  • Method and apparatus for providing the warp thread end of a fabric ribbon
    Patent number: 6016851
    Abstract: A method and apparatus for providing warp thread ends as auxiliary weft in a seam weaving device is disclosed and where the warp thread ends are connected to an adhesive seam and a weft thread bundle is formed in the warp thread ends. An auxiliary shed is then formed in the weft thread bundle for successively releasing the warp thread ends from the weft thread bundle. After being released from the weft thread bundle, each successive warp thread end is separated from the warp thread ends which are retained by the weft thread bundle and then cut from the adhesive seam. This allows the warp thread end to then be withdrawn from the auxiliary shed to be provided as an auxiliary weft in a seam.
