Device for acting on sheets in a sheet delivery apparatus

摘要

The equipment is for a press printing sheets on one or both sides. he sheet-stretching mechanism (6) has a top surface in the plane in which adjacent sheet-conveyors (1, 2) work, also holders (7, 8) for printing on one or both sides. Its surface is flushed by an air cushion generated by adjacent jet nozzles (3). The latter can be in the adjacent conveyor surfaces. The latter can be exposed to low-pressure air, and the stretching mechanism can incorporate distortion areas (11, 12) opposite each other.
