Abstract (en)

A tension applying device has a fixed disc 24 and a movable disc 25 provided close to the fixed disc 24, and includes a plurality of tension applying portions 15, 16 that slide a traveling yarn Y1 between the fixed disc 24 and the movable disc 25 to apply tension to the yarn Y1. At least any one of the plurality of tension applying portions 15, 16, for example, the tension applying portion 16, includes a compression coil spring 34 on the movable disc 25 side and is configured such that action of the compression coil spring 34 biases said movable disc 25 toward said fixed disc 24. The tension applying device further includes a switching means 60 for switching the tension applying portion 16 between an operative state in which the tension applying portion 16 applies tension to the yarn Y1 and an inoperative state in which the tension applying portion 16 applies no tension to the yarn Y1 (Fig.2).
