Definitions

  • This invention relates to apparatus for compensating for tension variations in linearly advancing thread-like elements consisting, for example, of paper or textile fibres, or threads of glass, synthetic material and the like, hereinafter referred to as thread, and which are advanced linearly into processing machines, such as machines for texturing yarns, or for twisting, coning, knitting and weaving.
  • processing machines such as machines for texturing yarns, or for twisting, coning, knitting and weaving.
  • the threads arriving from delivery means do so frequently under conditions of rather widely varying tensions; but it will be understood by those persons skilled in the art that for optimum processing, the threads ought to be introduced into the machine under as regular a tension as possible.
  • a known device of this kind consists of two diScs between which the yarn is passed, and a spring is employed to adjust the pressure on the discs. After leaving the discs, the thread is passed through an opening in a lever which is connected with the spring, the lever being drawn from a position of equilibrium when the state of original tension is varied, whereby the pressure of the spring and therefore also the pressure exerted on the discs is varied.
  • my device comprises a support having surface means upon which the thread is received and delivered along a desired linear path, a guide member engageable by the thread and moveable relatively to the support in response to variations in the thread, and means cooperating with the support surface means to apply a braking force to the advancing thread.
  • the support is cylindrical in configuration and has an annular surface at its upper end over which the yarn passes, and the guide member engageable by the thread is slideable within the cavity of the cylindrical support.
  • cylindrical support and annular surface means shall be understood to include surface means and support the configuration and cavity of which are round, square, polygonal or of any convenient configuration.
  • the guide member may be equipped with an arm extending through the annular surface means and through the braking means, and a stop may be located at the remote end of the arm adapted to engage the braking means to increase the braking force on the thread upon a predetermined drop in the tension therein.
  • Apparatus according to my invention provides exceedingly rapid reactions resulting from sudden variations of tension in the thread and compensatively adjusts the tension in the thread in advance of the processing machine.
  • FIG. 1 is a top plan view of one embodiment of my invention
  • FIG. 2 is a cross-sectional view taken along the lines 22 of FIG. 1;
  • FIG. 3 is an elevational view of the guide member
  • FIGS. 4, 5 and 6 are similar to FIGS. 1, 2 and 3, respectively, but illustrate a different embodiment of the invention.
  • FIGS. 1 to 3 there is shown a cylindrical support 1 which may be fabricated of die cast aluminum and which is enlarged at its upper region and recessed to receive a generally annular bearing member 2 of porcelain or the like having a polished outer surface whichfollows a curved conic path between horizontal and vertical surfaces.
  • An annular polished porcelain disc 3 is positioned on the upper surface of the bearing member 2, and is freely maintained in that position by means of four guides 4 extending upwardly of the support 1 and spaced ninety degrees apart.
  • An annular disc 5 is positioned atop the disc 3 and serves as a weight, this disc 5 also being maintained in position by the guides 4.
  • a guide member 8 is slideably disposed within the bore or cavity In extending longitudinally of the cylindrical support 1 and has a polished curved surface 6 and a slot 12 communicating with an opening 7 therein.
  • An arm 10 extends upwardly from the member 8 through the opening 9 in the annular disc 3 and a wider opening in the disc 5 and is equipped with an enlarged stop 11 at its upper end.
  • the member 8 has a hollow cylindrical piston 13 extending downwardly from its lower end and a weight 14 is secured in the bottom of the piston by means of a set screw 16 which protrudes outwardly of the piston and fits within a slot 17 in the lower end of the support 1 to act as a stop for upward movement of the assembly.
  • the thread 15 moves from a delivery member such as a bobbin (not shown) and passes between the bearing member 2 and the disc 3, into the opening 7 by means of the slot 12 to bear against the surface 6 and out between the bearing member 2 and disc 3 to a processing machine.
  • the weight of the member 8 and the piston 13 draws the thread 15 downwardly until its frictional resistance on the surface 6 and on the surface of the bearing member 2 corresponds to the tens-ion set by the disc 3 which may be of suitable weight.
  • the curved surface of the bearing member 2 provides an increasing line of cont-act between that surface and the thread as the member 8 moves downwardly; and conversely, the line of contact, and therefore the friction between the two is reduced as the member 8 moves upwardly.
  • the members 8 and .13 are raised until the upper surface 8a of member 8 abuts against the lower surface of the disc 3, and upon a further increase in tension, lifts the disc 3 away from the thread 15. If the processing machine stops, the thread will be maintained under tension because of the loading of the disc 3 and the member 8 and piston 13.
  • FIGS. 4 to 6 there is shown similar apparatus to that already described except that the apparatus of FIGS. 4 to 6 has no arm or stop .11, and the disc 3 has no central open- 'ing.
  • a lower piston stop 19 is mounted from the support 1 by means of a stationary bar 18.
  • the piston I13 sinks until the frictional resistance on the surface 6 and the surface of the member 2 correspond to the thread tension adjusted by the load provided by the disc 3 and any additional load members 5.
  • the piston is made to fit closely within the support cavity; and for this reason and because the disc 3 (FIGS. 4 and 5) has no central opening, a slight vacuum is created in the support cavity in zone 29, as the piston drops, thus urging the disc downwardly and further loading the thread 15.
  • I contribute a device of the class described which is capable of reacting exceedingly quickly to compensate for tension variations in linearly advancing thread. It will be appreciated that interchangeable parts such as pistons and braking discs of different weights may be employed. Additionally, spring or magnetic means may be used to load the guide member.
  • Apparatus for compensating for tension variations in linearly advancing threadlike elements comprising a cylindrical support having annular surface means upon which the threadlike element is received and delivered along a desired linear path, a guide member engageable by the threadlike element within a cavity extending longitudinally of said cylindrical support and moveable vertically relatively to said support in response to variations in tension in the threadlike element, and means cooperating with said support surface means to apply a braking force to the advancing threadlike element.
  • stop means are provided limiting movement of said piston-like member in response to a reduction in the tension in the threadlike element.
  • Apparatus for compensating for tension variations in linearly advancing threadlike elements comprising a cylindrical support having annular surface means upon which the .threadlike element is received and delivered along a desired linear path, a guide member engageable by the threadlike element within a cavity extending 1ongitudinally of said cylindrical support and movea'ble vertically relatively to said support in response to variations in tension in the threadlike element, means cooperating with said support surface means to apply a braking force to the advancing threadlike element, said guide member including an arm extending through said annular surface means and said braking means, and a stop at the remote end of said arm adapted to engage said braking means to increase the braking force on the threadlike element upon a predetermined drop in the tension therein.
