  • Patent number: 8129294
    Abstract: Novel woven materials, producible by a new weaving method, are described that comprise single or doubled warps and wefts in the form of tapes that are preferably partially stabilized type of fibrous tape. These fibres are caused to occur in a non-linear arrangement during the weaving process. The non-linear fibres can be subsequently straightened by pulling the tape longitudinally. The doubled warps and wefts comprise disconnected tapes. Such separateness of constituent tapes of doubled warp and weft tapes enables them to be slid/slipped relative to each other by pulling longitudinally and laterally without causing any alteration in the woven structure. These novel fabrics solve the problem of uneven fibre distribution and orientation arising from crumples/wrinkles due to compression and stretches due to extension, at the inner and outer sides respectively, when tape-woven fabrics are curved into shapes.

  • Patent number: 7992596
    Abstract: A method of weaving including warp and weft being supplied in the form of tapes, and not yarns. The method preferably carried out in vertical format and includes feeding positively flat tensionless warp for shedding and taking-up; selecting, feeding positively and inserting weft tapes of different widths and thickness by gripping in its fore end in flat condition; depositing inserted weft at fabric-fell in a flat condition without beating-up; and taking-up the woven material that includes either the same or different widths of flat wefts. The warps and wefts, preferably of partially stabilized type of fibrous tapes, can be overfed in a tensionless, positive and controlled manner when required to make the fibres of constituent fibrous tapes occur non-linearly in the form of wave/texture during weaving. Extra warps and wefts can be also fed in tandem whereby the warps and wefts become composed of two or more unconnected, mutually slipping, flat tapes in a stacked arrangement.

  • Patent number: 6539983
    Abstract: The present invention concerns weaving. In particular, it is a woven material produced using tape-like warp and tape-like weft through the employment of a rotary type shedding device which also functions as a direct specific-weave patterning device and a pick guiding device. The material according to the invention has a constructional constitution of at least some of the warp and weft that is non-homogenous. The invention also relates to a weaving device for producing woven material with tape-like warp and weft, comprising a rotary device, which is capable of producing more than one fabric simultaneously.

  • Patent number: 6450208
    Abstract: The present invention concerns weaving. In particular, it is a woven material produced using tape-like warp and tape-like weft through the employment of a rotary type shedding means which also functions as a direct specific-weave patterning means and a pick guiding means. The material according to the invention has a constructional constitution of at least some of the warp (23) and weft (25) that is non-homogeneous. The invention also relates to a weaving device for producing woven material with tape-like warp and weft, comprising rotary means (1), which is capable of producing more than one fabric simultaneously.
