ABSTRACT:
Workpieces are supported on pallets which are advanced by a continuously driven power-and-free conveyor adapted to permit each pallet to dwell in a work station when the pallet is stopped in the work station during continued driving of the conveyor. As each pallet approaches the work station, it is gradually decelerated and cushioned by a swingable stop which, after stopping the pallet, is shifted transversely to lock the pallet rigidly in an accurately fixtured position in the work station. A single pneumatically operated actuator serves to shift the stop transversely from a position in which the stop catches a pallet to a position in which the stop fixtures the pallet and then to a position in which the stop releases the pallet.
