Abstract: A woven ribbon, preferably a vehicle safety belt strap, is produced on a needle weaving loom. The weft yarns alternately picked from right and left are crocheted with the respective preceding weft already picked.

Abstract: An automatic heddling method and a related automatic heddling apparatus 100, by which a plurality of heddles 2 removed from a plurality of heddle frames 1 are integrally collected in such a manner that flat faces 11 of the heddles 2 may face opposite to each other, then a dummy yarn 4 is inserted simultaneously through heddle eyes provided respectively in the plurality of heddles 2 while they are in a collected state, and then the heddles 2 are individually carried with keeping the contact to the dummy yarn 4, from a collecting position 5 of the heddles 2 to a predetermined individual heddle frame designating means 6.

Abstract: A thin and light webbing having a high strength per warp yarn unit, maintaining abrasion resistance, and using, as a warp yarn, a very strong polyester multifilament yarn for a seat belt made by fine single-yarn fibers. A yarn obtained by performing a twisting process of a high degree of twist is used as a warp yarn. The polyester multifilament yarn of fine single-fibers is essential to be woven at the maximum stretch ratio in a yarn making process to obtain a very-strong polyester fiber for a seat belt. A multifilament yarn and/or a monofilament yarn of polyester is/are used as weft yarns. By making the weft yarns and warp yarns cross each other so as to be woven in a belt like configuration, a webbing having a very high strength per unit of warp yarns, using low-cost base yarns, and maintaining abrasion resistance is obtained.

Abstract: Disclosed is a thin and light webbing having a high strength per warp yarn unit, maintaining abrasion resistance, and using, as a warp yarn, a very strong polyester multifilament yarn for a seat belt made by fine single-yarn fibers. A yarn obtained by performing a twisting process of a high degree of twist which is not common for a conventional seat belt by a novel twisting method of a very low cost on a polyester multifilament yarn made of fine single-yarn fibers so as to be highly bound unlike the conventional method is used as a warp yarn. The polyester multifilament yarn of fine single-fibers is essential to be woven at the maximum stretch ratio in a yarn making process to obtain a novel very-strong polyester fiber for a seat belt. A multifilament yarn and/or a monofilament yarn of polyester is/are used as weft yarns.

Abstract: An apparatus for producing high quality products of cloth strip by the improvement of working efficiency and the equalization of treatment conditions, wherein the cloth strip (2) is subjected to a predetermined treatment while passing through one treatment zone (3) along a spiral path. A plurality of metallic surface rollers (5-2 to 5-4), surfaces of which are formed with metal, are used as at least part of conveying rollers consisting of metallic rollers (5-2 to 5-4) for guiding the cloth strip (2), provided in at least one of entrance and exit parts for the introduction/withdrawal of cloth strip (2) to the treatment zone (3). The metallic surface rollers (5-2 through 5-4) are arranged in a non-contacted state with each other and positively driven to rotate via a suitable drive mechanism (6).

Abstract: A creel 1 with twisting devices is capable of directly supplying twisted yarns from bobbins carrying non-twisted yarns to a loom or a warper, and of producing not only normal fabric but also a fabric having a low weft density woven at a higher rate or a fabric using hard-twist yarns as warps. A plurality of rotatable spindles 8, each carrying a bobbin 3 on which a non-twisted yarn 2 is wound, are arranged on a frame 18. The yarns 2 withdrawn from the bobbins 3 on the spindles 8 are twisted and arranged to form a yarn sheet 19. The spindles 8 are rotatably secured via bearings to the frame 18 of the creel 1 at the center of a rotary shaft section 8' which is arranged in a horizontal direction. On both ends of the rotary shaft section 8', a section for supporting the bobbin 3 carrying the non-twisted yarn 2 is formed, on which a two-for-one twisting device 21 is provided.

Abstract: A creel for directly supplying twisted yarns to a machine (13) such as a loom or warper from a plurality of yarn bobbins (3) arranged on a creel (1) for holding non-twisted yarn (2). Two banks of bobbins (3), optionally contrarotate at a predetermined speed to respectively provide "S-twisted" and "Z-twisted" yarn streams (4) having a desired twist number. The bobbins (3) are disposed on a plurality of spindles (5) that are driven by suitable drives (6). A bobbin attachment (7) is mounted at a free end of each bobbin (3) and fixedly supported on the spindle (5). A yarn storage (8) is provided on the attachment (7) and includes a yarn adjustment ring (9) for providing yarn delivery in a stable manner under appropriate tension. Once the yarn has passed the yarn storage (8) and yarn adjustment ring (9), a desired twist is imparted to the yarn (2), and twisted yarn (4) is delivered to the machine (13).

Abstract: A creel which can deliver untwisted yarns from bobbins in a weaving machine while at a same time twisting them or else twisting some of such untwisted yarns in the S twist and the remaining untwisted yarns in the Z twist with relative low investment for equipments. The creel employs a mechanism similar to a ring twisting mechanism and includes a required number of spindles for rotating bobbins supported thereon, a ring secured in a concentrical relationship to each of the spindles, a traveler mounted for movement on each of the rings, and a driving device for driving the spindles to rotate in a clockwise or counterclockwise direction such that when the untwisted yarns are unwound from the bobbins via the travelers, a twist in the S or Z direction may be applied to the untwisted yarns at a same time.
