Definitions

  • the present invention relates to a stapler according to the preamble of claim 1.
  • a stapler of this type is known for example from GB-PS 640,073.
  • This has a cube-shaped die, the front of which is chamfered.
  • a slot running approximately in the horizontal direction is machined into the die from the front, into which a section of a wire drawn off from a roll can be inserted from the side.
  • a stamp interacting with the die is pivotally mounted on a lever on a horizontally extending shaft and has two lateral bending flanks which, when the punch is pivoted from an upper rest position into a lower clamp setting position, the two arms projecting laterally beyond the die by means of a on the punch bend the attached knife from the wire cut wire section towards the bottom.
  • Another stapler is known from CH-PS 549 443.
  • a stamp and a plunger are slidably guided.
  • the stapling head with the printed products to be stapled and placed on a collection chain is moved along and then returned to the original position against the direction of conveyance of the collection chain.
  • the stitching head runs along a resting rest plate with two control cams.
  • One control cam moves the stamp from a rest position spaced apart from the collecting chain to the clamp setting position and back again, and the other actuates the plunger to eject the clamp from the stamp when it is in the clamp setting position and to simultaneously set the clamp into the printed products.
  • a die On the support part is further a die is pivotally mounted in such a way that when the plunger is lowered it is pivoted out of the region of a recess in the punch and the region of the plunger.
  • a lever pretensioned against the die is pivotably mounted on the die.
  • the leading section of a wire is inserted between the die and the lever in a direction perpendicular to the sliding direction of the stamp and the plunger by means of a wire conveyor device which is also mounted on the support part and is actuated by the plunger.
  • a cutting arrangement is first actuated by the latter, which separates the wire section held by the lever and the die from the rest of the wire, and then the wire section is bent around the die to form a clip.
  • the plunger is then lowered, an eyelet is first bent on the clamp and when the plunger is lowered further, while simultaneously swiveling the die out of the region of the stamp and releasing the lever from the wire section, the clamp is ejected from the stamp and pressed through the printed products. Benders are provided on the collecting chain, which bend the ends of the clamp that have been pushed through the printed products.
  • this known stapler the wire is cut to length, the clip is formed from the cut wire section and the clip is set in a very small space. This leads to a very compact but also very complex construction of the stitching head.
  • rotary staplers are known from US Pat. No. 2,717,383 or the corresponding DE-AS 1 055 499 and US Pat. No. 3,762,622, in which the stitching head is in each case arranged eccentrically on a rotating support disk.

  • the clamp is pressed out of the stamp and through the printed products by means of a plunger.
  • the free ends of the clamp are bent by means of a bending head that also runs all the way round. While the staple is being set, the stitching head undergoes small corrective swiveling movements in order to adapt the stamp to the speed and direction of movement of the printed products.
