Abstract: A picking comb, particularly for jet looms. The comb has an array of active, monitoring and passive guide teeth each having a picking portion and a mounting portion and fixed by its mounting portion in spaced side-by-side releation on a carrier means. At least one of said guide teeth has its picking portion separate from its mounting portion. The picking portion is provided with a connecting element fitting into a corresponding bore in the mounting portion. Correct positioning of the two portions is assured by interfitting positioning parts and a clamping element. The detachable connection between the picking portion and the mounting portion of a tooth makes it easier to replace a defective picking portion without the necessity of removing the whole picking channel or a section thereof.

Abstract: The warp beam is constructed with a hollow tube on which flanges can be symmetrically mounted as well as with a tubular extension at one end to permit asymmetric mounting in the bearings of a weaving machine. The warp beam is shaftless and the extension element has a slightly greater diameter than the diameter of the warp beam tube so as to render the warp beam more rigid. The rigidity of the warp beam reduces distortions and vibrations of the warp beam during weaving.

Abstract: A novel low bulk seam is disclosed for use in paper making machine fabrics, such as dryer felts. The seam is particularly adapted for use with multi-filament yarns which comprise multi-ply fabrics. A novel method for producing this seam is disclosed which comprises the insertion and adhesion of a seaming coil, the removal of picks in adjacent fabric areas, the folding and overlapping of such areas, the creation of a warp fringe, and the pulling of portions of that fringe into and through portions of the fabric body fasteners to create a stitchless seam providing substantially uniform thickness and air permeability across the full fabric width. A durable, reliable, non-marking seam is accordingly provided for use with spun, mono-filament and/or multi-filament fabrics.

Abstract: A small weapon, such as a short-bladed defensive knife can be innocently concealed in an article of ordinary apparel, such as a belt, according to the present invention in such a manner as to both be securely retained within the article of apparel and be quickly and simply withdrawn by a simple, single motion when needed in instances of self-defense. The weapon is retained within the article of apparel by frictional engagement between the article and the weapon, which is primarily achieved by different curvatures of the holster, which is combined with the article of apparel, and of the weapon. The frictional engagement between the weapon and the holster can be increased by providing additional end clips, protrusions, or other attachments between the weapon and its holster.

Abstract: The belting has a single layer woven central portion (24) and two tubular edge portions (21, 22) and is made on a needle belt weaving loom provided with a knitting needle (37). The belting serves preferably for safety belts in motor vehicles. One tubular edge portion (22) is closed by a row of stitching (28') whereby the row of stitching does not lie at the outer edge of the tubular edge portion (22) but should disappear into the fabric at the edge of the central portion (24). By means of the invention the rate of production should be increased, which results from manufacture with two simultaneously moving weft thread insertion needles (30, 34) which simultaneously at each pick insert two weft threads (31, 35). To anchor one weft thread at the outer edges of the edge parts a common shed for both weft thread insertion needles is formed at least on the insertion side by the two outer edge warp threads (1a, 2a).
