ABSTRACT:
In a device for isolating and feeding the lowest sheet (1) in each case from a stack (2), with pushing-out elements (9) which grip the rear edge (3a,3b) of the sheet (1) and transport it through, under a front-edge stop (5), into a pair of drawing-off rollers (6), can be moved forwards and backwards, are mounted on a cross-member (7) and have faces (9a), which are optionally front-mounted, for supporting the rear region of the stack (2) and also have bearing elements (11, 12) supporting the stack (2), and lateral abutment strips (13), the front edge (4) of the said stack being constant with respect to the sheet length (H), provision is made, in order to achieve high isolating outputs and faultless feeding of the sheets (1) with a device of simple design, for the cross-member (7) which receives the pushing-out elements (9) to be guided so as to be capable of travel in a linear guide (14), and for there to be directly associated with the said cross-member (7), for the driving movement of the latter, a linear motor (15) whose path of travel (A) comprises both the isolating stroke (B) and also an adjusting path (C) which is intended for setting the sheet length (H).
