Laminator
Hennecke's laminators produce
optimum-quality sandwich elements with high-grade metal-facing surfaces.
Advantages
 |
Torsionally rigid design compatible for maximum foam pressures
|
|
High-precision manufacture ensuring completely plane and parallel operation of top
and bottom conveyor
|
|
The ground surface quality of the steel supporting plates ensure that no geometric
impressions will occur on the facings.
|
|
The conveyor plates have treated surfaces to eliminate virtually any "metal marking"
on facings without protective film (option)
|
|
|
Circulating-air temperature-control system
including air guides and all-round insulation
Advantages
|
Energy saving system because only the steel supporting plates are temperature-controlled |
|
High-precision and constant temperature control due to direct air heating of plates |
|
Also available as a two-circuit system so that different temperatures can be realised on
top and bottom conveyor |
|
Separate heating and cooling circuits to meet requirements of diverse raw material
systems and processing temperatures |
|
|
CONTIMAT side-sealing system
guides the facings and absorbs the lateral foaming pressure.
|
Width adjustment is realised by three-phase gear-motors fitted on both sides halfway down
the CONTIMAT line and a number of worm gear units that are interconnected by drive-shafts |
|
Frequency-controlled drive unit with integrated tensioning station for the sealing-block chain |
Advantages
|
Production changes, i.e. element widths and thicknesses, take very little time |
|
Plane-parallel adjustment of the right and left support structure |
|
Sealing chains are synchronised with the plate conveyors |
|
|
|
Cutting machine
The continuously produced element is
cut to the specified length about 10 - 15 m down-stream of the
CONTIMAT. Hennecke's patented cutting machine cuts "on the fly"
from left to right. It has a fine-toothed bandsaw blade to
ensure clean and precise cuts even with minimum panel lengths.
A special flash-trimming device also enhances the cut quality.
Advantages
|
Bandsaw blades have a long tool-life and ensure high-quality cuts with next to no flashing |
|
Cathodic protection at the sheet-metal edges |
|
Optimum cutting accuracy due to electronic length measurement with microprocessor-controlled
evaluation |
|
Rugged, high-quality design also ensures maximum angular precision |
|
Comes fully enclosed to provide optimum noise absorption and safety at work
|
Saw-blade turning device
Turns the saw blade by 90° (right and left)
Advantages
|
Cutting from both sides means that minimum panel lengths can be realised. |
|
|
Special-purpose saw
for lap-joint edges of roof elements
|
Bandsaw with integrated circular saw and 180° rotating device. |
Advantages
|
Length and overlap cuts are carried on in one step
(saves time and cost)
|
|
Cuts can be made at either end of the sandwich element |
|
Cuts can be made given different trapezoidal profile heights and element thicknesses |
