An improved deleaver for separating the plies of multiple-ply, continuous business forms stationery assemblies with or without interleaved carbon plies. The deleaver includes an input end and an output end having a plurality of ply-receiving pockets. Intermediate the output end and the input end is a first driving device for engaging the continuous business forms assembly along a path of stationery travel to drive the same from the input end to the output end. Located forwardly of the drive means is a pinfeed device for engaging the assembly and forwardly of the pinfeed assembly is an adjustable drag device. The pinfeed device includes a non-positive drive that tends to drive the stationery along the path faster than the rate at which the stationery is driven by the drive means and, due to the effect of the drag device, operates in bucking relation therewith to produce smooth deleaving at all points in a deleaving run. Also disclosed is a deleaver having a positive drive for stationery driving components including timing belts and a unique hold-down roller assembly for cooperating with driving rollers forwardly of each of the pockets in the output end.
