Abstract (en)
[origin: EP3753887A1] In a yarn tension adjusting device (2) that adjusts tension exerted on a yarn (Y) held between opposing surfaces (211 and 221) of first and second disks (21 and 22) opposing each other, the first disk (21) is movable toward or away from the second disk (22) on the same shaft (23). A permanent magnet (24) is disposed on the first disk (21), whereas an electromagnet (25) coupled to a power source to be capable of changing a magnetic pole and electric current is disposed on the second disk (22). A coil spring (27) that constantly urges the opposing surface (211) of the first disk (21) toward the opposing surface (221) of the second disk (22) is contracted between a screw member (28) screwed at a first end of the shaft (23) and a surface of the first disk (21) opposite to the opposing surface (211).
