Abstract

The large step feed mechanism grips a sheet and advances it while the sheet is uncoiled from the roll. When the sheet arrives at the perforating station (1) further clamping devices (4, 5) centre the sheet. These two clamping devices are fitted with feed mechanisms (6, 7) which perform feeding in small steps during the perforating operation. When the clamping devices (4, 5) become operative, the first clamping device (2) releases the sheet. Once perforating is finished clamping device (2) takes over again, while clamping devices (4, 5) release the sheet and clamping device in conjunction with feed mechanism transports the perforated sheet towards the shearing station.
