Abstract

557,681. Perforating sheet material. UNITED WIRE WORKS, Ltd., and EWEN I. E. Dec. 9, 1942. No. 17512. [Class 31 (ii)] [Also in Group XXII] Large sheets of non-metallic material to be punched or provided with groups of perforations are mounted in a machine to be punched area by area. The material is supported by rolls 3, 4, mounted in carriages 9 one at each end of each roll and traversable on rails 10, and extends at 7 over a work bed 8, the punches being carried by a head 11 reciprocated by connecting rods 12 and eccentrics 13 on a shaft worm driven at 16 from the shaft of a motor 18. Successive areas are brought over the work bed by winding and unwinding from the rolls and by traversing the carriages on the rails. A strip may be treated either by traversing the carriages or by winding, further strips being exposed by winding or traversing respectively.
