Abstract (en)

[origin: EP0309815A2] In a device for feeding sheets, aligned at front marks, to a sheet- processing machine, in which the sheet is conveyed by a driveable acceleration roll and a pressure roll which interacts cyclically with the latter, the pretensioning in the sheet, which is produced when the sheet strikes against stops of a sheet-transporting cylinder, can be infinitely adjusted. For this purpose, a cycle-determining control drum is provided, along whose axis of rotation there is a recess having an infinitely varying opening or switching angle. <IMAGE>
