Definitions

  • US Patent 3,169,559 describes a ligature pliers using staples to perform simple ligatures of cross irons.
  • This device includes a carriage to push the staple and an opposite tweezer to make a journal.
  • this device does not make it possible to make dead turns around the irons, or to cut the excess of wire after tying.
  • the transverse grooves 26 and 27 of the shoes have annular grooves 38 and 39 respectively arranged in the extension of the side walls 17 and 18 of the slide 15.
  • the groove 39 has a width substantially equal to twice the diameter of a clip 1, and is arranged in a slightly oblique plane relative to the direction of the transverse grooves 26 and 27.
  • the annular groove 38 has a width substantially equal to the diameter of the wire forming the clip 1, and is arranged in a plane substantially perpendicular to the direction of the transverse grooves.
  • the knives 60 and 61 are arranged between the support 48 and the shoes 24 and 25, the cutting part of the knife 61 being slightly in front of the lower opening 55, and the knife 60 being arranged so that, in the position of extreme advance of the guide 41, the cutting part of this knife 60 is slightly set back from the front plane face 29 of the transverse grooves 26 and 27.
  • the recoil movement of the support 48, under the action of jack 49, as shown in FIG. 13, causes the clip 1 to be pinched between the knives 60 and 61, and to cut it off.
  • the turret 47 is then caused to rotate to allow the ejection of the drop of wire 62 by the evacuation tunnel 57.
  • the elements are then brought back into the retracted position to release the transverse grooves 26 and 27 from the shoes and allow the removal of the clamp.
