Title:
CONTINUOUS WEB INPUT GUILLOTINE CUTTER
Document Type and Number:
WIPO Patent Application WO2002016243
Kind Code:
A3
Abstract:
A buckle gap (G) is defined by first and second web guide assemblies (18, 20) upstream of the guillotine knife (38), so that a controlled buckle can form upstream of the knife (38) when the web is stopped as a part of the knife downstroke. The buckle gap (G) is defined at least in part by an adjustable guide (18, 20) so that a controlled area for web buckling can be defined to take up an appropriate amount of web material during the cutting portion of the cycle. After the cutting operation, once the knife (38) has cleared the anvil (60), the web is released to be fed past the knife (38). To ensure feed of the accumulated buckle of web material, pull rolls (40) are provided to pull the web forward to substantially remove the buckle before the next cut cycle.
