Definitions

  • the invention relates to a device for control of warp threads in a weaving machine for production of leno fabrics comprising on a batten positioned reed with gliders among which are fed pairs of warp threads, where one of which is a part of a stationary warp threads system and the second is a part of a rotating warp threads system, while in the movement direction of the warp threads during weaving is in front of the reed positioned a guiding device of rotating warp threads coupled with an independent drive and a guiding device of stationary warp threads coupled with an independent drive, the warp threads of the rotating warp threads system are before entering the guiding means of the rotating warp threads deflected in the direction out of the stationary warp threads system using a guide member positioned in the frame of the machine.
  • Leno fabrics exhibit specific properties given by the construction of the binding point, where the particular cross lapping and consequently interlacing of the warp threads necessary for fixation of weft in the fabric is created by mutual whipping of a pair of warp threads around the introduced weft.
  • the position of the weft is in every weft cycle always over the same one and below the same second warp threads system, where the warp threads do not interlace it by mutual rotation of upper and lower position but so is done by mutual whipping of rotating warp threads around stationary warp threads. This is why among wefts in leno fabric can be found gaps and these fabrics are suitable as industrial fabrics, backing cloths for carpets and the like.
  • Each warp threads system is led into own guiding means, whose arrangement and method of drive is different from known weaving machines.
  • WO 98/07913 is the stationary warp threads system fed through a guide member into the eyes of needles positioned on vertically reversibly convertible heald shaft, on which is positioned also the guide member. Nevertheless, guide member blade is situated over the weaving level.
  • Rotating warp threads system is led in skewed slots of another vertically reversibly convertible heald shaft, which is in the movement direction of the warp threads positioned in front of the shaft frame with the needles.
  • the rotating warp threads system led into a direct slot of another heald shaft going along the entire width of the warp, while before this heald shaft the warp threads system passes through compensating rollers mounted on next heald shaft.
  • Each of the heald shafts, through which passes the rotating warp threads system are vertically reversibly convertible and are positioned below the weaving level.
  • DE 612 805 is know device for control of warp threads in a weaving machine for production of leno fabrics comprising on a batten positioned reed with gliders among which are fed pairs of warp threads, where one of which is a part of a stationary warp threads system and the second is a part of a rotating warp threads system, while in the movement direction of the warp threads during weaving is in front of the reed positioned a guiding device of rotating warp threads coupled with a drive and a guiding device of stationary warp threads coupled with a drive.
  • the warp threads of the rotating warp threads system are before entering the guiding means of the rotating warp threads deflected in the direction out of the stationary warp threads system using a guide member positioned in the frame of the machine. After this deflection the rotating warp threads come through the jacquard heddle system (f), heald shaft (g), needle system (h) and the reed system (i).
  • a device for control of warp threads in a weaving machine for production of leno fabrics whose principle consists in that the guiding means of rotating warp threads consists of a system of needles fitted with eyes positioned on a needle bar mounted horizontally reversibly convertibly on the machine frame on means situated over the weaving level and the guiding means of stationary warp threads consists of a bar fitted with openings and which is vertically reversibly convertibly mounted on means situated below the weaving level.
  • FIG. 1 is the axonometric projection of basic elements of the apparatus
  • Fig. 2 is a detail of a reed and guiding means of warp threads from Fig. 1
  • Fig. 3 is a cross section of the machine with both warp threads systems and with guiding means of warp threads and a batten with the reed in a picking position
  • Fig. 4 is a cross section of the same part of the weaving machine as in Fig. 3 in a beat up position.
  • a warp beam 1 From a warp beam 1 are warp threads 2 drawn-off in a well-known manner and they are divided in a rotating warp threads system 21 and a stationary warp threads system 22 .
  • the stationary warp threads system 22 is led through a back rest 3 to a guiding means 4 of stationary warp threads 22 consisting a bar 41 fitted with openings 411 through which are led stationary warp threads 22 , which further go through the gaps among gliders of the reed 51 , which is positioned on a batten 5 into a binding point 23 , where they become a part of a fabric 200 .
  • the bar 41 with the openings 411 is positioned vertically convertibly, which is in Fig. 1 shown as a double arrow II and coupled with a drive using means situated below the weaving level, which is composed of the horizontal plane fitted through the binding point 23 .
  • the bar 41 with the openings 411 can be replaced for instance by a heald shaft with healds.
  • Rotating warp threads system 21 is from the point of splitting from the stationary warp threads system 22 led through a guide member 6 into a rotating warp threads 21 guide means 7 , which consists of a needle bar 7 , in which are mounted needles 72 with eyes 721 , in which are led rotating warp threads 21 .
  • the needle bar 71 is on the frame of the weaving machine mounted using leaf springs 711 convertibly in a horizontal position in the direction of the double arrow III and is coupled with electronic cam formed by a synchronous electromotor 73 with a governor.
  • the drive of the needle bar 71 is composed of a separate motor, which is with the drive of the stationary warp threads 22 guiding device 4 coupled only with an electronic connection.
