Definitions

  • ABSTRACT A method of drawing moving threads or yarns, preferably carpet yarns, into narrow channels and particularly threading channels of texturizing apparatus, in which method the yarn is drawn into said channel at a velocity of from 200 to 3,500 m/min by means of a wire loop passing through said channel, and at the same time or shortly thereafter the said yarn is severed at a point between said wire loop and a suction pistol adapted to take up the moving thread before it is drawn into said channel.
  • the invention also relates to apparatus for carrying out said method.
  • the present invention relates to a method ofdrawing moving threads or yarns into narrow channels, particularly threading channels of yarn-texturizing apparatus involving hot flowing media, preferably in stretch/texturizing processes, i.e., texturizing processes immediately following the stretching operation.
  • the invention LII also relates to apparatus for carrying out said method.
  • the solution of this problem is a prerequisite for combining the spinning process with said stretch/texturizing process.
  • the above object is achieved by drawing the yarn into said threading channel at a velocity of from 200 to 3,500 m/min and preferably from 800 to 2,400 m/min by means of a wire loop passing through said threading channel and by severing the yarn, at the same time or shortly thereaftere.g., between one hundredth and one tenth of a second thereafter -at a point between said wire loop and a suction pistol which had taken up the moving yarn before it was drawn into said threading channel.
  • Such channels generally have diameters of from 0.5 to 3 mm and in particular from 1 to 2 mm.
  • suitable wire diameters in said wire loop used in carrying out the method of the invention are from 0.2 to 0.5 mm depending on the diameter of the said threading channel.
  • the yarn is drawn into said channel with the aid of mechanical means for accelerating the wire loop, for example a compressed spring or a pneumatic piston.
  • mechanical means for accelerating the wire loop for example a compressed spring or a pneumatic piston.
  • a magnetic thread cutter is particularly suitable for severing the yarn.
  • the invention also relates to apparatus for carrying out said method, this being characterized by a wire loop fixed in a pin, a quick-grip chuck for accommodating said wire loop, a compression spring located in a barrel, and bolt carrying said chuck, a cocking lever for compressing said compression spring and an electromagnetic trigger for releasing the compressed spring.
  • FIG. 1 is a diagrammatic longitudinal section of the spring gun showing its essential parts
  • FIG. 2 is a diagram of the entire installation.
  • the spring gun consists of a guide barrel 11, a compression spring 12, a bolt 13, a quickgrip chuck 14 which is screwed to said bolt 13 and which is adapted to accommodate the wire loop 15 attached to the pin 16, a cocking lever 17 for compressing the compression spring 12 and an electromagnetic trigger 18 for releasing the compressed spring 12.
  • the end of the barrel ll remote from the chuck 14 is closed by means of a threaded cap 19.
  • a rubber ring 20 cushions the impact of the bolt 13.
  • the spring gun 10 is illustrated as being mounted on a trolley 25 together with a magnetic thread cutter 21, a thread guide 22 and a clamp 23 for the suction pistol 24.
  • the said trolley enables the apparatus of the invention to be readily moved to any texturizing station.
  • the velocity of the stretched yarn 28 (L220 f 67 dtex) is 800 m/min.
  • wire loop 15 and pin 16 are passed through texturizing unit 30 and placed in chuck 14 of spring gun 10.
  • the diameter of the threading channel is 1.2 mm and loop 15 consists of wire having a diameter of 0.3 mm.
  • the yarn On release ofthe compressed spring 12 and actuation of the magnetic thread cutter 21, the yarn is drawn through texturizing unit 30 by means of wire loop 15. Further transport of the yarn is effected by the medium flowing through the texturizing unit.
  • a method of drawing a moving yarn into a narrow channel comprising: drawing the yarn into said channel, while said yarn travels at a velocity of from 200 to 3,500 m/min, by means ofa wire loop passing through said channel;
  • An apparatus for drawing a moving yarn into a narrow channel comprising a wire loop attached to a pin as a yarn engaging assembly for insertion in said narrow channel, a quick-grip chuck for accommodating and holding said wire loop and pin, a bolt carrying said chuck within a guide barrel having comto receive a suction pistol.
