ABSTRACT:
An improved counter for documents, currency, paper money, sheets or the like achieves low weight, low power consumption, low cost and high counting accuracy by a feeding mechanism in which a first roller or set of rollers successively feeds a sheet from the bottom of a stack thereof to a second roller or set of rollers for further feeding, on a sheet-by-sheet basis, to a pair of pulling rollers which pulls each sheet at high speed and dispenses it. The first and second rollers or sets of rollers have about their respective peripheries portions having a large coefficient of friction and portions having a small coefficient of friction. Such intermittent feed rollers are synchronized to rotate with related space phases, i.e. with the low friction coefficient portion of each roller in contact with its associated sheet at the same time, thus assuring that the pulling rollers require minimal torque to pull each sheet away from the second of the intermittent rollers. Smooth, low friction flanges on each roller over an arc of length and location equivalent to said portions of small coefficient of friction on each roller assure no retention of a document, even though badly creased, after the pulling rollers take over the document.
