Abstract (en)
[origin: DE4439224A1] A device (10, 10a) for processing a web of a foil (13) incorporating bubbles (11) has cut-off blades (18 to 20) and perforators (24, 25). The cut-off blades (18 to 20) are arranged on a cutting roll (15, 15a) co-operating with a pressure roll (30, 30a). The invention proposes the integration of the perforators (24, 25) into the cut-off roll (15, 15a). This simplifies the construction of the device (10, 10a) and the packaging strips (12) cut out of the foil web (13) are always centrally perforated.
