Definitions

  • the invention relates to a method of tacking tough material especially for closing sample bags by means of a plier-like stapling device carrying an anvil on one plier arm and a staple supplying channel with means of a plier-like stapling device carrying an anvil on one plier arm and a staple supplying channel with staple driver on the other plier arm which is movable toward the anvil.
  • Sample bags are, as a rule, provided at the fill-in margin with pre-punched holes for receiving the closing clamps, clips or staples.
  • the invention is also directed to a staple tacking device for carrying out the new method.
  • the invention starts out from a staple tacking device in form of a plier, which has an anvil on one of its arms and on the other arm, which is movable toward the anvil, a staple supplying channel with a staple driver.
  • An important feature of the invention resides in the provision of the movable arm on both front sides of the staple exit opening with one pre-punching nose or projection each and in the provision on the other plier arm on both sides of the anvil with one guide each for a turn-over anvil.
  • the pre-punch noses provide the essential advantage that even for tacking tough material to be tacked, tacking staples can be used which correspond in regard to their material as well as in regard to the shape of their points to the rules and regulations of postal authorities, particularly those of the Federal Republic of Germany, which require for sample bags, that:
  • the staple has no points which could cause injuries to a hand or to other postal goods
  • a swing arm may be added to the movable plier arm, the free end of which grips the staple driver and which is connected with an operating lever, the shorter arm of the latter gripping under a knob or the like of a turn-over anvil provided on the swing arm. In this manner the tacking procedure, which takes place in several stages, is achieved by swinging one single operating lever.
  • an unobjectionable turning-over of the legs of the staple is achieved thereby that the pre-punching noses are longer than or at least as long as the thickness of the material to be tacked and that they form turn-over edges for the legs of the staples during the turning over.
  • the anvil may be provided with wedge-shaped front surfaces which widen or spread the staple during the penetration of the material to be tacked so as to bring the points or tips of the widened staple into the operating reach of the turn-over anvil.
  • FIG. 1 is side elevation of a staple tacking device in the position of rest
  • FIG. 2 is a side elevation of the device according to FIG. 1 in the position at the end of a stapling operation
  • FIG. 3 is a horizontal section along line IIIIII of FIG. 1 on a larger scale
  • the staple tacking device is attached to a supporting structure consisting of a standard 1 and a two-plate cantilever 2 clampable to the standard at a desired height.
  • a hollow rod 3, constituting the movable plier arm of the device, is mounted swingably about a bolt 4 between the two plates of cantilever 2.
  • Hollow rod 3 is formed, in a manner known per se, as staple supply channel.
  • a staple drive-out plate or blade 5 is slideably mounted transversely to rod 3 on the lower end of rod 3, as likewise known per se.
  • a rod 6, forming the other plier arm, is rigidly secured between the two plates of cantilever 2 and has its lower end angled-off to constitute the anvil 7, which is customary for this type of tacking devices.
  • the anvil lies at an appropriate height relative to the drive-out blade 5.
  • a bifurcated swing arm 8 is also mounted in cantilever 2 on a bolt 4, the prongs of this arm extending on both sides of cantilever 2 and rod 6.
  • the end of swing arm 8 is formed as turn-over anvil 9, the anvil surfaces of which being arranged on both sides of anvil 7.
  • An operating lever 15 is journal by bolt 14 to swing arm 10, the longer arm 16 of this lever being provided with a handle and its shorter arm with a notch.
  • the bifurcated front end of lever arm 17 grips under one each of two outwardly projecting knobs 19 on swing arm 8.
  • Swing arm 10 is connected with cantilever 2 by means of a spring 20.
  • the action of spring 20 is weaker than that of spring 13. Under the influence of spring 20, swing arm abuts stop 21 of cantilever 2.
  • Hollow rod 3 is on both front sides of the exit opening for the tacking staples provided with a pre-punching nose 22, the length of which is slightly larger than the thickness of the sample bag customarily to be closed.
  • the shape of the pre-punching nose is visible particularly from FIG. 3.
  • the inside margins 23 of the pre-punching noses 22 extend parallel to one another, whereas the outer margins 24 extend at acute angles to the inner margins.
  • FIG. 3 also reveals that anvil 7 is provided with wedge-shaped front surfaces 25 for widening out the staple upon the latter being punched through the material to be tacked, the shank of anvil 7 having a width 26 which is smaller than the distance between the points or tips of the widened-out staple, as visible from FIG. 4.
  • Swing arm 8 is returned by a leaf spring 29, attached to cantilever 2, to the position shown in FIG. 1.
  • a stapling device for tacking together several layers of a multi-layer article: staple delivery means; an anvil; means adapted to move said delivery means and said anvil toward and away from each other; said staple delivery means comprising means for guiding a staple and being open toward said anvil so as to permit a staple to leave said guiding means in the direction toward said anvil; a driver supported by said delivery means for back and forth movement; punching means at both sides of and at the same level with said guide means; said punching means being adapted to pre-perforate an article to be tacked while being held between said anvil and said delivery means; said anvil being adapted to permit said punching means to penetrate through and beyond said article while the latter is being held between the anvil and said delivery means; means for sequentially moving said anvil and delivery means toward each other in perforating an article held between them by said punching means and then pushing a staple by said driver through the perforations of the article; and means adapted to turn the legs of a staple having been pushed through the article at the
  • a staple tacking device a supporting structure; a first main arm rigidly secured to said supporting structure and having a free end carrying a main anvil; a second main arm pivoted to said supporting structure, constituting staple supply means and having a free end provided with a staple outlet opposite said main anvil and with a reciprocably guided driver for a staple; punching means on said second main arm on both sides of said outlet and said main anvil; a first swing arm pivoted to said supporting structure and carrying a turn-over anvil embracing said main anvil on both sides theerof; a second swing arm pivoted to said supporting structure having a free end engaging said driver; and means for sequentially moving said second main arm toward said first main arm, then moving said second swing arm toward said first main arm, and finally moving said first swing arm relative to said first main arm toward said second main arm.
  • said supporting structure comprises a standard and a cantilever rigidly secured to said standard, in which said cantilever has two plates leaving a space between them, in which said plier arms and said second swing arm are mounted between said plates, and in which said first swing arm is bifurcated and. has the two prongs of the bifurcation mounted on the outside of said plates.
  • Staple tacking device in which said anvil has a wedge-shaped front face adapted to widen a staple upon the latter having been pushed through the perforations of an article to be tacked.
