Jacquard-harness of a weaving machine

#The invention relates to a Jacquard-harness of a weaving machine, in which the spacing of the heddles for adjusting the chosen material width are movable and adjustable preferably in the width of the machine, whereby the movable harness has in the area of the harness cords a plurality of series arranged comber boards, which are arranged one behind the other and having a guide bore per harness cord therein.

#It is common to weave names, trade names or trademarks into the fabric edges of certain fabrics. A name weaving machine (edge Jacquard) is used for this purpose. Such a machine can be compared with a Jacquard machine which is reduced in size, in which in most cases less than 100 sinkers are installed. The name weaving machine is arranged advantageously laterally in modern weaving machines, and the connection between the ends of the sinkers and the heddles is done by known harness cords. Such cords are guided in guide or comber boards in order to have at both ends a direction which is suitable with respect to the position of the sinkers and heddles. It is thereby often necessary to guide the cords around parts of the weaving machine, so that contact or wear is avoided.

#If on one and the same weaving machine fabrics of different widths are manufactured successively, it is necessary to adjust the heddles of the Jacquard part which effects the weaving in of the names or marks to the new fabric width or the new edge spacing. The normal position of the thread guides of the heddles is thereby supposed to remain unchanged, in particular with respect to their height from the crank shaft. In order to reach this goal, one has to newly tie, with a resulting high amount of work input, the harness cord lengths for the new conditions.

#One exemplary embodiment of the subject matter of the invention is illustrated in the drawings, in which:

#FIG. 1 illustrates schematically a loom having a laterally arranged name weaving machine operable on the Jacquard principle and a harness guide system to the laterally movable edge heddles;

#FIGS. 2A and 2B illustrate enlarged side views of two adjacent joints having comber boards in the harness guide system;

#FIG. 1 schematically illustrates a weaving machine 1A between its frame walls 1 and having a crankshaft 2 therein. A name weaving machine 3, for example, is arranged at the side of the weaving machine 1A. A harness guide system 4 extends from the name weaving machine to the left side (FIG. 1) of the not illustrated fabric which is being woven in the machine 1A and a harness guide system 5 extends to the right side of the fabric. The harness guide systems 4 and 5 each consist of rigid connecting rods 6, joints 7 which connect the rods 6 and guide or comber boards 8 which guide the harness cords. Only a single harness cord 9 is illustrated in FIG. 1. A bent or angled carrier rod 10 is connected to the end of each harness guide system 4 and 5 adjacent the harness cords. The free end of the carrier rod 10 is secured to an anchor plate 11. Elastic return elements 12 are secured to and extend between the anchor plate 11 and the schematically illustrated heddles 13. In addition, each heddle 13 is knotted together with or secured to a harness cord 9. The thread guides 14 are aligned at the same level and are spaced at a distance "a" from the crankshaft 2. The thread guides 2 are spaced at a distance "b" from one another, which distance corresponds to the distance from one weaving edge to the other on the not illustrated material.

#The carrier rods 10 for the entire harness are fixedly connected to the weaving machine in a manner not shown and can be adjusted with respect to one another to change their reciprocal distance from one another, so that the heddle package assumes the respectively desired distance "b," which corresponds to the distance between the weaving edges. Also individual connecting rods 6 can be fixedly connected to the weaving machine to fix the harness guide systems 4 and 5.

#FIGS. 2 to 4 illustrate a portion of the harness guide system in the area of the harness cords. The drawing illustrates two joints 7' and 7" which are arranged one behind the other and which are separated by rigid, that is bend-resistant, connecting rods 6". Reference numerals 6' and 6" identify the further adjacent connecting rods. Each of the rods 6 has at both ends thereof a bearing housing which receives a shaft member 15 to form several rotatable joints 7', 7" in the harness guide systems. Nuts 16 are used to lock the joints 7', 7" in an adjusted position. A comber board 8' or 8" is fixedly mounted on the shaft member 15.
