Abstract (en)

[origin: EP0841418A1] The mechanism to control the warp tension, in a loom, comprises at least one shut-off (34) in the linking channel between a hydraulic spring unit (21) at the warp tensioner (4), and the hydraulic fluid container (33). Increasing or decreasing the hydraulic fluid volume alters the stiffness of the hydraulic spring unit to define the swing movement range of the warp tensioner.
