Abstract
A face-to-face weaving machine comprising upper (5) and lower spacers (6) for extending in the warp direction between two fabrics (12), (13) and a weft insertion device (2), (3), (4) for inserting weft yarns (22) between the spacers (5), (6), said spacers being carried out as a rigid element with a first (5c), (6c) and a second part (5B), (6B), the vertical intermediate distance between the first parts (5c), (6c) of the spacers (6) being shorter than said distance between the second parts (5B), (6B) such that the weft yarns (22) can be inserted between said second parts (5B), (6B).
Claims7
Face-to-face weaving machine provided to form a shed between warp yarns during successive wet t insertion cycles and each time to insert one or more weft yarns into this shed, so that two backing fabrics (12), (13) may be woven simultaneously above one another, comprising upper (5) and lower spacers (6), which are provided in order to extend between the said backing fabrics (12), (13) in the warp direction during weaving and a weft insertion device (2), (3), (4) designed to insert weft yarns (22) between the upper (5) and the lower spacers (6), wherein the spacers (5), (6) are carried out as a rigid element with a first part (5c), (6c) to form loops and with a second part (5B), (6B) linking up with it, in that the vertical intermediate distance between the first parts (5c), (6c) of the upper (5) and the lower spacers (6) is shorter than the vertical intermediate distance between the two second parts (5B), (6B) of the upper (5) and the lower spacers (6) and in that the said weft insertion device (2), (3), (4) is designed to insert weft yarns (22) between the said second parts (5B), (6B) of these rigid elements.
