Definitions

  • the device according to this invention is provided with a tube, the flat or substantially flat top end of which is equipped with a coaxial clamping element, the bottom surface of which is pressed against the top surface of the tube by means of a spring, and with a plate-shaped inserter, which is movable in such a manner that it can be brought between the tube and the clamping element.
  • Another object of the invention is to provide such a device, which, like the known device, is adapted to cut a thread and subsequently fasten one of the thread ends thus formed to the tube.
  • a cutter and a plate-shaped yarn tensioner both of which are directed towards the tube
  • the clamping element is provided with recesses, which receive the cutter and the yarn tensioner when the inserter is situated between the tube and the clamping element.
  • Such a device is specially suitable for application in spinning and twining machines equipped with an automatic dofiing apparatus, in which, after an empty tube has been placed on the spindle, the full tube which has been dotted is situated over the spinning spindle, such as for instance the combined spinning and winding machine according to Belgian patent specification 620,103. It is possible, with the aid of the device according to this invention, for the yarn in the said spinning machines to be cut between the dotted full tube and the traveller and to be fastened to the empty tube on the spindle, so that spinning can be continued immediately after dofiing.
  • FIG. 1 shows the device in the inoperative position
  • FIG. 2 shows the device during the cutting and clamping of the yarn
  • FIG. 3 shows a different embodiment of the clamping element on the top end of a tube.
  • a clamping element 1 which is made of metal or of synthetic resin and which is provided with a bore 2 having a narrowed bottom part, is centered on a tube 5, only the top end of which is shown in the drawing, by means of a pin 3, the top end of which is broadened to form a head 4. There is some clearance between the narrowest part of the bore 2 and the pin 3, so that the clamping element 1 can glide along the pine 3.
  • a screw spring 6, which is provided about the pin 3 and which is supported on the one side against the head i Patented Jan. 31, 1967 of the pin 3 and, on the other side, against the narrowed part of the bore 2, exerts a downward force on the clamping element 1, which element is hereby pressed with its bottom side on to the top side of the tube (FIG. 1).
  • the substantially cylindrical outside surface of the clamping element 1 is provided with two recesses 7 and 8, the upper and lower boundaries of which are formed by surfaces, which are perpendicular to the axis of the clamping element 1. Another recess is present in the bottom surface of the clamping element 1, in which recess there is positioned a rubber insert 9.
  • the junction between the flat bottom surface and the cylindrical outside surface of the clamping element 1 is rounded, the same as the edge of the top surface of the tube 5.
  • An inserter .10 is provided opposite each spindle on a rail, not shown in the drawing, which extends over the entire length of the spinning machine.
  • This inserter consists of a thin plate having a V-shaped incision in the side which is directed towards the spinning spindle, this incision being extended in the middle by a short slot 11 fitting about the pin 3.
  • a squarely bent plate-shaped yarn tensioner 12 and a cutter holder 13 holding a cutter 14 are fixed on the inserter 10 by means of a bolt 15.
  • a bolt 15 At the front side of the yarn tensioner 12 is an incision having the shape of a circled arch, which corresponds with the recess 7 of the clamping element 1.
  • the rail on to which the inserter 10 is fixed, can be moved horizontally in the direction of the spinning spindles.
  • the rail on to which the inserter 10 is mounted, is moved in the direction of the spinning spindles.
  • the yarn 16 is introduced into the slot 11 via the V-shaped incision of the inserter 10.
  • the inserter 10 penetrates between the top surface of the tube 5 and the clamping element 1, which causes the said element to be pressed upward along the pin 3 against the pressure of the spring 6.
  • the yarn 16 is clamped between the inserter 10 and the clamping element 1.
  • the yarn 16 is pressed into the recess 7 of the clamping element 1 by the tensioner 12 and the cutter 14 tries to push the yarn 16 into the recess 8.
  • the yarn 16 is clamped fast bet-ween the inserter 10 and the clamping element :1 on the one hand, and meets with so much resistance in the recess 7 from the tensioner 12 on the other hand, that it is cut through by the cutter 14.
  • each tube 5 is provided with a clamping element 17 made of elastic rubber, as shown in FIG. 3.
  • the clamping element 17 is fitted on the top of the tube 5 by means (B of the pin 3 and has recesses 7 and 8 to receive the tensioner 12 and the cutter 14, respectively.
  • This clamping element is operated in the same way as the one shown in FIGURES 1 and 2.
  • a device for fastening a yarn in a spinning or twining machine comprising a tube having a flat top end, a coaxial clamping element mounted on the tube end, a spring to press the bottom surface of the element against the top surface of the tube end, and a plate-shaped inserter, movable so that it can be brought between the tube end and the clamping element.
  • a device in which a cutter and a plate-shaped yarn tensioner are provided one over the other on the inserter, and the clamping element being provided with recesses, to receive the cutter and the yarn tensioner when the inserter is placed between the tube end and the clamping element.
  • a device in which a central pin is provided to fix the clamping element on to the tube end to be movable in an axial direction, and the spring around the pin forcing the element towards the top surface of the tube end.
  • a device in which at least a bottom part of the clamping element is made of elastically deformable material.
  • a device in which a side of the inserter which is directed towards the tube end is provided with a tapered incision.
  • a device in which the edge of the top surface of the tube end is rounded.
  • a device in which a side of the inserter which is directed towards the tube end is bevelled.
  • a device in which the bottom part of the clamping element at least partly consists of rubber.
  • a device in which a side of the inserter which is directed towards the tube end is rounded.
  • a device for fastening a yarn in a spinning or twining machine comprising a tube having a fiat top end, a coaxial clamping element mounted on the tube end and composed of an elastic material, a plate-shaped inserter movable so that it can be brought between the tube end and the clamping element due to the resilience of the clamping element, and means in the form of a pin passing through the clamping element and into the tube end.
