The weaving machine comprises a needle bar (3) and an insertion element (4) with which warp threads (13, 14) are guided and which are two components of a shed forming apparatus for the manufacture of leno cloths (1). The two components are moved vertically in a reciprocal manner. A horizontal displacement movement (40b) transverse to the direction of the warp threads is executed with the insertion element in addition to the vertical movement (40a). The movements of the two components cause a leno binding to arise in interplay with the insertion of a weft thread (12, 12′). The shed forming apparatus can be modified such that, on the one hand, the horizontal displacement movement (40b) of the insertion element is switched off and, on the other hand, for both components a stroke (h) of the vertical movement (30, 40a) is in each case increased and controlled in such a manner that a cloth without leno binding, in particular a simple cloth (1′), can be manufactured.
Weaving machine comprising a needle bar (3) and an insertion element (4) for warp threads (13, 14), which are components of a shed forming apparatus for the manufacture of leno cloths (1), with the two components being vertically movable in a reciprocal manner and with a horizontal displacement movement (40b) transverse to the direction of the warp threads being executable with the insertion element in addition to the vertical movement (40a), so that a leno binding arises in interplay with an insertion of a weft thread (12, 12′)
9 Use of a weaving machine in accordance with any one of the claims 1 to 8 for weaving simple cloths and/or leno cloths (1, 1′), which are provided as carrier material of pile loops in the manufacture of carpets.
Use in accordance with claim 9, characterized in that a plurality of weaving machines are in operation for the simultaneous weaving of simple cloths and/or leno cloths (1, 1′), with individual weaving machines being used phase-wise for weaving simple cloths (1′) and, after an adaptation in each case of the shed forming apparatus, phase-wise for weaving leno cloths (1).
