Abstract
1,254,854. Separating sheets. RICOH K.K. 16 Dec., 1968 [26 Dec., 1967], No. 59620/68. Heading B8R. [Also in Division B6] The separation of sheets from a stack 5 by rollers 2 mounted on a shaft 4, Fig. 2, is aided by various means which retain the lower sheets of the stack while only the top sheet is fed. The sheets may be provided with small diameter holes 6, the edges of the holes (Fig. 3, not shown) in adjacent sheets interengaging to prevent movement in the plane of the sheets; the holes may not be completely circular and may be in the form of arcuate cuts (Figs. 4 and 5, not shown); the edges of the sheets may be abraded, or may be provided with adhesive (Fig. 6, not shown). The treatment of the sheets is generally operative on the leading edges relative to the feed direction.
