  • Patent number: 3953989
    Abstract: In a fabric constituted lengthwise of stitched warp threads and, transverse thereto, an array of weft threads substantially parallel to one another, the array of weft threads is in the form of repeating sections, each section comprises a plurality of discrete portions of weft threads and each discrete portion extends in a continuous line at least twice from one lateral border of the fabric to the other lateral border of the fabric and forms a U at at least one of the borders of the fabric. This fabric is made by a method and with an apparatus in which the weft threads are transferred to two feeding means which transport the weft threads to a zone in which warp threads are stitched into the array of weft threads, the transferring being effected by a weft layer which moves between the feeding means transversely to the direction of motion of the feeding means and, at selected intervals, parallel to the direction of motion of the feeding means.
