<p>One roller on the wire warp system, either the woven metal material take-up roller or the wire warp beam, has a rotary field magnet inserted in the drive mechanism. The tension on the warp wires is converted to a torque at the roller, and the magnet increases or decreases the torque according to a set value to maintain the correct and constant tension on the warp wires.</p> |
