Signature feeder and method including a variable speed separator disk

摘要

A signature feeder for delivering stacked signatures to a conveyer or gatherer includes a variable speed separator disk for separating signatures from the stacked signatures. The separator disk mechanically couples with a servomotor. The separator disk has a blade with a leading edge and a trailing edge. The servomotor accelerates the separator disk through the stacked signatures to separate signatures from the stacked signatures. After a signature separates from the stacked signatures, the servomotor slows the separator disk.
