Definitions

  • This invention relates to a thread tensioning device for a textile machine, consisting of a fixed and a movable jaw. Each jaw has outwardly directed extensions and the extensions of one of the jaws extend between those of the other jaw and the thread is guided between the extensions according to a zig-zag line.
  • These thread tensioning devices are generally used when Warping yarns which form strong loops.
  • the braking-01f of the yarn is necessary to obtain a certain tension in the same when it is warped on the beam.
  • Grape-yarns however, have the disadvantage of showing strong loops with the slightest tension differences. Therefore it is of importance that each tension difference which can occur during warping be directly neutralized.
  • the best yarn brake which can serve for this purpose is that in which the thread is braked-off between jaws according to a zig-zag line.
  • the tension in the thread is greater before it reaches the yarn brake, e. g. when the thread reaches the end of the cone or the velocity of the warping machine is altered.
  • the yarn brake is provided with a thread tensioning device in such a way that the brake action can be controlled as the tension in the thread is altered.
  • An embodiment according to the invention utilizes a lever constructed as a bell-crank lever pivotally connected to the movable jaw, and the long arm of the lever is provided with an eye and the short arm bears against the stationary jaw.
  • Fig. 1 is a view in perspective of a part of a yarn brake provided with a tensiom'ng device according to the invention
  • Fig. 2 is a side view of a yarn brake with tensioning device.
  • the yarn brake consists of a pivotal upper jaw or lid I and a stationary jaw 2.
  • thread guiding members 3, for example of porcelain, are arranged, and which are provided with slots or holes 8.
  • Similar members 4 are connected to the jaw I and extend between the members 3 of the stationary jaw.
  • a tension controlling device serves to avoid this; in that it is connected to the jaw i by means of the bracket it.
  • This tension controlling device consists of a bell-crank lever with arms 32 and I3 pivotally mounted on the bracket i5.
  • the arm It has a thread eye I I which is spaced in a relatively large distance beyond the normal path of the thread 9 which passes from right to left through the device as viewed in Fig. 1. Owing to this the thread obtains a large loop.
  • the arm It bears on a part I4 of the stationary jaw.
  • the arm I3 which is substantially shorter than the arm it, will bear on the part I4 and, acting as a lever, lift the lid I, owing to which the braking action is reduced.
  • the tension controlling device will seek a central position or remain in its closed position, i. e. in the position in which the jaws exert their normal brake action.
  • a thread tensioning device for a textile machine comprising a stationary and a movable jaw. extensions on each said jaw, extensions on one of said jaws being extendable between those of the other said jaw, thread being guided between the extensions in a zig-zag line, a bell-crank lever pivotally connected to the movable jaw, one arm of said lever having an eye therein, the other arm of said lever bearing against the stationary jaw, said movable jaw in working position bear ing on an arm of said lever, said lever being actuated by thread passing through said eye and on increase of thread tension said lever pivoting and said arm bearing against the stationary jaw forcing said jaws apart.
