Abstract:
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.

Abstract:
A device for feeding sheets from a supply station aligning the sheets in an X, Y and. theta. coordinates and then gating the sheet into a work station such as the transfer station of a copier. The device includes a pair of independently servo-controlled motors disposed on opposite sides of the sheet. Each motor drives a nip roller which transports the copy sheet. Sensors are disposed to generate signals representative of sheet position in the X, Y and. theta. coordinates. A controller uses the signals to adjust the angular velocity of the motor so that the sheet is squared and is gated onto the work station. The sensors and controller are utilized to measure different parameters associated with the sheet.
