Abstract
A stapling apparatus (1) has a stationary stapling head (9) and a counterbearing(13), fastened to a slider(4) and equipped with a clinching apparatus (14), that is fastened to slider (4). The slider (4) has parallel clamping surfaces (4d, 4e), associated with which are a clamping element (19), mounted in stationary pivotable fashion and having clamping jaws (19c, 19d) and edges (19e, 19f), that can be positioned by a torsion spring (21), pivotably about a bearing (19a), against the clamping surfaces (4d, 4e) of the slider (4). The clamping element (19) is spring-loaded opposite to a movement direction 'B' of the slider (4). The pivot bearing (19a) of the clamping element (19) is arranged at a distance (r) from the slider (4) that is related by a ratio l/r<2 .mu., which effects self-locking, to the length (l) of the clamping jaws (19c, 19d). When a force which attempts to move the slider (4) opposite to the direction of arrow 'B' acts, as a result of the stapling operation, on the counterbearing (13), jamming of the clamping element (19) occurs by self-locking, thus causing immediate blocking of the slider (4). After completion of the stapling operation, an actuator (5) of the clinching apparatus (14) releases the blocling of the slider (4) by positive pivoting of the clamping element (19).
