ABSTRACT:
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 thread is executed with the insertion element in addition to the vertical movement (40a) The movements of the two components cause a leno binding to take place 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.
