Abstract:
A delivery apparatus for sorting a single stream of signatures into two or more streams, the apparatus includes two counter-rotating bucket assemblies. Each bucket assembly includes a plurality of buckets spaced from one another along a common axis. The respective common axis of each bucket assembly is disposed parallel to the common axis of the other. Each of the buckets of one of the bucket assemblies is disposed adjacent to and in a respective common plane with a respective one of the buckets of the other of the bucket assemblies. Further, each of the buckets includes a plurality of blades, the tips of the blades of each bucket defining a circumference. A respective circumference of one bucket overlaps the circumference of the other bucket disposed in the common plane. Two neighboring blades have respective surfaces defining a slot therebetween. Each slot includes a first generally wedge-shaped portion defined by a first planar surface and a second planar surface disposed at a first angle from the first planar surface, and a second generally wedge-shaped portion defined by a third planar surface and a fourth planar surface disposed at a second angle from the third planar surface. The second angle is smaller than the first angle.
Abstract:
Provided is a sheet diverter for directing signatures moving in serial fashion along a diverter path to one of a plurality of collation paths. The sheet diverter includes a pair of diverter rolls for directing a signature to one of the plurality of collation paths and a diverter wedge for deflecting the signature to a selected one thereof. The diverter wedge is positioned between the diverter rolls so as to reach high into the diverter path thereby providing increased support to the signature as it travels from between the diverter rolls to the diverter wedge. The diverter rolls are permitted to intermesh with the diverter wedge so as to allow the diverter wedge to be so positioned.
Abstract:
An apparatus for decelerating signatures moving in tandem fashion through sheet processing equipment is provided. A pair of counter-rotating cams lying in general face-to-face relation along a travel path of the signatures reach into the travel path of the signatures to effectively grab the trailing end of each signature so as to decrease the speed of each signature as the signature continues or to further processing equipment in the sheet handling system. Also provided is a guide assembly which increases control over the signatures during the decelerating process and during transport of the signatures to further downstream processing equipment.
