ABSTRACT:
A constant tension regulator for controlling the tension of positively unwound flexible material, particularly warp threads in a weaving machine. Means are operatively mounted on the frame of the regulator for sensing changes in tension in the unwinding flexible material. These sensing means output a control movement in accordance with sensed tension in the unwinding flexible material which is translated to a mechanical integrating unit and a proportional adjusting unit, arranged in parallel, which jointly transmit a control variable adjustment to the driving means of the warp beam thereby adjusting its rotary speed in accordance with the sensed tension.
