Abstract
A loom, especially an air jet loom for producing a leno cloth with integrated patterning includes a weaving reed and first and second shed forming devices. The first shed forming device includes a pivotable reed as a first guide arrangement for guiding and shedding leno warp threads, and an upright reed as a second guide arrangement for guiding and shedding ground warp threads, to form leno bindings. The second shed forming device includes a third guide arrangement for guiding and shedding patterning warp threads, to form pattern bindings. The third guide arrangement is arranged between the first shed forming device and the weaving reed.
Claims20
Loom for the production of a leno cloth with integral patterning, comprising
- a) at least one means for presenting or holding leno threads (2) and ground threads (3) as a first type of warp threads and for presenting or holding patterning threads (4) as at least a second type of warp threads,
- b) suitable means for the deflection of the totality of the warp threads in the direction toward first and second shed forming devices (6,7), whereby
- b1) the first shed forming device (6) effectuates the formation of leno bindings, and
- b2) the second shed forming device (7) effectuates the formation of a binding different from the leno bindings,
- c) means for the insertion of a weft thread (8) into the shed (9), and
- d) a sley (10) with a weaving reed (11) as means for the beating-up of the weft thread against the interlacing point (12) of the cloth (13) to be produced,
- characterized in that the first shed forming device (6) comprises a first leno shed forming guide means (6a) which is operatively connected with drive transmission means (6c), and which drive transmission means (6c) is operatively connected with a drive means (14) of the sley (10),
- characterized in that the first shed forming device further comprises a second leno shed forming guide means (6b) which is operatively connected with at least one further drive transmission means (6d),
- characterized in that the second shed forming device (7) comprises further shed forming means, which are operatively connected with a suitable drive, and
- characterized in that the further shed forming means of the second shed forming device (7) are arranged between the second leno shed forming guide means (6b) of the first shed forming device (6) and the weaving reed (11).
A loom for producing a leno weave cloth having integrated patterning, from ground warp threads, leno warp threads, patterning warp threads, and weft threads, wherein said loom comprises:
- a leno shedding arrangement (6) that is adapted to form leno bindings of the ground warp threads (3) and the leno warp threads (2), and that comprises a first shedding guide arrangement (6a) adapted to receive, guide and move the leno warp threads, a second shedding guide arrangement (6b) adapted to receive, guide and move the ground warp threads, a first drive arrangement (6c) operatively connected to said first shedding guide arrangement, and a second drive arrangement (6d) operatively connected to said second shedding guide arrangement;
- a pattern shedding arrangement (7) that is adapted to form pattern bindings, which are different from the leno bindings, of the patterning warp threads (4) relative to the ground warp threads and the leno warp threads, and that comprises a third shedding guide arrangement (7b) adapted to receive, guide and move the patterning warp threads, and a third drive arrangement (7a) operatively connected to said third shedding guide arrangement;
- a weft insertion device arranged and adapted to insert the weft threads (8) successively into open warp sheds formed of the warp threads by said leno shedding arrangement and said pattern shedding arrangement;
- and
- a sley (10) carrying a weaving reed (11) arranged and adapted to beat the weft threads successively against a beat-up interlacing point of the cloth being produced, and a sley drive arrangement (14) operatively connected to said sley;
- wherein:
- said first and second shedding guide arrangements driven respectively by said first and second drive arrangements are movable relative to one another in an up-down direction and in a lateral side-to-side direction so as to form the leno bindings;
- and
- said pattern shedding arrangement (7) is arranged between said leno shedding arrangement (6) and said weaving reed (11).
