Rewinding machine

Abstract

Abstract PURPOSE:To enable let-off of a wire rod with high tension from a let-off bobbin and taking-up of the wire rod with low tension by providing a helper capstan for pulling the wire rod between the let-off bobbin and dancer roller. CONSTITUTION:The wire rod 5 (e.g.; optical fiber) is let off from a let-off bobbin 1 driven by a motor and is wound on a dancer roller 7; further, the wire rod 5 is taken up on a take-up bobbin 10 driven by the motor and the speeds of the bobbin 1 or bobbin 10 is corrected by the dancer roller 7. The helper capstan 38 is provided between the bobbin 1 and the roller 7 so that the wire rod 5 is pulled by rotating the capstan 38 with adequate torque. Since the separate and independent setting of the let-off tension and take up tension is thereby permitted, the let-off of the wire rod 5 is stable and the taking-up with the low tension is possible.
