ABSTRACT:
An apparatus forms a continuous moving stream of signatures into groups separated by gaps. The apparatus includes lugs which travel along a path having an upwardly inclined portion between belts of a conveyor. The lugs lift the signatures off the conveyor while keeping them moving at conveyor speed. Once the signatures are lifted, the lugs stop. The leading signature lifted by a lug is pinched between the lug and biasing members pressing down on the stream of signatures. A guide extends upstream from the biasing members to control stack up of the signatures behind the leading signature. When a sufficient gap has been formed, the lugs accelerate and lower the signatures back onto the conveyor.
