Abstract
A separator for a sheet stacker having a support for receiving a stack of sheets on a stack conveyor. Another conveyor brings a stream of sheets to the support, and a sheet counter counts the sheets and a stack separator plate is controlled by the counter and interrupts the stream when a certain number of sheets have passed into the stack. Drive mechanism connects to the separator plate and the stack conveyor for alternately driving them and thereby separating out a stack of sheets. The separator plate is automatically operated and is under the control of a fluid cylinder.
