  • the improvement resides in [52] 0.8. CI ..242/164, 57/34 IT, 242/18 PW, h i flap is formed laterally of said main part and a 242/ 125.1 rounded leading nose is formed on said flap in an inclined and [51] Int.

  • turns of yarn initially laid-down on the bobbin are wound on a part of the bobbin axially offset from the main part thereof where themain body of yarn is to be wound, are called frequently as transfer-tail collectively among those skilled in the art.
  • the transfer-tail should be maintained in a wound condition while in shipping, transporting or storing until the bobbin is called for its practical use.
  • the transfer tail must be readily accessible and easily unwindable by those who are engaging in the textile trade for fabricating yarn stored on bobbins into fabrics or the like textile products.
  • the main wind then takes place; when it is completed, the ring is lowered to the wastetlspool position causing a widely spaced helix to be wound over the lower part of the package and then over the turns.
  • the bobbins is then lifted for doffing so that the turns unwind somewhat in opposite directions and one turn of the spiral becomes trapped in the slot in a band on the bobbin.
  • the yarn is then cut and the loose end is secured in the slot.
  • the adhesively stuck tab may be peeled-off only within several seconds after commencement of the bobbin rotation, when the tab-sticking adhesive is of a rather tacky nature. Even with use of a very tough adhesive, the stuck tab can remain in position on the bobbin for somewhat prolonged time period such as, for instance, 3 minutes upon starting of the yarn winding.
  • FIG. 1 is a perspective view of a conventional comparative bobbin structure carrying thereon a prior proposed yarnanchoring adhesive tab with a non-adhesive bearing edge portions made integral therewith.
  • FIG. 2 is an enlarged plan view of a conventional tab.
  • FIGS. 3 and 4 are similar views to FIG. 1, illustrative of two stages as met during completion of the bobbin structure according to this invention.
  • FIG. 5 is an enlarged plan view of an improved tab employable in the practice of the invention.
  • FIG. 7 is a perspective view, being illustrative of a substantially continuous, stepwise application of yam-anchoring tabs from a continuous base strip carrying a row of successive tabs preparatorily stucked on the base.
  • FIGS. 1 and 2 a comparative and conventional bobbin structure will be described briefly as a preparatory explanation of the background of the invention.
  • This conventional embodiment will serve well for completion of the bobbin structure carrying a mass of yarn either of S- or Z- twist.
  • a tab is shown at 10 in FIG. 2.
  • This tab 10 comprises a relatively elongated rectangular flexible strip made preferably paper or plastic material and comprises a main part 10a and end edge parts 10b and 100. Said main part 10a is desfined for adhering directly to the bobbin surface by means of an adhesive carried by said material, while the edge portions 10b and are free of adhesive.
  • the leading edge portion only functions and thus, the trailing edge portion can be dispensed with, if the bobbins are destined for winding a specific twisted yarn of S-mode or Z-mode, although the shown tab 10 is adapted for the both.
  • the bobbin II is coupled detachably and coaxially with a waste spool as shown schematically in FIG. 3 at 13. Then, the initial yarn end is wound several parallel turns on the waste spool and the latter together with the bobbin 11 is driven from a drive motor, not shown, for the formation of the parallel windings in its broader meaning and as shown 12b and 12c (see, also FIG. 3).
  • the yarn passes naturally over the stuck tab 10, as will be easily supposed from a glance at FIG. 3, although in FIG. 1 this conventional technique has been omitted from the drawing for simplicity.
  • the bobbin After completion of the bobbin winding, the bobbin, together with the wound-on yarn 12, is axially shifted upwards from the waste spool in the similar way as shown in FIG. 4 illustrative of an inventive embodiment.
  • an intermediate part of the parallel-wound initial turns or bunch windings of yarn invades into the air-gap below the leading flap and will finally be embedded in the adhesive existing between the main part 10:: of the tab and the bobbin surface,
  • FIG. 4 concerns with an inventive embodiment, the transfer-tail formation, the aforementioned bobbin-winding operation and the cutting-off operation of the free end yarn from the fixed tail on the bobbin are quite similar to the conventional art so far shown and described and therefore a glance at FIGS. 4 and 1 in succession makes it possible to understand more clearly the above description. It would be further clear that the aforementioned several drawbacks may be encountered with use of the conventional tab.
  • FIGS. 3-5 the first embodiment of the invention is shown, wherein the improvement resides substantially in a specific configuration of the tab, generally shown at 14.
  • This improved tab 14 comprises a main part 14a which carries adhesive on its back surface to direct towards the bobbin, and a flap part 14b which is free of adhesive and shaped preferably into substantially a triangle forming a one piece sheet together with the main part 140.
  • sheet of paper plastic sheet or metal foil may be used which has a substantial elasticity enough not to be fold back into twoply sheet when impinged while in its use with a heavy and strong counter fiow of air.
  • thickness of a paper material when used, No. 40-l00 (0.040.l mm thick) may be recommended to employ. If necessary, the paper may be mirror-coated with a plastic film according to the known technique before its practical use. Polyester" sheet or acetate film of No. 25-50 (0.025-0.05 mm thick) may preferably be used.
  • the flap must be so rigid to form a wedge-like air-gap when substantial part of the waste transfer tail has been slipped off from the bobbin as appearing during the removal of the latter from the waste spool of the spindle, as was explained hereinbefore in connection with the conventional technique. For the selection of the kind and dimension of the tab material, all these conditions must naturally be taken into account.
  • the critical zone between the main part 140 and the flap part 14b of the tab 14 is defined by substantially a straight line at Me which is in parallel to the longitudinal axis of the main part 140.
  • the nose 14d has a height, preferably 2-10 mm, which is shown atl'l" in FIG. 5.
  • the nose 14d is inclined upwardly and forwardly in the direction of the rotation of the bobbin on which the tab is to be adhered to, the leading and forwardly projecting distance T" being 2 mm or longer, preferably 4-8 mm.
  • the inclination angle of the longest side of the triangular fiap 14b must preferably be at least 15.
  • a modified tab 15 is shown at 15 in FIG. 6.
  • This tab 15 is shown at 15a which corresponds precisely to that shown at 14a in the foregoing first embodiment.
  • Reference 15c has the same meaning for 14c.
  • the flap 15b free of adhesive has been shaped into a tetragon having a forwardly and upwardly projecting rounded nose 15d which may have a more obtusely rounded tip end.
  • the longest side 15e of the tetragon may preferably have a rather smaller inclination than 15.
  • a tab as at 14 in FIG. 7 is supplied to the bobbin surface.
  • a mechanical supplying technique is shown in FIG. 7.
  • a number of tabs 14 are adhered in a row on an elongated tough tape 16 which is continuously moved at a relatively slow speed around a stripper 17.
  • the operation mode of the transfer tail of yarn on the bobbin surface is similar in principle to the conventional one referred to hereinbefore with reference to FIGS. 1 and 2.
  • the forwardly projecting rounded nose integral with the triangular or quadrilateral flap 14b or 15b, respectively, which is positioned not axially, but laterally of the adhesive-carrying main part of the tab relative to the advancing direction thereof will reduce substantially the air resistance in comparison with the case of conventional axial flap.
  • the conventional fiap will be peeled off from the bobbin surface only after several seconds when the empty bobbin is brought into rotation, provided that a weak viscous adhesive was used. Only with use of a strong viscous adhesive, the non-stripped period can be extended to about 3 minutes.
  • the strongly stuck tab with strong viscous adhesive may frequently be left on the bobbin upon subjected to peel-off operation in a textile producer, on account of tearing off the tab or, at least part of the adhesive remains on the bobbin. These residual tab portion and adhesive give rise to troubles in the course of further processing of the yarn.
  • the peel-off period can be extended to 30-40 minutes. This kind of extended peel-off period will be enough for the transfer tail fixation purpose. If a strong and viscous adhesive is used on the improved tab, the period will be further extended to 3.0-3.5 hours which means, however, only an experimental interest and in practice, use of such excessively sticky adhesive may preferably be avoided, as was briefly described hereinbefore in connection with the prior art.
  • the unsymmetrically designed flap will be deformed into a spiral configuration when impinged with the strong counter air current during the high speed rotational movement of the bobbin, which considerably reduces its air resistance in comparison with the conventional tab formed with a longitudinal and rectangular flap acting as a kind of a sail of a ship during the bobbin winding operation.
  • the conventional tab In order to avoid aforementioned easily peeling-off tendency, the conventional tab must be stuck on the bobbin surface with use of strongly viscous adhesive.
  • the tab naturally be peeled off at first from the bobbin surface manually and intentionally, for freeing the transfer tail.
  • an operator must grip the flap of the tab by his fingers ends and pull up.
  • the provision of the laterally arranged fiap employed in the invention will serve more effectively for this purpose than the case of the longitudinally arranged conventional tab.
  • the feeding direction must be axially of the bobbin in the case of conventional tabs which feeding mode is highly troublesome and uneconomical in comparison with use of the inventive tabs which enables a lateral feed of tabs realizable and provides a more effective and economical tab feeding mode.
  • the critical line between the adhesive-carrying main part and the adhesive-free flap of the tab directs circumferential in body of yarn, a transfer-tail of yarn and adhesive tab means securing said transfer tab to said bobbin, said tab means comprising an adhesive bearing main part and at least a non-adhesive bearing flap formed laterally of said main part and extending axially relative to said bobbin when said tab means is secured to said bobbin, said flap having a substantially oblique triangular configuration with the apex thereof extending beyond the leading end of said main part in the circumferential direction of said bobbin during rotation thereof.
