ABSTRACT:
A corner buckle feeder has a singulation roller and feed roller for initially separating and feeding glossy paper. The front corners of a sheet stack are unsupported in order to minimize the intersheet frictional forces that are influenced by temperature and humidity. The axis of the singulation roller is disposed at an angle with respect to an edge adjacent to the lead edge of the top sheet. The singulation roller drives the adjacent edge inward and the top sheet deforms along the leading edge to form a buckle.
