ABSTRACT:
Printing works products, book blocks having a spine for example, are transferred from a feed conveyor to a receiver with selected products being rotated through an angle of 180.degree. during the transfer. The products to be rotated are frictionally engaged, slowed to a standstill during a first phase of rotation and thereafter accelerated and discharged when rotation is completed. The synchronized first phase of rotation and arresting of product motion is controlled such that the center of gravity of the product will be located approximately in alignment with the axis of rotation when rotation through an angle of approximately 90.degree. is completed.
