Abstract: A workpiece transfer assembly which enables a workpiece affixed to a pallet to be rotated at a work station and thereafter returned to its original position for longitudinal indexing along the transfer line. The transfer line includes a pallet locating and supporting unit which carries a first transfer bar segment. The pallet locating and supporting means includes bearing which enable the first transfer bar segment to be longitudinally indexed and rotated about its longitudinal axis. A rotary indexing assembly is provided for rotating the pallet supporting and locating device. A second transfer bar segment is carried by an intermediate transfer section. Both transfer bar segments include end features which interlockingly engage; thus, enabling the rotational and longitudinal movement to be transferred along the bar sections when they are aligned, but permitting the first transfer bar segment to be rotated out of engagement with the remaining transfer bar segments.
