Abstract
A system for bringing ground warp threads under tension on a beam stand comprises first and second rollers on which the ground warp threads run. The first roller is mounted on a support which is movable in relation to the second roller. A mechanism for exerting force on the support is provided whereby the ground warp threads on the beam stand are brought under tension. The mechanism includes a hydraulic element that is connected to a hydraulic pressure vessel by a pipe provided with an apparatus for controlling or regulating the hydraulic fluid.
Claims4
A system for bringing ground warp threads under tension on a beam stand comprising:
- a) a first roller on which the ground warp threads run;
- b) a second roller on which the ground warp threads run;
- c) a support on which said first roller is mounted and which is movable in relation to the second roller;
- and
- d) a hydraulic element exerting force on said support whereby the ground warp threads on the beam stand are brought under tension, said hydraulic element being connected to a hydraulic pressure vessel by means of a pipe, said pipe including an adjustable and controllable hydraulic fluid valve allowing regulation and control of hydraulic damping in said pipe.
