Abstract

1,086,596. Perforating &c. machines. TIMSONS (HOLDING) Ltd. July 11, 1966 [July 16, 19651, No. 30303/65. Heading B4B. A machine for perforating or notching a web w comprises a rotatable patrix 2 with which cooperates a roller or wheel 8 having an abrasive surface and driven at a higher speed than the patrix. The patrix tools 3 may be integral with the patrix or set in axial grooves therein. Alternatively, the patrix may consist of one or more radially extending arms, or pairs of such arms, which carries or carry the perforating or notching tools, the arm or arms being oscillated. In a modification, the abrasive surface is provided on an endless band (9, Fig. 2) extending over rollers (10, 11), one or both of which are driven.
