Abstract
A single-web loom for loop velvet fabric wherein weft yarns are inserted in a shed (F1) formed by warp yarns and wherein individually controlled electric actuators are used to move at least one warp yarn guide heddle into one of at least four positions (N1, N2, N3, N4) defining at least three warp yarn sheds (F1, F2, F3), and wherein warp yarn guide rods are simultaneously inserted into each of the sheds (F2, F3) other than the shed (F1) into which the weft yarns are inserted for forming loops or pile.
Claims12
A single-web loom for loop velvet fabric, the loom comprising:
- a plurality of electric actuators, each actuator being connected to move at least one heddle for guiding a warp yarn into one of at least four positions defining at least three warp yarn sheds;
- a plurality of individual controls for controlling operation of the electric actuators;
- means for inserting weft yarns in a first shed formed by warp yarns;
- and
- means for simultaneously inserting into each of the sheds other than the first shed formed by warp yarns a respective warp yarn guide rod for forming loops or pile.
A method of weaving single-web loop velvet in which weft yarns are inserted in a first shed formed by warp yarns, wherein the method comprises the steps consisting in:
- a) controlling the positions of the warp yarns by means of individually-controlled electric actuators, bringing a plurality of warp-yarn guide heddles into at least four height positions defining at least three sheds;
- and
- b) inserting simultaneously, into each of the sheds other than the first shed, a respective guide rod for guiding warp yarns for forming loops or pile.
