  • Patent number: 10982357
    Abstract: Various examples are provided for non-stop tying-in process for weaving of textiles. In one example, a method for non-stop tying-in of loom warps during operation of a loom includes providing free ends of a replacement warp sheet and a warp sheet tail to the tying-in machine during the operation of the loom, where the warp sheet tail is provided through a warp accumulator; accumulating the warp sheet tail in the warp accumulator during tying-in of the free ends; supplying at least a portion of the warp sheet tail accumulated by the warp accumulator to the loom after being released from a warp beam; removing the tied-in warp sheet tail and replacement warp sheet from the warp accumulator; and supplying the replacement warp sheet to the loom during its operation.

  • Publication number: 20050034376
    Abstract: A filler or pack material composed of homocomponent or multi-component fibers comprising various polymers with varying melting behavior. Most suitably, the filler fabric's volume fraction is between 10% and 70%. The filler can be cut, shaped, molded and fitted into the gutter. Additionally, single component or multi-component fibers can also be used together with other solids such as foam to form filler.

  • Patent number: 5094067
    Abstract: This is disclosed a yarn re-structuring method and apparatus for modifying the structure of a spun yarn in order to improve its properties, in which the yarn is subjected to the action of successive false twisters in order to impart a permanent modification to the structure of the yarn, in which there is a tandem arrangement of first and second oppositely acting false twisters, with the first false twister acting to at least partially unwind the origianl twist in the yarn and the second false twister acting at least partly to restore or to increase the original twist in the yarn. This action on the spun yarn improves the properties of softness and bulkiness, while retaining acceptable performance of the yarn in other characteristics.

  • Patent number: 4258454
    Abstract: Apparatus for feeding fibres, and particularly worsted fibres to a carding machine that may be a conventional worsted card or conventional cotton card. The apparatus comprises a stationary feed plate (1), a rotatable feed roller (2) and a rotatable takerin (3) for carrying fibres from the feed roller and transferring them to the surface of a carding cylinder. The surface of the takerin is furnished with pins at a pin density of not more than 36 pins per square inch (5.58 pins per square centimeter) and the distance (B) between the feed plate and the envelope of the tips of the pins on the takerin is from 0.3 to 0.75 inch (0.76 to 19.5 mm). Using this low pin density and wide spacing between the feed plate and the envelope of the pin tips effects excellent cleaning of worsted and other long staple fibre before it passes to the carding cylinder.
