Method and apparatus for replacing incomplete printed products in the production of newspapers, magazines and similar products

摘要

A method and apparatus for assembling printed products. The method and apparatus involve the selective delivery of the printed products to receiving devices situated in succession along a production line formed by a plurality of controlled sheet feeder stations. Printed products are selectively supplied to a receiving device at a discharge end of the production line, and transferred to a helical circulation track guiding a plurality of further receiving devices driven in synchronism with the production line through a feed path disposed between the discharge end of the production line and the circulation track. Any incomplete printed products are removed from the printed products, and replaced with replacement complete printed products by delivery of the replacement complete printed products to respective receiving devices of the circulation track corresponding to removed incomplete printed products at a feed point in the circulation track through the feed path. The feed path is thus adapted to transfer both originally complete printed products and replacement complete printed products to the circulation track.
