  • Patent number: 5305802
    Abstract: The weaving machine has at least two sectional warp beams (20a, 20b) and at least one whip roll (23) rotatably mounted to the machine. Each sectional warp beam is equipped with an individually drivable warp let-off motion (30, 31, 32). Feeler members (13a, 13b) are mounted symmetrically on a rocker-like bar (10) to measure the warp yarn tension and control devices individually control the speed of rotation of the sectional warp beams. The rotational axis (11) of the bar (10) is parallel to the warp plane and is situated between the sectional warp beams. A sensor (14a) determines the deviation of the bar alignment from a reference position, so that it is possible to effect warp let-off control.
