  • Patent number: 4711191
    Abstract: A plurality of heavy denier thermoplastic monofilaments is gathered together and continuously wrapped with a flexible wrapper yarn. The wrapped bundle is fed into a stuffer crimper to form a multiplicity of texturized bends. The product is a stiff, pliable texturized yarn and the nomofilaments in the wrapped bundle have a multiplicity of heat-set bends repeating lengthwise along the lengths of the monofilaments.

  • Patent number: 4542619
    Abstract: This invention discloses a yarn, and method and apparatus for making it, composed of a core component having yarn strength wrapped clockwise and counter-clockwise by wrapper components, wherein the core has a sinuous configuration and contains a greater length per unit of yarn length than the wrapper components. Optionally, the core component may be a newly texturized multi-filament yarn, wrapped according to this invention before being subjected to significant tension, thereby preserving much of the bulk that would otherwise be lost in winding or other tensioning of the texturized core in unwrapped condition.

  • Patent number: 4250701
    Abstract: Apparatus and method for making loop chenille type yarns and yarns produced thereby are disclosed. An elongated spindle having a tapered needle surface at one end thereof is provided. The spindle has a passage therein in communication with the needle surface for feeding a core thread to the needle surface. Effect thread is overfed to the needle location where a nose piece member cooperating with the needle aids in wrapping the effect thread about the needle to form loops. The binder yarn is fed to the needle and twisted about the core and effect threads. In a preferred embodiment, means are provided for reciprocating the nose piece relative to the needle between effect thread loop forming and effect thread non-loop forming dispositions. In this manner, "thick" and "thin" novelty yarns are provided in which the thick sections of the yarn comprise looped effect threads whereas the loops are not provided in the thin yarn sections.

  • Patent number: 4165638
    Abstract: An entanglement tester, for testing the degree of entanglement of the yarns such as jet-entangled, yarn, is provided. A complex yarn path is provided, having sections arranged at angles to each other, and a measuring device is provided which may be displaced by shortening the yarn path. Means are provided for inserting a pin or needle into and through the yarn, guiding the yarn onto and off of the pin by using pivoting or sliding guides that are worked by yarn tension, and the yarn is displaced in a manner to shorten the yarn path, thus displacing the measuring device until a point of entanglement is reached. The distance between point of insertion and point of entanglement may be read out, and the measuring process repeated many times without painstaking hand guiding operations.

  • Patent number: 4125922
    Abstract: A jet tangler is provided having a sharply angled passageway for the yarn and having a special air passageway arrangement which minimizes or substantially eliminates the aspiration effect encountered in jet tanglers of the prior art, especially at low tension. The tangler operates efficiently at low or high yarn tension, on texturized or as-produced yarn.

  • Patent number: 4103835
    Abstract: Textile strands are transferred from a full package to an empty bobbin spaced endwise therefrom, by delaying traverse of the winding strand and by picking up the strand and forming a resulting transfer tail on the end of the empty bobbin.The pickup step utilizes rotary bristles located at the spaced adjacent ends of spindles for the respective packages.The transfer delay step may utilize a bistable inertial device positioned to intercept the transferring strand, and functioning to release the strand after a momentary delay, after which delay the strand is wound onto the empty bobbin to begin the formation of a package.The inertial device has adjustable ears and includes variable weights serving to vary the timing delay, whereby the length and position of the transfer tail may be controlled and adjusted.

  • Patent number: 3978560
    Abstract: Textile strands are crimped by feeding them into and forwarding them within a laterally confining region that terminates in a laterally surrounding fine screen with a flared outlet end. The resulting strand-crimping apparatus of stuffer-crimper type utilizes flow of injected fluid to forward or assist in forwarding the crimped strand therethrough.
