Abstract
Staple forming arrangement () forming part of a stapler () in which a workpiece (), primarily a sheaf of papers, is stapled together. The arrangement includes a bending punch (), which is driven by a drive mechanism () and which bends elongated staple blanks () over a bending cushion (). The staple blanks, which are stored in a magazine () in the stapler and are fed to the bending cushion by an integral feeding device (), are bent essentially into a U-shape having a crown () and a first leg () and a second leg (), respectively and whereupon the bending punch is withdrawn from the bent staple by the drive mechanism. After the withdrawal of the bending punch from the bent staple, the bent staple is fed by the feeding device to a staple guide channel () in which the staple is driven by a drive blade () incorporated in the stapler into the multi-piece workpiece in order to staple the pieces together. The arrangement () is provided with a first and second leg catcher deviceand, respectively which catch and block the respective staple legs (and), preventing them from springing back after bending until the staple has been fed into the staple guide channel.
