摘要

A signature aligning and trimming apparatus wherein a stream of overlapping signatures are conveyed past first and second alignment stations on a lower conveyor belt system. Immediately after the second alignment, and while the signatures are still carried by the lower conveyor belt system, the signatures are engaged by an upper conveyor belt system and are pressed firmly against the lower belts as they are moved over large diameter rollers. The edges of the signatures are trimmed by single cutting wheels positioned to engage the edges of the signatures as they move over the top of the large diameter rollers. A pair of anvil plates, which are positioned beneath the cutting wheels and are rotatable with the large diameter rollers, provide a supporting surface for the signature edges against which the cutting wheels act in trimming the signature edges.
