Definitions

  • Jet looms Shuttleless weaving looms with a pneumatic picking mechanism, so-called jet looms, are known, in which the weft is inserted into the shed by means of an air stream produced by a suitably arranged nozzle.
  • the weaving width of such looms is relatively small, being limited by the carrying capacity of the air stream entraining the weft. Due to mixing of the air of the jet with the surrounding air the power of the picking stream decreases, said stream being not capable to entrain the weft any further.
  • the weft particularly its leading portion, does not fly smoothly or in a straight line, but forms loops; the leading end of the weft is thus deflected from the axis of the picking movement and the weft thread may easily be caught by the warp threads extending at right angles to the direction of iight of the weft. If the weft is caught in the warp threads, loops may easily be produced leading to faults in the fabric.
  • the shed is covered at the outside from both sides with plates in order to produce a channel facilitating the flight of the weft through the shed.
  • Attempts have also been made to achieve a similar result with two troughs provided outside the shed, which, when approaching each other form a picking channel.
  • the sides of both troughs are shaped in the manner of a gear toothing, the teeth of the upper trough engaging the gaps in the lower trough so as to effect a continuous closure of the sides of the channel.
  • warp threads are inserted at the same time so as to permit the opening of the warp.
  • a device is further known in which the beat-up reeds are provided with two extensions approximately perpendicular to the plane of the reed which together with the plane of the reed form a trough guiding from three sides the air stream and having for its intended purpose to keep the flying weft out of contact with the warp threads.
  • a disadvantage of this arrangement is on the one hand its dependence on the reed, because when the density of warp threads is changed, the whole reed, the production of which is difficult, has to be changed, and on the other hand the shape of the trough from the aerodynamic point of View i.e. as far as the guiding of the air stream is concerned, is not perfect.
  • the trough being open at one side, the air stream can expand at this side; this leads not only to a rapid reduction of the stream velocity, due to a diminishing ow of air, but also to a change of direction of the air stream, which becomes inclined under the influence of a component of the velocity of air escaping through the open wall of the trough.
  • the device according to the invention permits to increase the weaving width of shuttleless weaving looms with pneumatic picking mechanism/jet-looms/by the arrangement of a suitable picking channel for guiding the weft through the shed.

  • FIG. 7 is a section of the picking comb of FIG. 2, with details added.
  • a shaft 1 revolving with the revolutions of the weaving loom carries a crank disc 2 with a pin 3.
  • a connecting rod 4 converting the circular motion of the crank pin 3 in an oscillatory reciprocal motion of swords 5 by the intermediary of pins 6.
  • the swords 5 are mounted for rocking movement around a pivot 7.
  • Fixed by screws 14 to the beam 9 is a so-called condenser or comb 15 consisting of teeth 16 and spacers 17 (FIG. 2) inserted between the teeth and rigidly connected into one unit by means of two bolts 18.
  • the teeth 16 are widened in their upper portion and provided with an aperture 20 (FIG. 3) with a slot 21.
  • the aperture 20 which is in its greater part of circular shape blends with the slot 21 by a continuous transition portion 22.
  • a conical recess 23 is apparent which forms a tapered cross section of the aperture in the direction 24.
  • the tooth 16 is of chiefly flat formation and along its entire periphery, which engages the shed 26, i.e. where the gaps in the comb are located, the circumference of the teeth is sharpened to an edge 25.
  • FIGS. 5 and 6 show a hollow tooth made for example of thinwalled metal tubes by soldering.
  • the tooth in the shown design consists of two attened tubes 29, 30 and an inlay 31 which are connected together e.g. by soldering in points 34, 35 so as -to form a unit corresponding in principle to the main functional dimensions of the aforesaid tooth 16, shown in FIG. 3. Air is supplied to the teeth through the tubes 33.
  • the device represented in FIG. l is shown on the one hand (with full lines) with the reed 11 in its rear extreme position and on the other hand (with dotted lines) with the reed in its forward extreme position at the moment of beat-up, when the whole condenser or comb 16 emerges from the warp, rocking below the plane 27 of the shed.
  • a gap a is provided between the fabric and the upper contour of the air condenser or comb 16, said gap being suicient for the location of temples (not shown) and other auxiliary members.
  • a compressor 74 shown in FIG. 9 passes a compressed air through pipe 73 into a nozzle 71.
  • the tip of the nozzle is located so as to direct a stream of air through the passage formed by the recesses 20 in the guiding teeth means 16.
  • the weft is picked by means of a pneumatic apparatus (not shown) through an air nozzle of a known design by the influence of an air stream.
  • the air nozzle has to be placedV on the loom so that the axis of the air stream projecting therefrom should, at the moment of picking, pass through the channel Ziifof Ithe condenser or comb 16.
  • the air stream entraining the weft is then guided and directed by the channel in the condenser or comb and cannot expand freely to the sides, its kinetic energy being thus maintained and utilized to a greater distance than with a free current in the atmosphere.
  • the directing influence on the air stream of the condenser is assisted by the conical transition portion 23 or recess which forms an inlet to the various apertures of the teeth (FIG. 4).
  • the conical transition portion 23 or recess which forms an inlet to the various apertures of the teeth (FIG. 4).
  • the air does not penetrate through the gaps 19 between the teeth out of the channel, but on the contrary air is sucked in from the l shed in downward direction under simultaneous closingV of the shed.
  • the weft, lying in the channel meets the warp threads during this movement, it slides out of the picking channel through the slot 21 during further movement.
  • the reed 11 then beats up the weft to the fabric 2S in a normal way.
  • the condenser or comb 16 enters the shed again through the lower half of the warp and, after reaching the rear extreme positionV the described process is repeated.v
  • a condenser or comb carrying out a longitudinal lmovement in thedirection of the weft is used with preference.
  • the condenser is shifted in longitudinal direction through a small distance so that the warp threads, lying between the teeth, may be changed when the next submersion into the warp takes place.
  • the formation oflongitudinal strips in the fabric is thus prevented, which otherwise would be caused by the warp threads being pushed apart always in the same place by the teeth of the condenser.
  • a further advantage is a lower consumption of air and therefore also of driving power, because due to the air stream being giuded through the condenser channel, an expansion of the stream is avoided, such expansion involving also a drop of its efficiency in guiding the weft.
  • the guiding of the weft is therefore more reliable, it being also possible to achieve with the same consumption of air greater weaving Vwidths than with the pneumatic picking by a free air stream.
  • the air condenser shields also the air stream, entraining the weft, from outer infiuences, because irregular currents and whirls occur in the Vicinity of the picking path of the weft, upon movement of the reed and other devices, said currents and whirls having a disturbing eifect on the smooth flight of the weft.
