Definitions

  • the invention relates to a weaving loom for production of combined structures of the ground and gauze weave comprising a device for control of at least a triad of systems of warp ends and a loom reed with lamellas, between which there are spaces for passage of warp ends, while warp ends are separated to at least three systems (2, 3, 4) out of which at least two systems are guided into the basic distributing means realising the motion necessary for creating the shed for weft insertion and mutual interlacing of warp ends and at least one is guided through the deflecting bar into the guiding means of rotating warp ends.
  • the woven fabrics with combination of the ground (or derived) weaves and gauze weave are of a specific mechanical properties, especially the weave strength, but they also have specific pattern-decoration possibilities.
  • the combined structures were applied especially at production of curtains in combination of Jacquard and gauze weave.
  • the known devices for production of woven fabrics with combined weave utilise the heald harnesses to control the warp ends. It is common, that the harness of the ground weaves is positioned closer to the warp and the gauze harness is positioned closer to the weaver.
  • heald systems for creating of gauze weaves brings the main disadvantage in the form of a low working speed. This disadvantage still has not been solved at the machines for combined weaves. Though increasing of working speed upon creation of purely gauze weaves is known by usage of the healdless systems, e. g. according to the CZ PV 2003-2887 , but these systems are for the time being designated exclusively for weaving of non-combined purely gauze weave.
  • DE 616 709 C discloses the weaving loom for production of combined structures of the ground weave and gauze weave, when the interlacing point of the ground (plain) weave is wound round by the gauze thread.
  • This machine comprises a couple of heald shed devices at which basically no separation of warp systems exists, which enhances occurrence of undesired force interactions in the form of mutual contacts between the threads which results in lower maximum achievable quality of the fabric.
  • Another disadvantage is insufficient power of the machine from the point of view of fabric production.
  • US 4 429 772 A discloses the weaving loom for production of combined structures of the ground weave and gauze weave when the interlacing point of the ground (plain) weave is wound round by the gauze thread.
  • the gauze shed device into which the threads of the gauze system are brought from independent bobbins situated outside the basic machine, is of a needle type and the warp ends of the gauze system are guided through the bar, but the plain shed device is of a heald type and through the gaps between the healds there must pass the warp ends of the gauze system.
  • This arrangement does not show a sufficient separation of both warp systems in the section bar - backrest, by which the undesired force interactions in the form of mutual contacts between the threads are increased, which results in lower maximum achievable quality of the fabric.
  • Another disadvantage is necessity to use an independent feeding device of threads of the gauze system including independent bobbins, etc.
  • the goal of the invention is to enable usage of the healdless weaving systems for weaving of combined weaves, especially the combinations of the ground and gauze weave.
  • the goal of the invention has been achieved by the weaving loom for production of combined structures of the ground and gauze weave, whose principle consists in that.
  • the basic distributing means are formed of carrier beams with needles and/or half healds, at the same time the carrier beams are coupled with individual electronically controlled drives, and the guiding means of rotating warp ends comprises needles with eyes for guiding the rotating warp ends.
  • Fig. 1 shows an axonometric view to the two warp ends and 1 weft thread interlaced in the basic plain weave and whipped by one gauze thread
  • Fig. 2 axonometric view to the means creating the combined structure of ground and gauze weave
  • the Fig. 3 a section through the weaving loom with arrangement of means for production of combination of a ground and gauze weave.
  • the weaving loom 20 for production of combined structures of the ground and gauze weave comprises the warp beam 21 or several warp beams from which in a known manner are brought the warp ends which are separated into three or more systems 2 , 3 , 4 .
  • At least the first system 4 of warp ends, which creates so called rotating threads is fed via the deflecting bar 18 into the guiding means 13 of rotating warp ends, which comprises the needles 12 with eyes for guiding the rotating threads.
  • the guiding means 13 with needles 12 is coupled with the drive and it carries out the horizontal motion in the z direction. Motion of the guiding means 13 in the z direction is synchronised with the motion of further described basic distributing means 15 realising the motion necessary to perform the shed for weft insertion and for mutual interlacing of warp ends.
  • the drive of the guiding means 13 is preferably formed of the device among the specialists called "electronic cam". From eyes of needles 12 the individual threads of the first system 4 of warp ends, i.e. the rotating threads are guided into the spaces between the dents of the loom reed 11, like this arrangement is described at the known solution for production of purely gauze weaves being comprised in the CZ PV 2003-2887 .
  • the system 2 , 3 of the ground warp ends must have at least two subgroups, which are guided into the weaving means realising the motion necessary to create the shed for weft insertion and for mutual interlacing of the warp ends.
  • the systems 2 , 3 of the basic warp ends are guided into the basic distributing means 15 with carrier beams 152 , 153 and fastened by the flat needles 14 or the half healds.
  • the means 15 are coupled with the not represented motion mechanism, which in an interval of a certain weaving cycle of the machine, e.g.
  • each thread from the first system 4 of the warp ends i.e. each thread from the rotating threads is whipped around the corresponding couple of warp ends from the system 2, 3 of warp ends.
  • Motion of the basic distributing means 15 is secured by individual electronic engines or servomotors controlled in such a way that the means 15 could interlace the warp ends of the systems 2, 3 with the weave that corresponds to the number of means 15 on the weaving loom.
  • the produced woven fabric is being drawn-off by the draw-off mechanism 5 with the take-up rollers and it is wound up to the cloth roller 22 .
