ABSTRACT:
An alignment and centering device is associated with a carrier having two fork arms and a transverse base to which the rearward ends of the fork arms are attached and which is connected with a conveyor mechanism in a framework with a plate-loading station, and a plate-feeding device therein for advancing plates toward the free fork ends of the fork-shaped carrier in a plate-advancement plane. The alignment and centering device comprises rearward and forward engaging members on an outer wall of each fork arm, facing away from the other fork arm; aligning devices for engaging the rearward engaging members; and forward, centering aligning devices for engaging the forward engaging members on the fork arm after the rearward engaging members have been engaged by the first aligning devices. The alignment and centering device is stationary on the framework and the first and second aligning devices are displaceable therein parallel with the plate-advancement plane.
