Abstract
Abstract A sheet separation device for sheet working machines, which comprises a pile table having side rails and a sheet feeder movable in the direction of height relative to the pile table. Separating elements overlap the forward edges of the uppermost sheet freely movably guided in vertical direction and laterally adjustable. A setting lever is adapted for adjustment of the separating elements and mounted swingably only about a substantially vertical axis on a complementary of the side rails. An adjustment- and securing-device is disposed likewise swingably on the side rails and operates without steps, and a guide permits movements of the separating elements in vertical direction and is disposed on the forward end of the setting lever.
