Abstract

An apparatus for transferring a relatively flat object from a first station to a second station includes a support for the object at the first station, a substantially closed housing, and a piston disposed therein for sliding movement from a normal position to an activated position. An actuator extends through the housing and is integrally formed with the piston for sliding movement thereby. Compressed air is selectively directed into the housing for movement of the piston to the activated position, whereby the actuator strikes a blow edgewise of the object for propelling it toward the second station along a predetermined path. A pair of fingers disposed at the second station define therebetween a portion of the path along which an incoming object enters the second station. Each finger includes a path wall having an end surface extending generally inwardly from the finger for blocking the object path for halting object movement. A spring pawl extending partially into the path from each finger prevents rebounding of the object from the end surfaces.
