Sheet feed control in sheet processing machine involves temporarily altering duration of transport mechanism idle phase to set desired time of incidence of sheet at machine

摘要

The method involves the use of a transport mechanism that performs a cyclical movement sequence synchronized with the machine's operating cycle and containing a sheet transport phase and an idle phase. The duration of the idle phase can be temporarily altered to set a desired time of incidence of a sheet at the machine. The variation can be maintained over several working cycles.
