Definitions

  • the invention relates to a yarn brake with a rotatably mounted drum and means for adjusting the torque of the drum.
  • a yarn brake for textile machines in which a single thread is at least partially wound around a ball-bearing brake roller, which is rotatably mounted.
  • the braking torque of the thread brake can be adjusted with a set screw.
  • a separate thread brake is required per thread. In this case, a uniform adjustment of the thread tensions for the threads can not be guaranteed because each thread brake must be set individually.
  • a yarn brake with a rotatably mounted drum is known. From a bobbin, a thread is pulled off, which is wound around the drum. The drum is braked by a brake pad, whereby the torque exerted by the brake pad on the drum can be adjusted with a set screw.
  • the yarn tension of a plurality of yarns can be adjusted by means of a plurality of yarn brakes of the abovementioned type.
  • a plurality of drums rotatably mounted on an axis, wherein a thread is wound around each drum.
  • each drum is assigned a separate brake pad.
  • Each brake pad is assigned a separate adjusting screw, with which the torque acting on the respective drum or the thread tension of the thread running through the corresponding drum, can be adjusted.
  • the yarn brake includes a plurality of drums, each drum having a separate brake pad and a separate screw.
  • Thread brakes are also known from U.S. Patent 4,324,607.
  • the thread tension can be reliably adjusted with the thread brakes known from the prior art, they have a complicated construction.
  • the object of the invention was to provide a yarn brake, with a variety of threads with a control variable to constant and mutually simultaneous thread tensions could be set in a simple manner.
  • the object is solved by the claim 1 ..
  • the tension of several threads can thus be reduced or increased by a common drum on the drum outlet relative to the drum inlet.
  • the threads are preferably wound several times per receiving groove around the drum.
  • the torque of the drum or a plurality of drums is preferably adjusted synchronously by a common drive element, for example a belt drive, chain drive or gear train.
  • one means for adjusting the torque can be provided per yarn brake, for example, a clutch / brake combination with electric motor.
  • the grooves extend arcuately in cross section, wherein the diameter of the drum at the thread inlet is greater than the thread outlet. A multi-wound in the receiving groove thread is urged in this way from the thread inlet to the thread outlet, so that it does not come to overwinding and a defined spring tension is built up in the outlet.
  • a thread brake 1 in a perspective view, which is essentially formed of a cylindrical drum 2 and a drive wheel 3 with means 3 for adjusting the torque.
  • the means for adjusting the torque may for example be a clutch / brake unit with electric motor.
  • As a transmission element belts, chains or gear train can be used.
  • a plurality of receiving grooves 4 are provided, which extend around the outer circumference of the drum 2 and are each spaced from each other in the direction of the drum axis x.
  • the receiving grooves 4 extend around the outer circumference of the drum 2 around.
  • a thread 5 is received, which is looped several times around the drum 2 and inserted into the receiving groove 4.
  • a yarn 5 is driven or braked by the yarn brake 1, wherein the yarn tension of all yarns 5 of a yarn brake 1 are set uniformly.
  • the drum 2 is mounted on one side, so that the threads 5 can be easily inserted into the grooves 4.
  • FIG. 2 shows an embodiment of the yarn brake 1.
  • the drum 2 is in this case designed as a drum shaft 6 mounted on both sides, which is mounted at both ends of the drum shaft 6.
  • a drive wheel 3 At one end of the drum shaft 6 is a drive wheel 3, which cooperates with the means 3 for adjusting the torque.
  • the receiving grooves 4 are again provided at a distance from each other, which extend around the outer periphery of the drum shaft 6 around.
  • FIG. 3 shows a drum 2 in side view.
  • the grooves 4 here have a curved profile.
  • the thread inlet 7 of the thread 5 is provided in the region of the larger diameter of the receiving groove 4 and the thread outlet 8 in the smaller diameter, so that the thread 5 moves axially upon rotation of the drum 2 in the direction of the smaller diameter of the receiving groove 4.
  • over-windings are avoided and it can form a uniform yarn tension.
