Abstract
1,040,868. Perforating apparatus: INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 5, 1965 [Sept. 10, 1964], No. 33583/65. Heading B4B. Perforating mechanism for a web 12 of sheet material comprises a pair of feed roller assemblies A, B, assembly A comprising a feed roller 13 and back-up rollers 16 free to turn independently of roller 13, and assembly B comprising a feed roller 14, bearer rollers 20, tool units 21, toolholders 22 and perforating tools 23, each roller 16 being mounted on its bearing through the intermediary of an elastic sleeve so that when the feed rollers 13, 14 are adjusted towards or away from each other, the rolls 16 remain in contact with the rolls 20.
