Abstract
A machine for arranging signatures in bundles includes a receiving conveyor onto which signatures are placed. The receiving conveyor moves the signatures in a shingled condition between deflecting surfaces to cause the signatures to assume an edge-standing condition. The edge-standing signatures move onto a consolidating conveyor so they move closer together. The signatures pass from the discharge end of the consildating conveyor onto an accumulating conveyor, which normally advances the signatures at a slightly slower speed than the consolidating conveyor. When enough signatures to make a bundle have passed onto the accumulating conveyor, the velocity along that conveyor is increasd substantially, and the consolidating conveyor is stopped to produce an isolated group of edge-standing signatues on the accumulating conveyor. A sword is extended into the signatures at the juncture of the consolidating and accumulating conveyors and pushes the signatures on the accumulating conveyor forward to form a distinct gap in the signatures to the rear of the sword. Compression fingers extend into the path behind the isolated signatures on the accumulating conveyor and push them forward. The sw…
