Sheet reversing in copying machine and other sheet-handling machines

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