Abstract
Method and apparatus of handling signatures which are first presented to a rotating type of trimmer and are then collected in a compensated stack where the folds of the signature are positioned on opposite sides for levelling the stack. The trimmer includes a clamp which secures the signature while it is being trimmed on its three open edges, and the clamp can then be actuated to move the signature to a collection location where the compensated stack of signatures is formed.
