摘要： A stapling device (1) comprises a clincher unit (3) with bending elements (30 and 31) by which the ends of a staple (34) driven through a sheet stack (35) are folded and bent onto the sheet stack (35). The bending elements (30, 31) are actuated by a pushrod (26, 27) whose end side facing the bending elements (30, 31) is provided with rotary rollers (28, 29) which roll on the bending elements (30, 31) during each working stroke in order to clinch the ends of the staples. During the return stroke of pushrod (26, 27) the reduced frictional load causes slippage to occur between the rollers (28, 29) and the bending elements (30, 31) so that continuously alternating contact points are brought into engagement. This results in a uniformly distributed, and consequently reduced, load on the rollers (28, 29) by which the service life of the clincher unit (3) is prolonged.
