TENSION DEVICE AND METHOD FOR IMPRESSING TENSION IN WINDING MACHINE

摘要

PURPOSE: To provide a tension device and a tension impressing method prepared for a winding machine and capable of setting wide tension values by inexpensive constitution. CONSTITUTION: The tension device is constituted of a non-magnetic plate allowed to be rotated by a rotation means by alternately arranging the N and S poles of permanent magnets in the circumferential direction and a conductor plate rotatably arranged with a prescribed interval from the non-magnetic plate and integrated with an arm arranging a wire material guide on its tip part. The non-magnetic plate is rotated by the rotating means to generate a magnetic field in the conductor plate by electromagnetic induction and the conductor plate and the arm are rotated by torque generated between the magnetic field and the permanent magnets to impress tension to a wire material.
