Abstract
A flexible sheet handling apparatus having particular application to the handling of documents in a copy machine is disclosed. The sheet handling apparatus includes a curved drive surface, a drive for driving the surface, and a curved reaction surface which defines a curved sheet path extending along the drive surface, the reaction surface being out of contact with the drive surface.
Claims2
Sheet handling apparatus comprising a drive roller, means for rotating the roller, a pair of stationary curved guide surfaces for urging a sheet in a curved path against the periphery of the roller, the guide surfaces include straight lead in portions generally tangent to curved portions thereof while being spaced from the roller at opposite sides respectively thereof and arranged radially inwardly of the roller periphery such that the sheet is corrugated in the lateral direction in order to increase the beam strength of the sheet and thereby improve the coupling force between the sheet and the roller.
