Elimination of glue system technology:
No glue selection
No determination of process parameters (weight by unit area, application
temperature)
No exchange/provision/maintenance of application units
No waiting times for heating up glue
No soiling of the pressure zone by glue
No granulate handling
No separating agent required
Effects of using laserTec (2):
Reduction of adjustment / disturbing variables impacting on the process:
e.g. change of glue type
Degree of soiling of the application unit (roller)
Reduced tool soiling in finish processing, resulting in:
Constant processing quality
Reduction of maintenance input for tools and machines
Reduction of scraping work due to elimination of glue residues
Increase of plant availability, reduced rejects quota and reliable repeat process
accuracy
Increased process reliability:
Glue type, quantity, distribution and colour prescribed by laser-active layer
Required laser energy clearly defined by laser-active layer (no excess energy input) no
gluing errors
Automatic setting of laser output by means of flexible edge sequence dep. on:
Workpiece thickness
Feed rate
Laser-active layer
Constant finish processing quality due to minimized tool soiling
Reduction of manual reworking
1. Perfect quality without compromises:
Invisible glue joint of 0,05 mm thickness
No residual glue after edgebanding
highest heat and moisture resistance (better than PU)
best bonding strength

2. Highest operation efficency:
No waiting time for the operator until operating temperature is reached
No glue color change necessary due to invisible glue joint
no resetting work required when changing color
no setting in respect of glue quantity and application temperature
no handling of different glue types
no possibilities for mistakes (e.g. wrong glue color)
Process simplification through reduction of process-determining
components
Highest machine usage due to less machine downtime for cleaning/
maintenance
Reduced finish cleaning work

3. More efficient use of resources, thus environmental
protection (i.e. green product):
Lower total energy requirement
Almost no energy and glue consumption without production result
Assured process parameters lower rejects quota
No glue vapours
No chemical substances for cleaning required

Laser technology - conclusion
...represents a quantum leap forward for furniture production
...generates uniqueness & competitiveness in product quality
...reduces requirements for operators capabilities
...optimizes resource efficiency and creates green products
...allows you to be innovative leader
...provides the assurance of more success

Softforming
What is softforming?
1.
A profile has to be trimmed to
the workpiece edge
2.
special edgebanding has to be
applied and softformed around
the edge of the workpiece
Therefore the glue is applied to
the edgeband and not to the
board
3.

Why softforming?
1.
allows creative edge design
2.
various material can be used
e.g special veneer, plastics
3.
possilbe inlay profiles
Principle of softforming / which units are needed?
For an inlay profile top or top/bottom you will need a „scoring and
trimming unit“ with a very precise tracing from top or top/bottom. You
have to trim the top or top/bottom of the panels in the same
thickness of the softforming edging material to guarantee a perfect
joint between the softforming material and the panel surface top or
top/bottom.

What units are needed?

2.

3.
special pressure zone
Pressure zone softforming
• Profile rollers or profile shoes for
top/bottom profile (each shoe or roller
spring-loaded)
• Rolling knife top and bottom (for inlay
profile top and bottom)
• 1 set of 6 non-driven pressure rollers for
straight profiles
• Manual height adjustment
• Manual lateral adjustment
• Manual rotation of set
• 6 straight rollers and space for max. 3
different profiles included (profile rollers or
profile shoes not included – by choice - )

Postforming
What is postforming?
1.
workpiece edge will be profiled
trimmed but the laminate will be
left
2.
after profiling the laminate
overhang will be bend around
the workpiece edge
3.
Post processing
Why postforming?
1.
only 1 glue joint, which can be
sealed e.g. by glue
2.
used for rooms with high
humidity like bathrooms or
labratories
3.
No edgeband necessary since
the laminate will be bend
around the material
Sequence
1.
scoring from top
2.
Trimming of the top material
and of the particle board with a
trimming unit top
3. Profiling of the particale board
Sequence
4.
Special trimming for the (later)
application of the hot melt
5.
Application of the hot melt with
a slit nozzle
6.
Application of hot melt glue on
the overhanging laminate (CPL
or HPL)
Sequence
7.
Application of PVAC-glue (white
glue) with nozzles on the
overhanging laminate (CPL or
HPL)
8.
Heating of the PVAC glue and
of the CPL/HPL laminate with
controlled heating bars.
Sequence
9.
Deforming and bending of the
CPL/HPL laminate within the
given radius, with combination
of a bending rod, steel and
rubber rollers.
10. Deforming and bending of the
CPL/HPL laminate within the
given radius, with combination
of a bending rod, steel and
rubber rollers.
Sequence
9.
Precise finish trimming of the
laminate for L-profiles. Cleaning
and polishing with the top
buffing unit
