| 摘要 |
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).
