Abstract

Apparatus and process for collating folded signatures which are removed from a stack of signatures and placed in parallel side-by-side relationship on saddle members. The saddle members move in a direction transverse to the folds in the signature, and thus spacing of the saddle members is close together and the entire apparatus and process can be performed at a high speed, in that arrangement. A signature pickup device is employed for removing the signatures from the stack in a stream relationship and delivering them directly to a collector where a flap opener can be employed for positioning the signature flaps on opposite sides of the collector saddle members.
