Definitions

  • the invention is for a device for slightly tensioning yarn which is wound by a rotating driven pipe or other body in successive loops around the standing reel of a yarn accumulator and where a rocking disc causes the formed loops of yarn to be displaced toward the free end of the reel, from which point the yarn is wound off so that it can be led to any device whatsoever for the processing of the yarn.
  • the rocking disc must therefore overcome the friction between the yarn loops and the reel during the displacement of the yarn loops on the reel.
  • the tension of the yarn wound around the reel must be limited. This is achieved by allowing the circumference of the reel to diminish along its length.
  • the reel consists of longitudinal rods, these rods are provided on the parts on which the yarn is wound with a conic part, causing the yarn pushed up the reel to be gradually and slightly detensioned in order to facilitate the displacement of the yarn loops along the reel.
  • a disadvantage of this however is that there is a danger that when the detensioned yarn is wound off via a guide over the head of the reel, several loops of yarn may be taken off at once thus giving rise to defects and yarn breakages.
  • the reel is mounted so that it slants upwards in the yarn accumulator and a guide ring is mounted freely around the longitudinal rods of the reel, which guide ring serves to guide the yarn being wound off the reel, on which guide ring several yarn tensioners mounted in a conical arrangement are provided where the ends which are attached to the guide ring protrude outside the circumference of the reel and where the other ends are located inside the reel, while several guide rails are mounted in the reel parallel to the longitudinal rods of the reel, and guides are provided on said guide ring and yarn tensioners, which guides are meant for the movement of the guide ring with the yarn tensioners longitudinally over the reel along the guide rails.
  • the slanted positioning of the reel and the weight of the guide ring itself with the yarn tensioners mounted in a conic arrangement causes the yarn to be tensioned slightly at the place where it is wound off the reel, so that the yarn is wound off over the guide ring more in the radial sense and less in the longitudinal direction and without problems.
  • the reel 1 is mounted so that it slopes upwards in the yarn accumulator 2, where known means are provided for keeping the reel immobile.
  • This reel consists of several longitudinal rods 3, one end of which is fixed in a reel bearer 4 which is kept immobile and where the other end of which is attached to a ring 5.
  • a guide ring 6 is provided over the longitudinal rods of reel 1 which can move freely in the longitudinal direction along the reel, where the diameter of the guide ring 6 is greater than that of the reel 1 formed by the rods 3.
  • Several yarn tensioners are mounted conically on the guide ring 6, which tensioners consist in this case of rods 7.
  • the rods 7 may also consist of plates or other elements.
  • a number of guide rails 9 are mounted in the reel 1 parallel to the longitudinal rods 3 of the reel 1.
  • Two guides set an angle to one another run over each guide rail such as guide rollers 10 the spindles of which are attached to arms 11 which are radially attached to the guide ring 6 and the supporting ring 8.
  • the conically arranged rods 7 which constitute the yarn tensioners position themselves by their own weight beneath the loops of yarn, so that the yarn, which at this point is wound off virtually radially over the guide ring 6, is again slightly tensioned.
  • the guide ring 6 with the yarn tensioners 7 will move in accordance with the quantity of yarn wound on the reel and will tension the yarn slightly at every point of the reel.
  • the yarn tensioners may consist of rods 7, plates or other elements and the guides 10 for the movement of the guide ring and the yarn tensioners may consist of rollers, wheels, bearings or sliders.
