ABSTRACT:
A paper anti-skew device for maintaining alignment and preventing skewing of sheets fed from a stack into a copy sheet mass in an electrostatic copying machine for producing copies of documents. Sheets are fed from lead edge by a top feeding pneumatic device in seriatim. The anti-skew device rests on top of the stack of sheets along the trailing edge of the stack and is longitudinally coextensive with the trailing edge thereof. Corner portions extend from the longitudinal portion of the member at an angle of 90.degree. for a predetermined distance to maintain alignment of the trailing corners of the topmost sheets as they are fed and which may stick and skew relative to the direction of the copy sheet path in the absence of the anti-skew device.
