Abstract

A staple wire cutting element (4) is mounted displaceably on a stapling device (1) in which staple wire segments are shaped into a staple and driven into a sheet stack. A control lever (8) that is in engagement with a radial cam unit (6) engages the cutting element (4). The radial cam unit (6) is driven via an overrunning clutch (10), one end of which has a gear (11) which is fixed to the radial cam unit (6) and engages into a gear (5b) of a stepping motor (5). The other end of the overrunning clutch (10) has a gear (12) which is fixed to a transport wheel (13) for staple wire transport. A gear (27), which is mounted displaceably along its rotation axis and is mounted rotatably about the same rotation axis as the gear (5a), engages into the gear (12). The gears (5b, 27) are equipped at their sides facing one another with tooth sets (28). For backward transport of the wire segment which is ready for staple shaping, the displaceable gear (27) is brought into engagement with the gear (5b), thus allowing the wire to be transported backward, bypassing the overrunning clutch (10).
