Definitions

  • First and second threads the tensions of which must be e ualized are fed to their lace of rocessin from 30 F q r P P orelgn Apphcauon i Data respective first and second storage bobbins provided May 7, 1973 Czechoslovakia 3230-73 with braking discs Over rotating rollers situated on a bridge capable of oscillation.
  • the increased pull of the [g2] ⁇ I.S. Cll 242/156, 242/156.2 first thread in Case of an increased tension therein Flilt.
  • the invention relates to an arrangement for equalizing the tension of two supplied threads and is particularly suitable for use in apparatus for supplying binding threads to a device for reinforcing the borders of a fabric by a leno weave.
  • the arrangement according to this invention has two bobbins, supported on rotatable center rods arranged on a supporting disc, the bobbins being connected to the brake disc pins inserted into the faces of braking discs.
  • the bobbins When the binding threads are taken off from the bobbins, the bobbins, and therefore also the binding threads, are braked by wires encompassing the respective braking disc and disposed in circumferential grooves therein.
  • the first ends of both wires are together anchored on a hook shaped arm of a lever, the other arm of which cooperates by way of a neck formed on a screw head with oscillatable bridge.
  • a guiding roller is arranged on the bridge on each side of an imaginary straight direction of both binding threads in a distance differing at the place of contact of the binding threads with the guiding rollers from the distance of both binding threads at their imaginary straight direction toward the outlet eyelets.
  • the oscillating bridge is supported on at least two flat springs to move within a plane parallel with both planes in which the threads move in the course of their passage around the guiding and drawing-in rollers.
  • a pull spring is inserted between one end of each wire and its anchor thereby securing a constant tension of the wire.
  • the major advantage of the arrangement for equalizing the tension of two binding threads according to this invention is that it secures an equal relative tension of one thread with respect to the second thread, securing thus a better binding and quality of the border of the fabric.
  • the space required for housing the compensation means is relatively small.
  • the whole arrangement is simple and is easy to manufacture.
  • FIG. 1 is an elevation in partial section of the arrangement of the invention showing the guiding of the binding threads from the bobbins to the outlet eyelets;
  • FIG. 2 is a plan view of the whole arrangement
  • FIG. 3 is a view partially in section and partially in elevation of the rotatable support of a bobbin, the section being taken along line 3-3 in FIG. 2.
  • FIG. 3 An exemplary embodiment of the object of the invention is shown in the attached drawing, wherein the arrangement of the invention comprises a disc 1 supporting rotatable braking discs 2 and 3. As shown in FIG. 3, a rod 4 is inserted in the braking disc 2 to support and guide the bobbin 6, the bobbin and rod with the braking disc 2 being supported in antifriction bearings and turning together when taking off the binding thread 7. A pin 5 connects the bobbin 6 to the braking disc 2 to insure their joint rotation.
  • the second bobbin 8 carrying binding thread 9 is similarly constructed and supported.
  • a wire 11 encompasses a part of the circumference of the braking disc 2 lying in a groove 10 therein, the wire 11 is fixed at one of its ends to a hook shaped arm 12 of a lever 20, and is connected at its other end with a coil tension spring 13, which is suspended on a hook 14 of an adjustable anchoring means 15 provided with a position adjusting set screw 16 and a fastening screw 17.
  • a wire 18 is similarly arranged on the braking disc 3, and is anchored at one end. on a hook 14 and connected at its other end to a coil tension spring 19 which is suspended on the hook shaped arm 12 of the lever 20.
  • Lever 20 in turn is pivotally supported on a stub shaft 21 fixed on the supporting disc 1.
  • the second arm 22 of the lever 20 forms a fork, engaging into the neck 23 of the head of the screw 24, by means of which the end of a flat spring 26 is tightened to the bridge 27 through a washer 25, a second flat spring 28 being fixed to the bridge 27 by a screw 29 and washer on its opposite side.
  • the lower ends of the flat springs 26 and 28 are fixed to a strap piece 30 by screws 31.
  • the strap piece 30 is firmly connected with the supporting disc 1 by screws 32.
  • a holder 34 for thread guiding eyelet 35 and 36 is fixed at the center of the upper surface of the bridge 27 by a screw 33.
  • Guiding rollers 37 and 38 are provided on the opposite sides of the bridge 27, both rollers being rotatably supported on stub shafts 39 and 40 fixed to the bridge 7.
  • Rollers 41 and 42 for drawing-in the binding threads 7 and 9 to the outlet eyelets 43 and 44 are also rotatably supported on each side of the strap plate 30.
  • the arrangement operates so that in case of an increase of tension of one of the binding threads, for instance, of thread 9 on bobbin 8, the bridge 27 supported on delicate flat springs 26 and 28 deviates due to the increased pull of the binding thread 9 on the guiding roller 37 to the right, thus causing the head of the screw 24 with the neck 23 also to move to the right, thereby turning the fork of the arm 22 of the lever 20.
  • the hook-shaped arm 12 of the lever 20 is also turned, reducing the pull upon the wire 18 and accordingly reducing the braking force which brakes the bobbin 8, thereby causing a reduction of the tension of the binding thread 9.
  • the arrangement according to this invention can be applied to cases where an equal relative tension of two threads is required, and is particularly suitable for reinforcing of borders of fabrics by a leno weave.
  • Arrangement for equalizing the tension of two supplied threads taken off from individual bobbins comprising in combination a frame, two thread-carrying bobbins rotatably supported on the frame, a grooved braking disc affixed to each bobbin, braking wires received within the grooves of the respective bobbins, an-
  • choring means for one end of each braking wire affixed to the frame, a two-arm lever rotatably supported on the frame, one arm of said lever serving as an anchoring means for the second ends of both braking wires, a tension spring inserted in one end of each braking wire, a bridge supported for oscillation on the frame, a guiding roller for each thread on opposite sides of said bridge, a drawing-in roller for each thread on a support affixed to the frame, outlet eyelets for the thread fixed on the said support, and means pivotally connecting the bridge to the second arm of the lever so that turning of the lever in one direction by the movement of the bridge in a first direction increases the braking effect of a first wire on the braking disc of the first bobbin while decreasing the braking effect of the second wire on the braking disc of its respective bobbin, and turning of the lever in the other direction by the movement of the bridge in a second direction increases the braking effect of the second wire on the braking disc of the second bobbin while decreasing the braking effect
  • the mounting means includes at least two flat springs.
