Definitions

  • Devices are already known for cutting a textile thread and retaining at least one of its strands by pinching between two parts urged against each other by a spring, one of these parts being constituted by a head of a rod , the other part surrounding this rod, a space being formed between this other part and the head of the rod, a cutting member being housed in said space.
  • a device of this kind is described for example in Swiss patent N ° 635,380.
  • the invention aims to reduce the manufacturing cost of such a wire cutter device, while making its use easier.
  • the thread-cutting device of the aforementioned type is characterized in that the cutting member is constituted by a part mounted on the part of the rod which passes through said space, this part having at least one branch extending radially in said space, this branch having a slot extending to its end, the two parts of the branch located on each side of the slot being oriented so as to move away from either side of a perpendicular radial plane to the axis thereof, in order to provide a V-shaped groove therebetween.
  • the device for cutting a textile thread and retaining at least one of its strands by pinching between two parts comprises a rod 1, having a head 2 and a threaded portion 3.
  • Another part 4 in general form sleeve can slide on the rod 1 and is subjected to the action of a spring 5 bearing against a stop ring 6 to push this part 4 until it comes to abut against the head 2 of the rod 1.
  • Part 4 has a circular recess 7 facing a circular recess 8 of the head 2, these two recesses facing each other to form a space in which is housed a cutting member 9, mounted on the part of the rod 1 which crosses this space.
  • the cutting member 9 is constituted by a stamped steel plate to present three branches 10 and a central hole 13 whose section is non-circular, thanks to a flat 14.
  • Each of the branches of the cutting member 9 has a slot 15 so as to divide the branch into two parts 11 and 12 which are oriented so as to move away from either side of a radial plane perpendicular to the axis 1, moving away from the axis of this rod.
  • the parts 11 and 12 form between them a V-shaped groove 16, these grooves constituting the cutting parts of the member 9.
  • the head 2 and the sleeve 4 have conical portions 17 and 18 respectively which face each other to form a groove for guiding the textile thread to be cut.
  • the rod 1 has a flat 19 intended to cooperate with the flat 14 of the cutting member 9 so as to prevent the rotation of this member 9 on the rod 1.
  • the user presses this thread into the groove formed by the conical portions 17 and 18, which slightly separates the sleeve 4 from the head 2 by a slight movement against the action of the spring 5.
  • the thread is housed in the space 7, 8 and engages in at least one V of the cutting member 9.
  • the V-shaped grooves 16 of the member 9 are located substantially in the contact plane of the head 2 with the sleeve 4.
  • the wire being clamped between the sleeve 4 and the head 2, it suffices to exert a pull on a strand of the wire to force it towards the bottom of the groove 16 and easily obtain his cut. After this operation, the other strand of the wire remains pinched between the head 2 and the sleeve 4 and, if necessary, can be released easily by a slight pull.
  • the device described can be fixed by screwing, or in any other way, on any textile machine where one needs to be able to easily cut a thread.
  • This device can advantageously be combined with the screw fixing the presser foot on a sewing machine.
  • the cutting organ could have only one or two V-shaped branches, but tests have shown that a three-branched organ gave better results.
  • the sleeve-shaped part 4 could be fixed to the frame of a machine, the rod 1 then being devoid of the threaded portion 3 and being able to move against the action of the spring 5.
  • the head 2 of the rod 1 could be made integral with the latter by any known means, instead of having come in one piece with this rod.
