  • Patent number: 4078586
    Abstract: A method and apparatus for producing a selvage on a fabric woven on a loom in which filling threads are drawn from a stationary supply outside the shed formed by the warp yarns. The method and apparatus includes inserting a first filling through the shed. The ends of the first filling are clamped by a first pair of clamps positioned on opposite sides of the shed which hold the filling in an extended position. The filling thread is beat-up into the fell of the fabric and simultaneously the ends thereof are displaced behind the fell of the fabric for engagement by a second pair of clamps. The filling is then severed outside of the second pair of clamps so that the second pair of clamps continues to hold the ends of the filling in an extended position behind the fell of the fabric. The shed is then changed and the above steps are repeated until a predetermined number of fillings are held by the second pair of clamps.
