ANORDNING VID MASKIN FOR EMBALLERING AV FOREMAL I PLAST

摘要

The machining unit (10) is fitted between the cutting and welding unit (1) on the one hand, and the oven unit (2) on the other hand. It is to process the plastic sheets (6,7) so that they stick together along the unwelded sides. Warm air in the oven unit (1) is also prevented from coming between the plastic sheets before adhesion has occurred. The appearance of large holes in the plastic after heat shrinkage, and other damage and deteriorations involving the packing material when the packed object is handled, are avoided.
