ABSTRACT:
A switch system for clearing spoiled items from an overlapped stream of paper products such as signatures has a three-flight conveyor belt transporting system whose middle flight may be rocked bodily so that its downstream belt support roll, functioning as a switch roll, is moved between an upper position in which it is leveled up with the next flight, and a lowered position for sending the stream, when made up of spoiled items, downwards under the next flight to a separate delivery. The side face of the upstream belt roll of this same next flight is covered by a cover for neatly separating the stream and switching it over into the downward parts under this next flight. Over the switch a backer roll is placed so as to have its weight supported on the stream of products (in turn supported by the switch roll). In this way the products are well gripped and controlled.
