  • Spindle unit
    Patent number: 11760600
    Abstract: A spindle unit includes a swing mechanism fixed to a fixed frame, a support member swingably supported by the swing mechanism, a spindle main body and an electromagnetic brake supported by the support member. The spindle main body rotates integrally with a bobbin around which a yarn is wound. The electromagnetic brake applies a resistance to the rotating spindle main body. The swing mechanism includes a fixed attachment member fixed to the fixed frame, a swing shaft supported by the fixed attachment member, a spring, and a sensor. The spring applies a spring force to the support member in a direction opposite to a direction in which the support member swings by the tension of the yarn. The sensor detects the tilt amount of the support member when the support member swings.

  • Spindle unit
    Patent number: 11427432
    Abstract: A spindle unit includes a support shaft, an electromagnetic air-gap brake, a spindle member, and a coupler. The support shaft is attached to the stationary frame of a creel. The brake is connected to the front end of the support shaft. The spindle member is rotatably supported by the support shaft in a state in which the support shaft and the brake are inserted in the spindle member. The coupler couples the spindle member and the brake shaft.
