ABSTRACT:
A sheet-reversing device suitable for use in copying machines and other sheet-handling machines has a main roller and a feed-in and a feed-out roller which are frictionally driven by the main roller. The axes of those rollers remain fixed with respect to each other. When a sheet is fed to the nip between the main roller and the feed-out roller, it is transported without reversing, but when fed up to the nip between the main roller and the feed-in roller, it enters into a switchback path and the formerly trailing edge of the sheet is fed to the nip between the main roller and the feed-out roller and then is reversely transported (trailing edge first). By selecting the appropriate inlet path, the sheet is selectively reversed.
