Definitions

  • ABSTRACT In a shuttleless loom, a plurality of sheds are laid one over another in a direction of a shedding motion such that the adjacent yarn systems of the shed cross each other between a reed and a fell of cloth and each pick of weft is carried through the shed with fluid jet and a common reed. Fabrics having even qualities from fabric to fabric can be woven with a minimum required floor space according to the present invention and productivity and economy of a loom have been widely improved.
  • the present invention relates to weaving with a shuttleless loom and particularly to weaving a plurality of fabrics with one reed by forming a plurality of sheds one over another in a direction of a shedding motion in a shuttleless loom which projects weft into the shed with liquid jet.
  • a loom requires a given floor space (the sum of the floor space occupied by the loom itself and the area occupied by aisles between looms required for opeations, maintenance and repair for the loom), and the necessary floor space for producing a given amount of fabric affects very widely productivity and economy of the fabrics. Even if the number of looms is increased, the necessary floor space per loom is often increased instead of decreased since the size auxiliary equipment becomes larger.
  • beating force of a reed to the cloth fell corresponds to the distance between a rocking shaft, which is a fulcrum of the beating motion and the point of beating. Therefore, if the distance between the adjacent cloth fells is great, uneven qualities from fabric to fabric are likely to occur. However, as it was essential that the shed be kept appropriately wide open, it was difficult to reduce the uneven qualities from fabric to fabric under a certain limit. It was very difficult to repair warp yarn breakage of the lower shed or find defects of the lower gray cloth.
  • a plurality of sheds are vertically laid one over another in a direction of a shedding motion in a shuttleless loom.
  • Each shed is arranged such that it is kept open wide enough for picking; the distance between cloth fells is as small as possible; and the adjacent yarn systems cross each other between the reed and the cloth fell at a time when shedding is greatest in order that uneven qualities of fabrics from fabric to fabric may be prevented.
  • a primary group of warp yarn drawn out of one or more than one warp beam is divided into subgroups of warp yarn by the aid of a plurality of back rests.
  • Each warp yarn subgroup forms its own shed and the adjacent yarn systems are arranged such that they cross each other between a reed and a cloth fell.
  • Each pick of weft is carried through each shed by fluid jet and beaten up into the cloth with one common reed to produce pieces of fabric having no uneven qualities and minimize the neces sary floor space of a loom per piece of fabric.
  • a plurality of sheds are formed in one loom with the use of a heddle assembly where a plurality of rows of heddles are disposed side by side in one and the same harness frame and the eyelets of each heddle are arranged so as to agree with the warp line or with that of a heddle assembly where a plurality of eyelets are provided in one heddle.

  • FIGS. 2 and 3 are elevations showing the shedding state of the present invention.
  • FIG. 4 is an elevation of a warp yarn tension control device.
  • FIG. 5 is a diagram disclosing variations of length of warp yarn due to shedding.
  • FIG. 6 is an elevation showing a heddle assembly in which each heddle having one eye is attached to one harness frame.
  • FIGS. 7 to 9 are elevations of a heddle assembly in which two heddles are attached to each harness frame.
  • FIG. 10 is an elevation of a heddle assembly in which two eyes are provided in each heddle.
  • FIG. 11 is an elevation showing a section for the removal of a liquid and the winding-up of fabrics.
  • FIG. 12 is a perspective view, partly cut away, of a liquid-removing tube.
  • warp yarn group A drawn out from a warp beam 1 or from warp beams 1 and 1' is divided into warp yarn subgroups B and C by the aid of two back rests 2 and 3, which are caused to form a shed, respectively with a heddle assembly 4 and divided into warp yarn systems B-l, B2, C-1, and C-2.
  • a pick of weft is inserted with nozzles 5 and 6 and beaten up with a common reed 7 to produce gray cloths D and E at cloth fells 8 and 9.
  • the gray cloths D and E are caused to tightly adhere to each other on a supporting member 10 and taken up onto a cloth roller 17 via a first liquid-removing tube 11, a press roller 12, a friction roller 13, a press roller 14, a liquid-removing tube and a guide roller 16.
  • the warp yarn group A is divided into two warp yarn subgroups B and C with the aid of the two back rests 2 and 3.
  • the warp line of the warp yarn subgroup B connecting the back rest 2 with the supporting member 10 approaches gradually to the warp line of the warp yarn subgroup C connecting the back rest 3 with the supporting member 10 towards the dirction of the respective cloth fells 8 and 9 from the respective back rests 2 and 3, until at least the two warp lines converge with each other at the supporting member 10.
  • the subgroups B and C are respectively caused to form an opening with a heddle assembly.
  • the lower yarn system C-2 of the upper shed and the raised yarn system 8-1 of the lower shed cross each other at an intersection point P.
  • the intersection point P is arranged so as to stay between cloth fells 8 and 9 and a reed 7.
  • the distance between the cloth fells can be minimized and an opening space sufficient enough for picking can be maintained. It is very advantageous for picking to have an appropriate opening near the intersection point P. It is clearly seen that consistent and level weaving is possible with the formation of sheds as shown in the figures.
  • intersection point P falls on the line connecting the centers of the nozzles 5 and 6 or is located slightly nearer the reed than the line. It is clear that positioning the intersection point at the front of the reed is possible only in a shuttleless loom but impossible in a shuttle loom which requires provision of a race, etc. at the front of a reed.
  • the distance between cloth fells be as small as possible, say, 0 to 15 mm.
  • the distance between cloth fells be as small as possible, say, 0 to 15 mm.
  • to a broken warp end of the raised yarn system 8-1 of the lower shed is tied a repair end and the tied repair end is pulled to the cloth fell 8 through the heddle and the reed without interfering with picking from the nozzle 6.
  • warp yarn tension control will be described below.
  • the warp yarn group A is divided into two warp yarn subgroups B and C by the aid of the two back rests to form two sheds in a direction of a shedding motion
  • warp yarn tension should be controlled somehow or other because Without control of tension, tension to warp yarn forming each shed differs from each other, result ing in fabric quality being different from fabric to fabric and loose warp yarn causes poor picking.
  • the back rests 2 and 3 be not laid one over the other vertically but be staggered away from or towards the cloth fell in view of each access of yarn and the height of a loom. However, with this arrangement yarn tension becomes uneven all the more. Referring to FIG.
  • K and L denote positions of the back rest, I a cloth fell and H an apex at the time of maximum shedding.
  • m and TL show warp lines.
  • the two warp lines do not really overlap, but are laid one over the other for simplicity of explanation.
  • I is the foot ofa common perpendicular from H and shows that tlgsize of the sheds is equal to each other.
  • the difference in the length of warp yarn .IH FIR at opening of a shed and the length of JR at closing is greater when the distance is smaller between the cloth fell and the back rest. It is understood from this fact that when a plurality of back rests are in use, one single tension control device is not sufficient enough for warp yarn tension control.
  • the tension of a primary warp yarn group drawn out of a warp beam is adjusted with a main back rest, and the tension of a warp yarn subgroup further divided therefrom is additionally adjusted with a second back rest.
  • an individual back rest may be provided for each warp yarn subgroup for adjusting each yarn tension or one of the warp yarn subgroups may be adjusted with a main back rest and the other subgroup may be adjusted with a second back rest.
  • FIG. 4 shows the latter case.
  • the warp yarn group A unwound from a warp beam 1 is divided into the warp yarn subgroups B and C after it passes through a guide roller 18 and the primary back rest 2.
  • the subgroup C is pulled toward the backrest via the second back rest 3.
  • the primary back rest 2 is rotatably mounted on a lever 20, the lever being connected to a tension control device 21 through a roller 19 with the pivot at the guide roller 18.
  • the second back rest 3 is rotatably mounted on a lever secured to a shaft 23.
  • One end of a lever 24 is secured to the shaft 23 and the other end is connected to a tension control device 26 through a roller 25. Accordingly, the back rest 2 is adjusted with the tension control device 21 and the back rest 3 by the tension control device 26; thus the tension of the warp yarn subgroup B is adjusted by the tension control device 21 and that of the warp yarn subgroup C by the tension control device 21 and further sensitively by the tension control device 26.
  • adjustment by the tension control device 21, that is, adjustment by means of the back rest 2 lies within the range suitable for the warp yarn group B. It is possible to provide an individual back rest for each of the warp yarn subgroups B and C after adjustment of tension has been made to a certain extent with a primary back rest.
  • a plurality of sheds are to be formed and if one harness frame with one heddle having one eye makes a shedding motion, two times as many heddles and harness frames as the number of sheds are required. For instance, when two sheds are formed, four heddles and four harness frames are required. Now consideration should be given to relations between the number of harness frames and the size of a shed. As the number of harness frames increases and the distance between the cloth fell and the harness frame on the side of the back rests becomes greater, the desired shed cannot be obtained unless the size of a shed is made greater. However, if the size becomes greater, warp yarn comes into contact with harness frames and soiled, broken, bruised or chafed warp yarn will occur. And if the number of heddles, that is, the density of heddles increases, abrasion between warp yarn and the heddles causes chafed and broken warp yarn and poor warp yarn arrangements.
  • FIG. 6 shows conventional methods in which one heddle having one eye is mounted on one harness frame. As seen in FIG. 6, in obtaining the desired sheds, the raised yarn C-1 of the upper shed comes into contact with a rod 28 of a harness frame 27 moving the lower yarn 8-2 of the lower shed.
  • FIGS. 7 to 9 show two heddles per harness frame.
  • warp yarn, 5-1, 8-2, C-1 and C-2 are drawn through eyes of heddles 29b, 29d, 29a and 290 are laid together in the direction of the cloth fell.
  • the heddles 29a and 29b are mounted on a stepped harness frame 30 such that the eyes thereof agree with the warp lines Cw and Bw.
  • the heddles 29c and 29d are mounted on a stepped harness frame 31 such that the eyes agree with the warp lines, Cw and Bw. Accordingly, two rows of heddles will become a pair, are mounted on a harness frame and move simultaneously. In this way, the number of the harness frames can clearly be reduced to make great the size of a shed without contact of yarn with a harness frame.
  • FIG. 9 shows that the eyes of heddles 29a" to 29d" are positioned in warp lines and the rods of the harness frame correspond to each other. Owing to the corresponding positions of rods of heddle frames 33 and 34, drawing-in and reeding-in of warp yarn are very simple and processing of harness frames is also simple.
  • FIG. shows that each heddle has two eyes.
  • a heddle 35 has two eyes 36 and 37, and a heddle 38 two eyes 39 and 40.
  • Warp yarn, 3-1, 8-2, C-1 and C-2 are drawn through eyes 37, 40, 36 and 39 and sheds 41 and 42 are formed by shedding motions of heddles 35 and 38.
  • the number of harness frames can be reduced and the desired size of a shed can be obtained.
  • the number of heddles per shed can be reduced to half as compared with a time when a heddle has one eye to inhibit excessive abrasion of warp yarn with heddles. In this case, it
