ABSTRACT:
A cam unit (3) with cams (3a, 3b and 3c) is mounted by journals (3d) directly on plastic housing portions (1 and 2). A bracket (5) which is actuated by cam (3a) is slidably arranged on one housing portion (2) together with a back-up (26) and a clincher unit (9, 10). A slider (8) shiftably mounted on bracket (5) actuates the clincher unit (9, 10) via a cam (3c). Another cam (3b) engages a sliding block (6) which operates a stapler (15 to 17). The entire stapling device is slidable along a driven profiled shaft (4) positively coupled with cam unit (3). The cams (3a, 3b, 3c) are designed such that, in relation to the journals (3d), two diametrically opposed force-transmitting cam sections of different cams (3a and 3b and 3c, respectively) each become effective at a time. Thus, a force of action in one direction, which is caused by one cam (3b and 3c, respectively), is counteracted by a force of reaction of equal strength in the other direction, which is caused by the other cam (3a and 3b, respectively). As a result, the bearing load on the journals (3d) is kept low throughout the stapling operation.
