Abstract
1399203 Tension control in false twisters ODA GOSEN KOGYO KK 5 Sept 1973 [29 Sept 1972] 41814/73 Heading DID A friction belt false twisting apparatus has its belts arranged in two interlocking sets with entry and exit yarn guides 43, 44, a tension sensor being provided which controls the position of the yarn guides and the degree of interlocking of the friction belts being adjustable e.g. by means of a screw 41. As shown the tension sensor comprises a strain gauge 49 carrying a yarn guide 48. The strain gauge signal is compared to a reference signal and a motor 55 is operated to reduce the signal difference by movement of entry and exit guides 43, 44. This varies the angle of contact of the yarns with the friction belts and hence varies the drag on the yarns. Variation of the interlocking of the belts is used when movement of the yarn guides reaches its limit. Threading up is facilitated by pivoting one set of belts about a pulley shaft 9, Fig. 2.
