Definitions

  • the present invention relates to a combination with a spindle rotor of a two-for-one twisting machine having thread outlet means in said rotor with a thread storage disc structure which is characterized primarily by the provision of two discs, one arranged below the other in axially spaced relationship to each other while strip means having an outer surface of high wear resistant material are arranged between and connected to said discs.
  • the said strip means includes a first portion of annular contour extending around said rotor in radially spaced relationship thereto, and also includes a second portion extending from said first portion in radial direction inwardly toward said rotor within the range of said thread outlet means in said rotor to form thread exit passage means for the thread leaving said thread outlet means.
  • the present invention relates to a thread storage disc for two-for-one twisting spindles.
  • the so-called thread storage disc forms a part of the spindle rotor.
  • the thread which passes from above through the hollow shaft of the spindle in downward direction moves radially through a thread exit passage out of the thread storage disc and then rotates together with the spindle rotor in the form of a balloon around the stationary bobbin while moving upwardly to the winding-up bobbin while passing through a centrally arranged thread guiding member.
  • the yarn leaving the thread storage disc Prior to detaching itself from the thread storage disc, the yarn leaving the thread storage disc normally embraces the thread storage section of the thread storage disc at least by 180, frequently by more than 360.
  • the frictional retaining force thus exerted by the yarn in looping engagement with the thread storage disc acts in a direction opposite to the centrifugal force of the yarn while passing through its balloon-shaped path and acts almost without inertia in an equalizing manner upon the thread tension because the magnitude of the looping of the yarn around the thread storage disc adjusts itself automatically in conformity with the speed and the thread tension and in conformity with the coefiicient of friction.
  • the thread exit passage as well as the thread storage section of the thread storage disc are subjected to a considerable wear by the passing yarn, and this wear will after a period of time actually cause grooves to appear in the material of the thread storage disc, unless such disc is made of a particularly surface wear resistant material.
  • FIG. 1 illustrates partly in section and partly in view a thread storage disc according to the invention with a cylindrical thread storage section, said disc being mounted on a spindle pipe.
  • FIG. 2 is a section through a modified thread storage section with a conical flare in upward direction.
  • FIGS. 20, 2b and 20 respectively illustrate sections through modified cross sectional shapes of a thread storage section.
  • FIG. 3 is a partial section in the plane of the exit passages of a thread storage disc according to FIG. 1.
  • FIG. 4 illustrates the total of the parts of the thread storage section according to FIG. 3 but on a reduced scale with regard to the latter.
  • FIGS. 5 and 5a respectively illustrate parts of a thread storage section of modified thread storage discs.
  • the arrangement according to present invention is characterized primarily in that the thread storage disc comprises an upper deviating flange disc and a second smaller disc axially spaced from the first disc and connected to the spindle rotor, the thread storage section being formed by at least one strip of a material having a high surface wear resistance. This strip extends along both discs while leaving free the thread exit passages.
  • material of high surface wear resistance there may be employed for instance eloxated aluminum, chrome-plated steel sheet, bimetal, one or more layers of synthetic materials, such as polytetrafiuoroethylene, sheet metal with a layer of synthetic material, as for instance ethylene glycol adipinic acid polyester synthetic material, such as the aforementioned materials, with a layer for instance of chromium or nickel, or strips with ceramic coating or cover.
  • synthetic materials such as polytetrafiuoroethylene
  • sheet metal with a layer of synthetic material, as for instance ethylene glycol adipinic acid polyester synthetic material, such as the aforementioned materials, with a layer for instance of chromium or nickel, or strips with ceramic coating or cover.
  • the thread storage section according to the present invention may be composed of two strips of high surface Wear resistance the ends of which are (2 bent radially inwardly to form the thread exit passages.
  • the thread storage disc has two thread exit passages extending along a diameter line, one of said passages being employed for the thread exit.
  • these ends form the lateral surfaces of the thread exit passages so that these passages will have the same surface property or the same wear resistance as the thread storage section which is formed by the two strips.
  • thread storage sections of different cross section and diflerent surface property can be obtained.
  • the strips may be bent cylindrically.
  • the strips may be so bent that the thread storage section flares upwardly in a conical manner.
  • the strips are bent so as to form a polygon.
  • the strips of the above mentioned three embodiments may have their outside provided with axial ribs or the like, thereby improving the adherence of the thread passing therearound prior to the detachment of the thread from the thread storage disc.
  • axially directed wear resistant bodies may be arranged by means of which the yarn is deviated from the radial direction into the tangential direction with regard to the thread storage disc.
  • the strips may have a longitudinal trough-shaped section.
  • FIG. 1 comprises a spindle rotor 1 having mounted thereon an upper deviating fiange disc 2 with a hub 3.
  • the outer marginal portion of disc 2 is in customary manner bent upwardly.
  • spindle rotor 1 has mounted thereon a second disc 4 with a hub 5.
  • disc 4 has a considerably smaller diameter than disc 2.
  • the outer marginal area of second disc 4 has a groove 6 in which is inserted a strip 7 forming the storage section of the thread storage disc.
  • This strip 7 may be composed of two individual strips 7a, 7b, the ends of which within the range of the thread exit passages 8 may, in conformity with FIGS.
  • FIG. 2 shows a modification inasmuch as strip 7 of .FIG. 1 has been replaced by a strip 7c which flares in upward direction in a conical Way.
  • strip 7c which flares in upward direction in a conical Way.
  • the strip 7 of FIG. 1 has been replaced by a strip 7d, 7 and 7g respectively which form a more or less deep groove or trough. More specifically, according to FIG. 2a the said trough 7d has a semicircular cross section and has its outer surface covered by a layer 14 of a different material.
  • the said layer of different material may consist of synthetic material, such as polytetrafi'uoroethylene, or may form a layer of a metal, such as chromium or nickel.
  • the trough according to FIG. 215 has a flat angle cross section whereas the trough of FIG. 2: has a hyperbolashaped cross section.
  • strips 7 are bent so as to form a portion of a polygon.
  • the arrangement of FIG. 5a corresponds to that of FIG. 5, while, additionally at the ends of said polygonal section, strip 7 is provided with axially directed ribs 11.
  • strips 7 As material for strips 7 is preferably employed aluminum or steel sheet while at least the outer surface is provided with a particularly good wear resistant surface.
  • This surface when employing aluminum, may be eloxated, and when employing steel, may preferably be hard chromium plated.
  • This wear resistant layer is also provided at the ends 9 of strip 7 Within the range of the thread exit passages 8.
  • a thread storage disc structure which includes: a first disc having an outer peripheral thread deflecting flange and being mounted on said spindle rotor for rotation therewith, a second disc arranged below said first disc and in axially spaced relationship thereto and being connected to said rotor for rotation therewith, said second disc having an outer diameter less than the outer diameter of said first disc, and strip means having an outer surface of a high wear resistant material, said strip means extending between and being connected to said first disc and said second disc and including a first portion of annular contour extending around said rotor in radially spaced relationship thereto and also including a second portion extending from said first portion in radial direction inwardly toward said rotor within the range of said thread outlet means in said rotor to form thread exit passage means for the thread leaving said thread outlet means.
