Abstract (en)
[origin: US6142463A] A lifting device for an automatic pile changing device of a sheet-processing machine, in particular for a sheet-fed offset printing machine with a non-stop feeder, having a main pile-carrying assembly and an auxiliary pile-carrying assembly which can be raised and lowered by means of a motor and an upstream drive unit. The invention allows simple and cost effective synchronization of the main pile-carrying assembly and of the auxiliary pile-carrying assembly within given tolerances. According to the invention, this is achieved by switching signals of equal duration determined by a common control unit coordinating two drive units. At least one of the drive units is assigned parameters that enable this synchronization.
