With this Unit you are able to produce so-called panorama boxes with a foil glued around the corner with a smooth bending edge and a punching out in a single working step.
Coming from the unwind unit the film will be delivered to the heating device.
The adjustable heating device heats the film in the creasing area to secure an optimal creasing quality of all kind of films. The heating device will be moved to the film stream by means of pneumatic cylinders while the machine is running. In case of machine stops the heating device will be moved back to avoid thermal damage of the film. The lateral setting of the heating devices can be set from outside of the machine by means of handles.
The heated film stream will be delivered to the creasing station afterwards. The creasing rollers can be set on and off during running of the machine from outside and run with the film over a hardened shaft. The hardened creasing rollers can be replaced; the corresponding creasing depth can be adjusted according to the foil thickness and use of the film. The lateral setting of the creasing devices can be set from outside of the machine by means of handles.
After the creasing station, the film will be delivered to the punching unit. Therefore the continuously running film will be stopped mechanically whilst a punching bar with the punching tools is carrying out the punch. During punching operation the foil movement is compensated by a swing which is mounted on the right and the left side of the punching bar. The punching unit is driven by a separate servo-motor.
As a standard this unit will effect 2 creases and 2 punches into the film stream. It may not be converted with same tooling depending on materials like PVC and PET. One more set of tools could be necessary due to the various materials to be converted.
