Definitions

  • the circumferential groove is filled with the windings of the underwinding coil and the slots allow the lead yarn to be woven into and about the groove before forming the underwinding coil to prevent loose ends and rotation of the underwinding coil in the groove.
  • the lead yarn is moved up and down to be interwoven between the slots and groove and guided into place by the ring and ring coil.
  • This invention relates to an apparatus and process for winding yarn. More particularly, the invention relates to an apparatus and process for winding yarn on ring spinning and ring twisting frames, and, still more particularly, for underwinding the yarn on these frames.
  • the invention provides an apparatus and process for underwinding a yarn on a spindle after a major portion of the yarn has been wound on the bobbin.
  • the apparatus of the invention includes a spindle having an underwinding element positioned around the p riphery thereof below the plane at which a yarn is wound on a bobbin and above a take-up section on the spindle.
  • the underwinding element is formed with a groove peripheral of the spindle to accommodate an underwinding coil and with a series of substantially perpendicular slots communicating the groove with the exterior of the underwinding element to permit entry and exit of a yarn into the groove.
  • the slots are disposed to either side of the groove to permit passage of a yarn in either direction out of or into the groove.
  • the underwinding element is formed with a peripheral groove below the groove for the underwinding coil.
  • This second groove is inclined upwardly to the axis of the spindle and serves to form a take-up section below and within the plane of the underwinding coil groove.
  • Still another embodiment of the apparatus includes an underwinding element having a take-up section which is positioned above the underwinding element and which communicates with an underwinding groove in the element through a series of slots.
  • the slots on the underwinding element are arranged above and below the underwinding groove in either of an aligned manner or a circumferentially offset manner.
  • the process of the invention includes the steps of initially taking-up of the trailing portion of the yarn not wound on the bobbin and winding that portion on the underwinding element on the spindle mounting the bobbin.
  • the yarn is first wound on the spindle in a plane coincident with the groove of the underwinding element, the yarn passing through one of the slot in the element. Thereafter, the yarn is moved into a second plane coincident with the take-up section of the spindle, again passing through a communicating slot in the element.
  • the yarn is wound in this second plane for a very brief period of time and is then returned to the first plane where it again is wound into the underwinding groove to complete an underwinding coil.
  • the underwinding coil which is thus formed is compact and intimately joined to the underwinding element.
  • the yarn can be severed at a suitable point to permit the bobbin to be removed from the spindle while the underwinding coil remains on the underwinding element of the spindle in a neat clean manner. This facilitates the automatic doifing of the bobbins.
  • FIG. 1 illustrates a front elevational view of a spindle of the invention, partially cut-away, on a spinning frame;
  • FIG. 2 illustrates a top view of only the underwinding element of the spindle of FIG. 1;
  • FIG. 3 illustrates another embodiment of an underwinding element with an inclined take-up groove below an underwinding groove
  • FIG. 4 schematically illustrates a partial development of the circumferential surface of the underwinding element of FIG. 1 with an outline of the lead yarn and underwinding coil;
  • FIG. 5 illustrates an enlarged fragmentary view of the underwinding coil of FIG. 4 after coverage of the lead yarn
  • FIG. 6 illustrates another embodiment of an underwinding element in a fragmentary partially cut-away view
  • FIG. 7 schematically illustrates a partial development of the underwinding element of FIG. 6 with the lead yarn during take-u
  • FIG. 8 schematically illustrates a partial development of an underwinding element having circumferentially offset slots on either side of an underwinding groove
  • FIG. 9 schematically illustrates a partial development of another underwinding element.
  • FIG. 10 schematically illustrates a partial development similar to FIG. 4 with a modified coiling pattern.
  • a spindle 2 of a plurality of spindles situated on a spinning frame is driven by a common drive belt 1 in a known manner.
  • a tube 3 is positioned on the spindle 2 for the Winding of a yarn 4 thereon and a vertically reciprocal moving ring 5 is positioned concentrically to the spindle.
  • a traveller 6 is mounted on the ring 5 to travel around the ring 5 circumferentially of the spindle to lay the yarn on the tube 3.
  • a ring rail 7 is positioned under the ring 5 in order to transmit vertical motion to the ring 5.
  • An underwinding element 9 is integrally formed on the spindle wharve 8 contacted by the drive belt 1 below the tube 3.
  • the element 9 has a peripheral groove 10 for accommodating an underwinding coil 11 and a pair of limiting flanges 12, 13 which serve to define the walls of the groove 10.
  • a plurality of recesses or slots 16 are formed over the peripheral edge of the underwinding element 9 to pass through the limiting flanges 12, 13 and to radially penetrate the bottom of the groove 10 (FIG. 2).
  • the slots 16 are in substantial parallel alignment with the axis of the spindle 2.
  • the ring rail 7 is lowered to form the underwinding coil 11.
  • the yarn which is being guided toward the inside by the traveller 6 comes into contact with the limiting flange 12 and, depending on the respective speeds of the flange 12 and the traveller 6, the yarn is caught by one of the recesses or slots 16.
  • the ring rail 7 continues to descend the yarn 18 moves into the plane E of the groove 10 and becomes deflected at the edge 14 (FIG. 4) of the underwinding element 9 while beginning to fill the groove.
  • the thread is caught again in a recess or slot 16 while deflecting twice at edges and 19 and wound up in the plane E of a take-up section 20 of the spindle 2.
  • the yarn is wound up on the take-up section 20 for a very brief period only.
  • the wind up length of the yarn on the take-up section 20 is to be just large enough to permit automatic and complete removal of the taken up yarn length from the spindle 2 during a subsequent mechanical dofling of the underwinding coil 11.
  • the yam is wound onto the take-up section 20 over a length that is less than the entire circumference of the section with the ring rail 7 remaining in its lowermost position for a correspondingly short period of time.
  • the number of windings in the underwinding coil depends upon the deceleration of the ring spinning or twisting frame motor upon braking (eg. through an exterior braking assembly) As a rule braking of the motor occurs during the lowering of the ring rail 7. For economic considerations it is naturally appropriate to keep the number of windings as low as possbile since such material constitutes waste. This object is readily achieved since the lead yarn is systematically bound in on the underwinding element 9 and need subsequently be covered by only a few circumferential windings in the groove 10.
  • the coiling pattern on the underwinding part 9 obviously depends on the wind-up speed of the yarn and the chronologic behavior of the ring rail 7.
  • the resultant coiling pattern substantially corresponds to that shown in FIG. 10. This provides for a weaving-in and tightening of the lead yarn 21 by deflecting it several times into portions 22-25 of the underwinding element 9 and permits intimate joining of the lead yarn with the spindle by means of the coil 11 proper.
  • the yarn is torn off slightly above the underwinding element 9, approximately at R (FIG. I) and the yarn 4 including tube 3 is removed from the spindle 2.
  • the ring rail 7 is raised in a known manner into initial spinning position and the machine reactuated. This results in the entry of the yarn 32 (FIG. 4) at the end of an underwinding coil into any recess 16 of the upper limiting flange 12 for passage from there onto the freshly inserted empty tube.
  • an underwinding element 33 is upwardly and inwardly recessed at an angle to form a groove 35 beneath the underwinding groove 34.
  • the space between the plane E coincident with under-winding groove 34, and the plane E coincident with the adjoining take-up section 36 is considerably reduced.
  • the circumferentially arranged recesses or slots 37 coming from the take-up section 36 penetrate deeper into the underwinding element 33 than the bottom of the groove 34. This arrangement makes it possible to maintain the angle a between the plane E and the path of the yarn from the groove 34 to the take-up section 34 very small.
  • the yarn upon re-entry from below into the groove 34, the yarn is positioned profoundly on the bottom of the groove 34 and is therefore also satisfactorily covered by the subsequent underwinding coil 11'. This is very important for the subsequent mechanical dotfing of the coil in that one can prevent a premature severing of the lead yarn holding the coil 11' which severing would result in a sliding of the coil in the groove 34 making positive dofiing impossible.
  • the coiling pattern resulting in this underwinding element 33 substantially corresponds to that shown in FIGS. 4 and 10.
  • a spindle 2' is integrally formed with an underwinding element 9' having a groove 10 defined by a shoulder 45 of the spindle 2' and a single limiting flange 12'.
  • a take-up section 46 is provided on the upper part of the underwinding element 9' and, as above, a series of peripherally spaced recesses or slots 16 are formed in the lmiiting flange,' shoulder, groove 10' and take-up section 46.
  • the yarn returns immediately into the plant E to complete the underwindingi'coil 11'.
  • the lead yarn is first woven-in into parts of the underwinding section by subjecting it to a plurality of deflections, and then covered. Each deflection represents an increase in fraction and hence, even with few terminal windings, trouble free restarting of spinning and favorable conditions for mechanical dofling of the coil 11" are created.
  • a coiling pattern can be produced to efiect a greater number of yarn deflections by circumferentially displacing the recesses 40 and 41 of the upper and lower limiting flange with respect to each other rather than arranging these recesses in facing relation.
  • the invention described creates the prerequisites indispensable for the automating of ring spinning.
  • the woven-in and tightened lead yarn of the underwinding coil is no longer detached as a result of centrifugal force, thereby eliminating entangling during spinning restart and guaranteeing a clean spinning process all around.
  • the systematic weaving-in and tightening of the lead yarn is actually the factor that makes it possible to achiece positive and trouble free dofiing of the underwinding coil by means of a simple underwinding element.
  • the underwinding coil can neither rotate nor open up by centrifugal force in the groove, rather, following the spinning-on of the lead yarn for a new cop, it can be dotfed at any time without any difliculty from the outside to the inside.
  • the number of terminal winding-s can also be kept to a minimum, which is in the interest of achieving low material wastes.
