Definitions

  • the invention relates to a harness according to the preamble of claim 1 and a jacquard with a harness.
  • a jacquard weave generally consists of a jacquard device, a harness and a weaving machine.
  • the jacquard device contains shedding elements with a board which is connected to the weaving harness.
  • FIGS. 1 and 2 show a known embodiment of a harness.
  • the harness is mounted from the bottom up or from the top down and is therefore divided into a lower part and an upper part.
  • the lower part includes counter-pull elements and braid.
  • the upper part includes snap hooks, harness cords and an upper and lower choir board with through holes.
  • the harness cords per repeat are connected to the strings and arranged together in a through hole in the upper choir board and individually in through holes in the lower choir board.
  • the harness cords can be used as
  • the object of the invention is to improve a weaving harness in such a way that the disadvantages mentioned are eliminated and a considerable increase in the working speed of the weaving machine is made possible.
  • Fig.l a known Ausfu form of a harness
  • 2 shows a view of the embodiment according to FIG. 1 directed towards the underside of the upper choir board, from which the course of the harness cords can be seen
  • FIG. 3 shows a view of the connection of a jacquard device and an embodiment of a weaving harness according to the invention
  • Fig.5 measured the embodiment of the harness
  • Fig.6 measured the embodiment of the harness
  • FIG. 9 shows the embodiment of the harness according to FIG. 3, in which the harness cords are arranged in the rearmost row of all repeats and in the outer repeats of the second row.
  • the upper part of a harness contains a plurality of snap hooks 1 and harness cords 2 as well as an upper choir board 3 with through holes 4 and a lower choir board 5 with through holes 6.
  • the arrangement of the rows of holes in the upper and lower choir board is known.
  • a carabiner hook 1 is provided for connecting a circuit board 11 of the jacquard device to the weaving harness, and is designed in one piece.
  • the snap hook has a central section 12 and two sections designed as eyelets 13, which are elastically deformable in order to open the eyelets.
  • the connection point between the circuit board 11 and the upper eyelet of the snap hook forms the harness separation point.
  • the harness cords 2 are designed as a double cord with a loop 14 at one end and two sections, each of which is connected to strands of the lower part of the weaving harness.
  • an embodiment according to the invention is based on a step-by-step construction
  • the harness has four repeats I to IV. Only one harness cord 2 is arranged. For better understanding, the sections of the harness cord are referred to in the repeats I to IV below. Sections 1.1 and IV.1 of the double cord are routed together in the upper choir board 3 through the left through hole and in the lower choir board individually through the left through holes of the outside repeats I and IV.
  • FIG. 5 shows the harness, in which the sections 1.1 to 1.4 and IV.1 to IV.4 of the double cord m are arranged on the outside repeats I and IV in the lower choir board 5.
  • This arrangement is obtained by arranging the double cords in the upper choir board 3 m in the direction of arrow A in a sequence from left to right.
  • the sections arranged below lie in front of the sections arranged in advance.
  • sections II.1 and III.1 of the double cord for the internal repeats II and III are arranged in the same sense.
  • FIG. 7 shows the harness in which the sections m of the rear row of repeats I to IV are arranged in such a way that in the direction of arrow A a row of the arrangement of the harness cords in the upper choir board has an identical sequence of 3 m in the harness repeats in the lower choir board 5 are shown.
  • FIG. 8 shows a view corresponding to FIG. 2 of the course of the sections of the double cord in the embodiment of the weaving harness described above. Due to the continuous arrangement, sections 1.1 to 1.4, II.1 to II.4, III.1 to III.4 and IV.1 to IV.4 of the double cord are staggered, so that the sections guided in a hole in the upper choir board cross at least one of the sections led through the adjacent through-hole 4 in the upper choir board 3.
  • the staggered arrangement has the effect that the disadvantages of the known weaving harness mentioned are eliminated and has the advantages that the sections are guided against one another.
  • Fig. 9 shows the harness, in which the harness repeats of the back row and a harness cord of the front row are arranged.

Abstract

L'invention concerne un harnais à tisser qui comporte une partie supérieure pourvue d'une planche d'arcades à trous supérieure et d'une planche d'arcades à trous inférieure (3, 5), ainsi que des arcades (2) qui sont guidées ensemble dans les trous de passage (4) de la planche d'arcades supérieure (3) et individuellement dans les trous de passage (6) de la planche d'arcades inférieure (5). Ledit harnais comporte également un mousqueton (1) servant à relier les arcades de harnais au dispositif Jacquard, et une partie inférieure comportant des éléments de contre marche et des lisses. Les arcades de harnais sont disposées de telle sorte que dans le sens de trame (A), une rangée d'arcades disposées dans la planche d'arcades supérieure est formée selon une suite identique dans les rapports de harnais, dans la planche d'arcades inférieure, et que les sections passants dans un trou traversant de la planche d'arcades supérieure croisent au moins une des sections passant par le trou traversant voisin de la planche d'arcades supérieure. Grâce à cet agencement, la sollicitation des arcades de harnais est réduite et on peut obtenir une vitesse de travail élevée avec le métier à tisser.
