Abstract: Beam warping machine with a device for the maintenance of required yarn tension in a group of yarns (5) with rolls (7, 8; 34, 35, 36) around which said group of yarns is wound following an S-shaped path in continuous operation, said pair of rolls being driven without slippage in a operative position (51), whereby brakes (30) acting upon the warp beam (3) are activated when the machine is stopped while at the same time one of the rolls (7,35) is swivelled radially out of its operative position (51) and away from the yarn group (5), whereby the swivelling motion ends in a slippage position (37) which can be selectively adjusted as to degree of swivelling by means of an adjustment link (39), whereby the yarns in the area of the rolls (7, 8; 34, 35,36) braked with the displacement assumes a path allowing for slippage of the yarn group (5) against the rolls (7, 8; 35, 36), said path being straighter than the S-shape.

Abstract: A tenter frame clip which is at least partially constituted from a lightweight polymeric composite material. The clips are employed in tenter frames as components of clip-chain assemblies for grippingly engaging and advancing thermoplastic film webs, fabrics or foils through the tenter frame as the web is concurrently transversely stretched, and for the most part, are generally constituted from either cast iron or cast steel, depending upon the type and size of tenter frame may each readily weigh as much as five pounds, and even higher. The clips are usually extremely strong and tough in their construction and are each able to exert a gripping force of up to 1500 to 2500 pounds.

Abstract: A reinforced V-belt and method relating to same in which the V-belt comprises bottom, middle and top portions, the bottom portion consisting of a layer of bias cushion fabric and one or more layers of a seamless "fiber-loaded" non-woven fabric which has been impregnated with first and second solvent solutions and a plurality of chopped or staple length fibers generally oriented in the cross-machine direction relative to the longitudinal axis of the non-woven fabric; the middle portion consists of rubberized cord and a layer of non-woven fabric disposed on top of the rubberized cord; the top portion consists of bias cushion fabric.

Abstract: A method for manufacturing loom beams for woven fabrics comprising the step of preparing a dividable warper beam which has the form of dividing a conventional single large warper beam into a plurality of divisional warper beams each having a uniform or non-uniform width and the step of using properly these beams together with the single large warper beams to utilize the maximum content of creel at a sizing or warping machine so that the generation of residual yarns can be minimized.

Abstract: A layered yarn package is formed of continuous filament yarn wads wherein the yarn alternates between compacted and extended lengths by axially compacting the yarn into a length, segmenting the length into alternating extended and compacted lengths then arranging the compacted lengths in a common axial direction one next to the other to form a layer. The layer may be compressed. One or more layers may form the package.

Abstract: A texturizing jet for synthetic filaments is openable and closable to facilitate lacing up. A lacing up system is operable in conjunction with the opening and closing mechanism so that the lace-up operation is semi-automatic. At least one of the parts of the jet has a flexible mounting to ensure face to face sealing contact of the parts when the jet is closed.

Abstract: Apparatus for gas jet treatment of moving, continuous multifilament synthetic yarn and a method for cleaning gas jet treatment apparatus are disclosed. A pressurized gas source for the apparatus is selectively disconnected and reconnected to a conduit which supplies a gas jet orifice in a yarn treatment zone. A pressurized liquid is supplied to the conduit when the gas source is disconnected. The liquid is directed forcefully from the orifice into the yarn treatment zone to remove deposits which form during treatment of the yarns.

Abstract: An improved moving cavity yarn texturing device is described. One improved feature is a two stage energy tube which provides for more effective filling of the moving cavity by the yarn. The first stage has a cross section with a major axis an a minor axis. The second stage has a cross section with a major axis and a minor axis whose ratio is less than that of the first stage. A second feature is an improved chamber design which employs a channel having a "V" shaped cross section which eliminates snagging of the yarn by the cavity.
