A method and an apparatus serve to process a catch selvage that has been trimmed from a web being woven on a loom, so as to separate weft thread ends and leno threads from the catch selvage to produce a type-pure weft thread waste and a type-pure leno thread waste or reusable leno threads. The term "type-pure" refers to a waste material containing a single uncontaminated type or color of thread material, e.g. wool vs. synthetic or blue vs. red. After the catch selvage (1) has been trimmed from the edge (11) of the woven web (2), the leno threads (4, 4') are untwisted from each other by being rotated by an untwisting apparatus (5) in a direction opposite the binding twist applied by the leno device (18). Thereby, the full leno binding (1A) is completely unbound and opened, so as to release the weft thread ends (3A), which are then sucked into a proper one of weft waste collection containers (6B) by a suction pipe (6A), so that only a single type-pure and/or color of weft thread end is collected in each container (6B). The unbound leno threads (4) are collected as a type-pure waste or are rewound on spools to be reused. Alternatively, by using endless closed-loop leno threads (4'), the leno threads (4') are continuously recirculated back to the leno device (18), without intermediately being wound onto spools.

Belts and methods of their manufacturing are provided. In one aspect, belts are manufactured by the steps of weaving the belt from a plurality of warp yarns and at least one weft yarn, the belt having a central region and two opposed edges. The warp yarns in the central region have a predetermined shrinkage characteristic. The belts also have at least one edge region between the central region and an edge of the belt has a predetermined number of warp yarns, each having a lesser shrinkage characteristic than the warp yarns of the central region. The method further includes the steps of passing the weft yarn across the warp yarns to effect a weaving in the central region of the belt. Further in the edge region, looping the weft yarn, on each pass, around a selected warp yarn, so that on a plurality of successive passes the weft yarn is looped around each of the warp yarns in the edge region. Subsequently, the yarns in the belt are shrunk.

In 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, the warp yarn is obtained by performing a twisting process of a high degree of twist on a polyester multifilament yarn made of fine single-yarn fibers so as to be highly bound. The polyester multifilament yarn of fine single-fibers is woven at the maximum stretch ratio in a yarn making process to obtain 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.

The invention discloses a fabric for a safety air bag and a production method of the fabric.

The present invention relates to an integrally woven fabric strap having a soft edge on one or both longitudinal sides. The soft edge of the strap comprises spandex covered warp yarns which are thinner than the counterpart warps in the main body of the strap and also has a less dense weaving pattern for reducing weft exposure on the edge warp. Both these technical features contribute to the effect of softness and smoothness of the side edges. With the soft edge, the strap of this invention can find various applications in the underwear industry, as it causes no discomfort despite it is in close contact with the skin and has frequent movement causing frictions thereon during the course of daily wearing.

The warp yarns, the weft yarns and the pile yarns are woven together in a terry weave.

The invention relates to a method, fabrics and machines for producing seamless bags and similar items. The method is characterised in that a weaving loom is used to weave two independent stacked fabrics which are joined transversely at pre-determined distances by interlinking warp threads using weft threads. Simultaneously, independent bands with corresponding selvages along the longitudinal edges thereof are formed in the warp direction in the weaving loom and, subsequently, said bands are fully or partially punched in order to form the bag or similar item. According to the invention, the area between the transverse and longitudinal selvages of one the fabrics to be used includes connecting zones with floating warp threads and connecting zones with floating weft threads. The machine includes means for pulling, tightening and aligning the fabric and means for cutting same in a curved or angular transverse manner.

The brake components of a clutch brake combination in an automatic high speed loom are periodically cleaned to avoid delays in the brake action that occur following a prolonged loom operation without a stopping. The stopping signal is either derived from randomly occurring events or criteria such as a weft breakage or similar criteria on the one hand, or when a criterium stored in the memory or program of the loom control occurs. The respective control signal is generated in response to whichever criterium occurs first.
