Definitions

  • the invention relates to a device for drying the size of glass fiber threads, which are wound on winding machines to form a winding, wherein a series of electrodes of different potentials are arranged around the winding, the distances from the winding surface and, transversely to the longitudinal direction of the threads / or whose electrical power can be regulated.
  • Drying devices of the type mentioned above have proven themselves from a technical and economic point of view for drying threads and, if appropriate, also fabric webs.
  • the object of the present invention is to design a device of the type mentioned so that the dry supported and the risk of electrical arcing on the electrodes can be reduced.
  • Electrodes are surrounded by a housing extending to the gap close to the winding, which is open to the surface of the winding and ir hot air is blown in at over 100 ° C under pressure.
  • the housing can advantageously consist of individual chambers connected in the manner of hinges, each of which covers an electrode group.
  • the housing and electrodes are then expediently adjusted together with the changing diameter of the winding.
  • each chamber can be provided with a separate hot air supply line, but it is also possible to introduce the hot air into the chamber itself through holes in the electrodes.
  • the thread 3 impregnated with size which consists of a large number of individual threads, runs in the direction of the arrow 2 into the winding machine and is wound here into a roll 1.
  • a plurality of rod electrodes 10 and 14 are distributed around the circumference of the winding 1 transversely to the longitudinal direction of the thread.
  • the over the entire width of the coil 1 extending rod electrodes 10 and 14 are alternately connected to different poles of the radio-frequency source 9 and are adjustable both in relation to one another and relative to the surface of the coil 1 in the direction of the double arrow 7.
  • Intensive and controllable drying of the thread 3 can be achieved due to the stray field in the longitudinal direction of the thread between the rod electrodes 10 and 14.
  • 0.5 to 5 kilovolts per cm should be recommended as the field strength and about 10 MHz to 30 MHz, preferably approx. 15 MHz, as the frequency.
  • the power of the high-frequency source 9 can be adjusted in accordance with the temperature measured with a temperature meter 6.
  • the electrodes 10, 14 are surrounded by a housing 4, which consists of individual chambers 41 connected to one another in the manner of hinges 8, each of which covers an electrode group 10, 14.
  • Each chamber 41 is connected to a separate hot air supply line 51, via which hot air 5 of over 100 ° under pressure, e.g. 1.5 atmospheres.
  • the injected hot air 5 flows around the electrodes 10, 14 and flows out through the gap between the chambers 41 and the surface of the roll 1.
  • the hot air both heats the electrodes and prevents moisture and / or sizing from reaching the electrodes. At the same time, additional drying of the winding surface is achieved.
  • a sensor 11 which detects the diameter of the winding 1 and which acts on a central control device 12.
  • This central control device 12 gives control commands to the individual drives 13, which move the individual electrodes 10, 14 along the curved or straight guideways 15 so that their distance 16 to the surface of the winding 1 and the mutual distance 17 always remain the same or at least approximately the same .
  • the gap s between the surface of the winding 1 and the chambers 41 mechanically connected to the electrodes also remains approximately constant, so that the hot air with the moisture components can escape through this gap.
  • the housings themselves are made of flexible insulating material, so that they can follow the movements of the electrodes to a certain extent and at the same time cause electrical insulation between the individual electrodes of different potentials.
  • the arrangement described above can not only be used for drying the size of glass fiber threads, but can also be used e.g. be used when drying textile fibers or the like.
