  • FIG.1
  • JNVENTORJ G C. van aZew Berg United States Patent TUBE FOR RING SPINNING FRAME AND APPA- RATUS FDR CONNECTING A YARN END T0 SAID TUBE Giisbertus C. van den Berg, Groenlo, and Hendrik Glastra, Enschede, Netherlands; said van den Berg assignor to said Glastra Filed June 27, 1962, Ser. No. 205,635 Claims priority, application Netherlands July 13, 1961 3 Claims. ((11. 57106)
  • the invention relates to tubes for ring spinning frames, the term spinning frame being meant also to comprise other frames for the production of yarn, such as doubling and twining frames, which comprise a rotating spindle onto which yarn is wound while being twisted.
  • a known problem connected with ring spinning frames is that of restarting the spinning process after dofling, that is to say after a full tube on a spindle has been replaced by an empty one, for the yarn end coming from the drawing rollers must be connected to the tube on the spindle in such a way that it does not get loose again when the spindle starts rotating.
  • a tube according to the invention is provided with a brush-like top end, consisting of a number of thin, flexible pins which are axially directed and placed closely together, so that a thread or yarn, laid on them and pushed or pulled between them, will be held sufiiciently fast for starting the spinning process.
  • the yarn end will easily come loose when the yarn on the tube is wound off by a winding machine.
  • the invention further relates to a device for connecting a yarn end to the above-described tube on a ring spinning frame equipped with an automatic or semi-automatic doiiing apparatus, for instance the combined spinning and winding machine described in our co-pending application, Serial No. 205,636, filed June 27, 1962.
  • This device comprises a thread cutter of the type that can cut the yarn between the traveler and the doffed tube and can hold one yarn end, a hingingly mounted arm bent in a V, means for operating said cutter and means for moving said arm downwards when the device is moved towards the spinning spindle.
  • FIG. 1 shows a tube according to the invention
  • FIG. 2 shows a perspective view of a device for conmeeting a yarn end to the tube of FIG. 1;
  • FIG. 3 shows a detail of the device of FIG. 2.
  • the tube 2 which is placed on a partly shown spindle 1, is provided at its top end with a metal reinforcement 3, on which a plate-shaped element is fixed by means of a cylindrical connecting piece 4 having a smaller diameter.
  • the recess thus formed between the reinforcement 3 and the element 5 can co-operate with a forked gripper of a dotting apparatus not shown and not forming part of the invention.
  • the element 5 is provided with a number of pins 6 which are preferably made of elastic material, for example synthetic high polymers, and form a kind of brush.
  • the yarn end is laid between the pins 6.
  • the pins 6 are so close together that they exercise sufiicient friction on the yarn end to hold it when the spindle star-ts rotating.
  • the yarn end is fixed so tightly that the yarn breaks when an attempt is made to pull it loose.
  • FIGURES 2 and 3 This device is shown in FIGURES 2 and 3. It is built in a case 7, which is provided at its upper side with a yarn guiding groove 8. The bottom side is formed by a gripper 9 which is slidable transversely to the direction of the yarn 10. The yarn 10 is situated between the traveller below and the full tube that is taken upwards oif the spindle.
  • a cutter which consists of a knife 11 and a block 12 of elastic material, wherein a recess 13 is provided.
  • the cutter further comprises a clamping element 14, co-operating with a rib 15 on the upper side of the block 12, and a clamping element 16, co-operating with the fiat underside 17 of the block 12.
  • the block 12 is fixed to an operating rod 18, which can operate a number of cutters simultaneously.
  • the thread 3 is at first clamped between the clamping element 16 and the flat underside 17 of the block 12, as also between the rib 15 and the clamping element 14. After this the knife 11 cuts the thread; when block 12 moves still further the rib 15 gets clear of the clamping element 14; then the thread end which leads to the doffed tube, is loosed. The other end, however, is still being held between the element 16 and the underside 17 of the block 12. Now when an empty tube 2 has been placed on the spindle, the device is moved towards it and encompasses it with the recess formed in the gripper 9.
  • the gripper 9 is pushed back against the action of a spring 19, whereby at a determined moment the upstanding pin 21 ⁇ pushed against the finger 21 0f the arm 23 which is hingingly mounted on the axis 22 and is bent into a V, into the bottom part of which the yarn 10 is pulled by the top of the tube 2.
  • the pin 20 By the action of the pin 20 the arm 23 is moved towards the top of the tube; at the same time the block 12 is moved back so that the clamped yarn end comes loose and is laid between the pins 6 by the movement of the arm 23, which pins 6 then hold the yarn end. Then the device is moved back, the arm 23 is moved upwards by the action of a spring 24 and the spinning process can be started.
  • the device according to the invention comprises only a few parts which, in addition to this, need not comply with narrow tolerances. Therefore, the device here described is rather cheap to construct, which is a great advantage considering the number required.
  • a tube for a ring spinning frame having a substantially flat top end, a number of axially directed flexible pins provided on the top end, said pins being sufliciently close together for a yarn end laid between them to be held during the beginning of the spinning process.
  • An apparatus for connecting a yarn end to the top of a tube comprising a cutter of the type that can hold one of the yarn ends after the yarn 5 has been cut, means for operating said cutter, a hinging arm having a V-shaped end, and means for swinging said arm down on the top of the tube when the apparatus is moved towards the tube.
