ABSTRACT:
In a machine for producing a hanging member or hanger from a wire portion, the hanging member is obtained by cutting off the wire portion from a wire unwound from a wire roll. The wire portion is inserted by feed means in the holding and deforming station of the machine, and is centered in a binding of a pack of sheets introduced into the station. Following the closing of the binding holders and movable clamping jaws, a hanging ring is bend in the wire portion by means of a movable bending tool. In the machine, the hanging member is produced fully automatically without any manual intervention and inserted in the binding of the pack of sheet, independently of the type of binding used.
