Abstract (en)

A stapling machine incorporates a spring to apply force to a staple pusher (20,47), which pushes staples in a staple magazine (44) towards a staple ejection slot (5,46). The spring comprises a spring strip (21,49) having one end thereof wound into a spiral coil (22,50), the spiral coil (22,50) being received within a cavity (3,52) which retains the coil (22,50) in a predetermined position, a portion of the spring extending from the spiral coil (22,50) to the staple pusher (20,47). The spring (21,49) applies a constant force to the staple pusher (20,47), facilitating ejection of the last few staples. The design facilitates easy assembly of the stapling machine. <IMAGE>
