<p>The machine has a pressing part formed as a suction housing (14) with a pressing edge (15) that is connected with a vacuum unit. The housing is axially moved from a standby position to a storing position during a cutting and storing process. An elastically compressible frame (19) made of rubber lies opposite to the pressing edge of the housing for evacuation and pressing of plastic foils on a base plate (7) parallel to a welding rod. The frame defines a space as a vacuum chamber while introducing and attaching the housing.</p> |
