Abstract: The invention relates to a device for adjusting the tension of pile warp yarns in a face-to-face weaving machine, the device comprising a first (14) and a second yarn guiding element (11), the second yarn guiding element (11) adjusting the tension in the pile warp yarns (100) by deflection, and where a pneumatic system (16) is provided, where the pressure in the pneumatic system (16) determines the deflection of the second yarn guiding element (11) and where the pneumatic system (16) is provided to maintain the pressure at a practically constant value, adjustable via the control system. The device is further provided so that the tension in the pile warp yarns (100) is adjustable by adjusting a certain pressure in the pneumatic system (16).

Abstract: In face-to-face weaving pile fabrics with high pile density, groups of three weft yarns (1-3), (4-6) are inwoven in respective openings between binding warp yarns (7), (8), (9) (10) crossing each other, and non-pile-forming pile warp yarns are inwoven, while pile warp yarns are alternately interlaced in the top and the bottom backing fabric over a weft yarn according to a two-shot weave. In series of four successive weft insertion cycles in each case three weft yarns (1), (2), (3) are inserted for the top backing fabric (30) and three weft yarns (4), (5), (6) for the bottom backing fabric (31). A weaving machine inserts two weft yarns one above the other per weft insertion cycle and by weft disengagement or weft cancellation in the course of two cycles per series inserts only one weft yarn. Two pile-forming pile warp yarns after a pile change are interlaced over a weft yarn.
