摘要： A loom allows a implementing a method for weaving a fabric (F), with warp yarns (412, 414, 422, 424) and inwoven weft yarns (61, 62, W1-W5). The loom (2) comprises a warp delivery unit (8); heddles (14) for moving warp yarns in order to form a shed; a mechanism (12) for moving (F1) each heddle vertically along a vertical path; weft insertion means (21, 22) for inserting each weft yarn in a shed (S1, S2) and for releasing the weft yarn at a given location along a weft axis (Y1, Y2); and weft delivery means (28) for delivering weft yarns (61, 62, W1-W5) to the weft insertion means, this method comprising, for at least two consecutive picks, at least the following steps consisting in a) opening the shed (S1, S2); b) picking, by the weft insertion means (21, 22), of a first end (612, 622) of a weft yarn (61, 62, W1-W5) presented by the weft delivery means (28); c) drawing (A3) the weft yarn into the shed, along the weft axis (Y1, Y2); d) releasing the weft yarn at the predetermined position along the weft axis; e) withdrawing the insertion means from the shed; and f) beating-up the weft yarn wherein, during step c), the shed is closed around the inserted weft yarn (61, 62), by moving warp yarns (412, 414, 422, 424) of a predetermined group (G4, G4′) of warp yarns to a semi-closed position. The loom also comprises programmable clamping means (24) for picking up the first end (612,622) of the weft yarn (61, 62, W1-W5) at step b), for drawing the weft yarn into the shed at step c) and for releasing the weft yarn at step d), at any predetermined position along the weft axis (Y1, Y2) and a programmable mechanism (12) including actuators for semi-closing the shed around the inserted weft yarn during step c), at any predetermined position along the weft axis.

摘要： A method for weaving a fabric (F), with warp yarns (412, 414, 422, 424) and inwoven weft yarns (61, 62, W1-W5), on a loom (2) which comprises a warp delivery unit (8); heddles (14) for moving warp yarns in order to form a shed; a mechanism (12) for moving (F1) each heddle vertically along a vertical path; weft insertion means (21, 22) for inserting each weft yarn in a shed (S1, S2) and for releasing the weft yarn at a given location along a weft axis (Y1, Y2); and weft delivery means (28) for delivering weft yarns (61, 62, W1-W5) to the weft insertion means, this method comprising, for at least two consecutive picks, at least the following steps consisting in a) opening the shed (S1, S2); b) picking, by the weft insertion means (21, 22), of a first end (612, 622) of a weft yarn (61, 62, W1-W5) presented by the weft delivery means (28); c) drawing (A3) the weft yarn into the shed, along the weft axis (Y1, Y2); d) releasing the weft yarn at the predetermined position along the weft axis; e) withdrawing the insertion means from the shed; and f) beating-up the weft yarn wherein, during step c), the shed is closed around the inserted weft yarn (61, 62), by moving warp yarns (412, 414, 422, 424) of a predetermined group (G4, G4′) of warp yarns to a semi-closed position.
