ABSTRACT:
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.
