In order to allow the use of a crank knife (3) for cutting-off individual pieces (B) from a strand of material (M) before they are pushed into the jaws (6) of a gripping wheel, the direction of feed of the strand of material is disposed obliquely to the axis (A) of the gripper wheel (7), the pusher-in (8) is attached to a pushing-in rocker (9) which is connected via a pull rod (10) with a crank (11), the pivot point (13) of the pushing-in rocker (9) is situated substantially at the point of intersection of the centre lines of the material strand (M) and of the pushed-in sweet (B), and an actuating lever (14), pivotally journalled on an axis (15), is disposed at the pivot point (13), with which (actuating lever) a connecting member (16) and a pivoting lever (19) having a common pivot bearing (17) are associated, the pivoting lever (19) being journalled on an axis (18) and the pivot bearing (17) being connected via a link (20) with a crank (21). <IMAGE>
