Sheet material collating system

摘要

A sheet material collating system includes a pair of tubular metal guide rails. A plurality of plastic carriers are supported by guide rollers on the guide rails. A plurality of plastic pockets for receiving signatures are supported on the carriers in a position cantilevered out from the guide rails. Each carrier has a set of drive teeth. Drive element located along the guide rails includes an externally toothed drive belt which is engageable with the drive teeth on the carriers, as the carriers move past the drive element, to drive the carriers and thereby the pockets along the guide rails.
