PURPOSE:To minimize the range of variations in thread tension in a thread tension regulating device which is provided in a spinner to absorb variations in thread tension, by providing such an arrangement that a braking force is applied to a regulating lever having a thread guide section by means of a braking spring. CONSTITUTION:A self-weighting type thread tension regulating device 10 is disposed between a wind-up drum and a pay-off drum in, for example, an open-end fine spinning machine, and is rotatably supported onto a stationary shaft 11, including a regulating lever 12 having a thread guide 12a at its front end. Further there are provided a braking plate 13 and which is made into contact with the rotating surface 12c of this regulating lever 12 and a braking spring 14, for applying a braking force to the rotating surface 12c. Further, the regulating lever 12 has a small-diameter cylinder 12b which is axially projected from the large diameter base end of the lever 12. Further, there is provided a cylinder 16a secured to a spring retainer plate 16 integrally attached with the stationary shaft 11, the cylinder 16a surrounding the braking spring 14 fitted onto the cylinder 12b. |
