A compact single bin finisher adaptable to form collated sets of copy sheets outputted from a copier/duplicator. The finisher includes an output tray adapted to support the collated sets and to support copy sheets during accumulation of a set. A set accumulation module having an accumulation platform is disposed in a plane which is displaced both horizontally and vertically from the output tray. A transport device carries sheets into the accumulation module. A predetermined number of sheets form a set which may be stapled and is ejected onto the output tray.

Finisher--exit pocket module for copier

Device for separating and feeding sheets in seriatim from a stack to a processing station. The device includes a pin which periodically contacts and forms a pivot point on the stack. A rotary wave generator is disposed to rotate about the pivot point. The rotary wave generator periodically contacts a topmost sheet in the stack and shingles (that is separates) the sheet from the stack. The shingled sheet is fed into a paper sheet aligner and into the processing station.

Wave generation amplification apparatus for cut sheet paper feeding

Device for separating and feeding sheets in seriatim from a stack to a processing station. The device includes a pin which periodically contacts and forms a pivot point on the stack. A rotary wave generator is disposed to rotate about the pivot point. The rotary wave generator periodically contacts a topmost sheet in the stack and shingles (that is separates) the sheet from the stack. The shingled sheet is fed into a paper sheet aligner and into the processing station. A variable or ramped force and/or a variable velocity is applied to the shingler. The force and/or velocity begins at a relatively low value and increases until a sheet is sensed downstream from the stack. This enables the feeding of a wide range of paper types and weights.

Shingling with controlled force and/or velocity

Sheet-like articles, such as paper, entering one or more support trays are aligned in one or more vertical stacks by a pair of rotating drive devices positioned vertically and adjacent to opposite sides of the support trays. The rotating drive devices include a plurality of resilient flaps mounted to a support member. The flaps are configured to reach over a stack of sheets thereby contacting a sheet on its top surface as well as on its edge.
