Abstract
The retaining device of a wire-section dispenser has a tongue-like first retaining element and a second retaining element which form boundaries for a gap. The second retaining element can be moved out of a rest position into a clamping position, which narrows the gap, and back again. When the second retaining element is located in the rest position, a stapling wire is advanced into the gap and then fixedly clamped by displacing the second retaining element into the clamping position. A cutting element, which severs the continuous stapling wire into wire sections, is synchronously moved with the second retaining element. The staple guide of a stapling head engages with its carry-along member, the wire section and moves it in the direction of rotation, overcoming the retaining force in doing so.
Claims13
An apparatus for wire-stapling of multiple-sheet printed products comprising:
- a movable stapling head including a carry-along member;
- a wire-section dispenser mounted adjacent to said movable stapling head, said wire-section dispenser including a wire guide for guiding a length of stapling wire that is adapted to be advanced in a stepwise manner along its longitudinal direction,
- a cutting element located downstream of said wire guide, in the advancement direction of said stapling wire, said cutting element functioning to sever individual wire section from the advancing stapling wire,
- a retaining device including retaining elements that define a gap for receiving said severed wire sections, said retaining elements being mounted on said wire-section dispenser such that they can move relative to one another from a rest position to a clamping position and back again, such that when said retaining elements are in said clamping position said gap has been narrowed,
- said retaining device being arranged with respect to said wire guide such that the stapling wire moves with its leading end first, between the retaining elements which are in said rest position, and the retaining elements are then moved into the clamping position, before the cutting operation is performed;
- said wire sections adapted to lie freely within said gap with a region outside the gap and to be carried along by said carry-along member of said stapling head, said stapling head is adapted to move past said retaining device in a direction that extends transverse with respect to the position of said wire section in the gap, such that action is performed on said free region of said wire section and said wire section is moved out of said gap which is open downstream in the movement direction.
