Abstract

1,141,834. Perforating apparatus. WINDMÍLLER & HOLSCHER. 9 March, 1966 [26 April, 1965], No. 10337/66. Heading B4B. Apparatus for transversely perforating a continuously-advanced plastics web 15, Fig. 1, comprises a perforating knife 3 having teeth 18, Fig. 3, which may be W-shaped, co-operating with corresponding recesses in a backing roller 13 and a stripper bar 6, which slides across one of the surfaces of the knife faces. During or before penetration of the web by the teeth the bar is moved towards the base of the knife. As the teeth are withdrawn from the web, the bar is moved away from the base of the knife, past at least part of each cutting edge provided by the teeth. As described, at least two knife-holders 1 are secured to a knife roller (not shown), and a retaining bar 2 is secured to the knife holders with a recess for the knife 3. The stripper bar 6 is slidable across the knife 3, is in a recess in a clamping bar 4 and has guide pins 8 with ends slidable in bores in the bar 4. The stripper bar is urged downwards by springs 9 as the perforating knife disengages the grooved roller. The pins and springs 8, 9 are provided in sets spaced along the clamping bar 4. The backing roller 13 has grooves provided by lands 14 and, after the stripper bar has stripped the perforated sheet it is returned against a stop face 11 by running up the lands 14 before beginning a fresh perforating cycle. To prevent damage to the lands the bar is made of e.g. light weight plastics with a slightly rounded outer edge.
