  • the leading thread The traversing thread guide ends by an electrical coil back and forth, with the coil in a magnetic field is arranged and the traversing movement of the Traversing thread guide for laying the thread on a Cross-wound package generates and controls.
  • DE 43 35 089 describes a device to control the thread tension, by means of which the thread tension gradually increased or decreased to a desired value can be used to compensate for an increased Unwinding tension.
  • the device for controlling the thread tension is part of an automatic winding device. To the effort that when using such a device in everyone individual winding unit of the winding machine would be required avoid an output signal to control the Thread tension obtained on a specific spindle and one Many other spindles of the winding machine due to this Output signals controlled.
  • One that works as a calculator Clamping device with a pair of cooperating comb-shaped Parts has a solenoid that operates via a linkage and an eccentric the degree of engagement of the combs in the thread course and thus the measure of the contact angle of the thread with respect to Comb teeth sets.
  • DE 195 44 202 describes a device for tensioning yarn known with which the thread tension to a setpoint is settled.

  • magnetic bearings instead of the roller bearings, hydraulic bearings or air bearings are used come.
  • the swivel lever can, as far as possible, be very be made of light material and therefore also that Reduce the moment of inertia and the regular inertia.
  • a thread 1 is drawn from a payout spool 2, passes through a balloon breaker 3, a control device 4 for control the thread tension of the running thread 1, a yarn cleaner 5 as well as a fixed thread guide element 6 before it is on a rotating cheese 7 is wound.
  • the for the Winding of the package 7 required traversing movement is generated by a so-called reverse thread roller 8, which by a motor M is set in rotation and at the same time the Circumferential drive for the package 7 causes.
  • Control device 4 and yarn cleaner 5 are with a Control device 9 connected.
  • FIGS. 2 and 3 show a control device 4 in which a Swivel lever 10 can be seen, which is by means of a roller bearing 11 and a shaft 12 is mounted.
  • the pivot lever 10 is off material made as light as possible so that a low Moment of inertia when swiveling and sufficient Strength of the pivot lever 10 is realized. As a material Where possible, plastic is used.
  • the pivot lever 10 carries on a lever arm 13 firmly connected to it Thread tensioning elements 14, 14 ', 14' '.
  • the thread 1 runs zigzag around the thread tensioning elements 14, 14 ', 14' 'and the stationary at not shown for reasons of simplification Housing of the control device 4 arranged Thread tensioning elements 15, 15 ', 15' ', 15' ''.
  • the coil 18 is together with the lever arm 17 in one Air gap 49 pivoted between the yoke 19 and Magnets 20 and 21, which in turn are fixed to the yoke 22 are connected, is formed.
  • the air gap 49 has one constant gap width and is influenced by a magnetic field flowed through, the magnetic field lines by arrows 23 are indicated.
  • the yokes 19, 22 are separated by the yokes 24, 25, 26 connected.
  • the through yokes 19, 22, 24, 25, 26 running field lines are not for reasons of clarity shown.
  • the magnets 20, 21 are permanent magnets trained and arranged in different poles.
  • the Pole orientation of the magnets 20, 21 is indicated by the designation indicated with S and N.
  • the coil 18 is energized via lines 27 and 28.
  • Lines 27 and 28 are through bores 29, 30 in the shaft 12 and are thereby subjected to only slight movements.
  • Energizing the coil 18 is a torque on the Swing lever 10 applied, passing through the thread guide forces exerted on the thread tensioning elements 14, 14 ', 14' ' Balance of forces and a corresponding Swivel position of the pivot lever 10 is controlled.
  • Fig. 4 shows a further embodiment of a control device according to the invention.
