Abstract: A harnessing device formed by a locking head and an attached webbed strap. The head contains oppositely positioned locking tangs in a guide channel that receives the strap after encirclement of items to be harnessed. The tangs engage abutments of the webbed strap for adjustable retention of the harnessed items. The strap is advantageously molded of a stretch reorientable material. Stretching produces a relatively thin and strengthened web which resists penetration by the locking tangs and reduces the possibility of failure by fracture or reverse rotation. The inclusion of the relatively thin web also promotes homogeniety during molding and avoids imperfections that can cause failure in other types of straps.

Abstract: A method for producing conventionally usable, stable, preshrunk and crimped yarn from greige self-crimping bicomponent or biconstituent yarn. The method employs a knit-de-knit procedure to impart a so-called mechanical crimp in the self-crimping yarn as that yarn is subjected to an initial heat treatment. The knit-de-knit process has been modified in order to knit the knit-de-knit tubular sleeve more loosely and to obtain a crimp rate per thread line inch within a predetermined range. The knit tubular sleeve is collected in the form of a fabric roll, the internal diameter of which is controlled so that during heating the yarn crimp can develop uniformly. The yarn produced thereby can be used to produce "to size" greige fabric or garments which exhibit better snag or pick resistance than such fabrics or garments produced from conventional greige yarn. These fabrics or garments can thereafter be subjected to normal finishing procedures.

Abstract: Spherical friction or sliding bearings are produced by first making a laminate from a layer of a thermosetting resin and a layer of material having a low friction coefficient. The thermosetting resin is used to impregnate a first web or fabric. The low friction coefficient material may be provided in the form of a further webbing or fabric, for instance, made of polytetrafluoroethylene. The thermosetting material may, for example, be a phenolic resin which is at this point of manufacture in its A-state and hence tacky. In order to permit the immediate further processing of the laminate with the thermosetting resin still in its tacky A-state, a dry adhesive film which neutralizes the tackiness, is applied to the laminate in sandwich formation which is then cut into pieces or strips of suitable size. The sandwich strips are then placed into a mold and pre-shaped and precision cut at room temperatures while the resin is still in its A-state.
