Kopiermaschine mit einer Vorrichtung zum variablen Einschneiden der Papierränder.

摘要

In a copier, automatically providing tabbed sheets in the output of the copy sheets (26) of the copier, with an integral, on-line, copy sheet tab cutting system (30). Selectably varying the tab cutting position and cut tab size provides sequentially varied tabs (28). A selected tab may be cut on any selected sheet being fed through the regular copy sheet (paper) path of a xerographic or other copier or printer. This may be done by temporarily stopping and registering (32, 34) the leading edge of the selected sheet, and then shear cutting off the untabbed areas of the trailing edge of the sheet by moving (47, 44) a shear cutting assembly (38, 39) transversely across the direction of movement of the copy sheet path of the copier upstream of the lead edge registration position at slightly less than the sheet width distance, and providing irregular width cutting of the sheet (non-cutting of the tab area). The latter may be provided by a tab interruption (38b) or offset of mating tab cutting shear wheels on the shear cutting assembly, and this may be variably repositioned (54, 50) by indexed rotation of the shear wheels to change the tab cutting position.
