Abstract
1295740 Slitting apparatus JOHN DUSENBERY CO Inc 14 July 1970 [28 April 1970] 34157/70 Heading B4B Foil slitting apparatus comprises a circular cutting knife 17, a circular backing disc 18, means mounting the knife 17 and disc 18 for rotation about a first axis normal to the plane of the disc 18, and means mounting the knife and disc for pivotal movement about a second axis normal to the first axis. The disc 18 has a frusto-conical surface portion against which the knife 17 is pressed so that its edge is offset from its general plane. As described, the knife 17, Fig. 5, is pressed against the edge portion of the disc 18 by a washer 21 and co-operates with a driven back-up knife 25. A resilient ring 27 in a groove in the disc 18 serves to minimize the tendency of the foil to wrinkle and causes the peripheral speed of the knife 17 to equal the linear speed of the foil. The knife and disc are carried by a shaft 20, Fig. 1, freely rotatable in a housing 28 fixed to a second housing 37 and lever 38. The housing 37 is mounted on a post upstanding from a slide plate 43 so as to be pivotable about an axis a. The assembly comprising the housings 28 and 37, and lever 38 is pivoted anti-clockwise by the piston 68 of a pneumatic cylinder 66 to urge the knife 17 axially against the knife 25, and the pivotal movement is limited by an adjustable stop screw 40. The slide plate 43 is mounted for sliding movement on a mounting bar. Rotation of a differential screw 56 threaded into a bracket 16 on the mounting bar causes the plate 43 to slide and thus enables the overlap between knives 17 and 25 to be adjusted.
