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.

Conveying apparatus with product reorientation capability

A transfer device for books, inner books, newspapers, stacks or papers or similar products that are fed to a distribution point in a product stream on a high speed conveyor which includes a rotationally driven accelerator/decelerator. The speed of the accelerator/decelerator is controlled in such a manner that the product to be distributed is first accelerated to separate it from the next succeeding product in the product stream and the product is then controllably slowed so that it may be stopped at the distribution point without damage.
