20080257443 | Method and Apparatus for Weaving Tape-Like Warp and Weft and Material Thereof - A novel method of weaving is described wherein warp and weft are supplied in the form of tapes, and not yarns. In at least one embodiment, the method, which is preferably carried out in vertical format, essentially 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 comprises either 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. These doubled warps and wefts function effectively as a unit warp and weft during weaving and in the fabric. In at least one embodiment, the method also makes possible to produce other materials such as those with slant weft tapes in relation to warp, having a shape within the body of the fabric and warp and weft tapes of shaped edges. A variety of fibrous and non-fibrous materials are equally well processed. | 10-23-2008 |
20090007981 | Woven Material Comprising Tape-Like Warp and Weft, and an Apparatus and Method for Weaving Thereof - 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. Further, by using doubled warps and wefts fabrics with relatively flat/planar sections and thicker/raised wide rib sections can be also created that resemble a bit like a profiled material in its cross-section. Other fabrics like those comprising slant/oblique weft tapes, shaped warp and weft tapes, formed shape within its body are also producible. | 01-08-2009 |

20140083553 | METHOD AND MEANS FOR PRODUCING TEXTILE MATERIALS COMPRISING TAPE IN TWO OBLIQUE ORIENTATIONS - A novel method and means for directly producing a variety of textile materials comprising tapes oriented in two opposite oblique orientations relative to the textile's length and width directions, called Oblique Fibre Textile (OFT), are disclosed. The described method and means for producing OFT provide secondary structural integrity/stability to OFTs, in addition to primary structural integrity/stability. The process is especially advantageous for producing OFTs comprising tapes, including Spread Fibre and Highly Drawn Polymeric types. Such OFTs are needed in a number of applications such as ballistic mitigation, composite materials, safety products etc. for their improved performance, functions and aesthetics. Several different types of OFTs are producible by the novel OFT forming process which is technically unlike weaving and braiding processes. | 03-27-2014 |
