Abstract

PURPOSE: To improve the quality of a coil by means of enabling the work of providing a less change in a tension while in a winding work, in the tension device used for the winding work of a horizontal coil, a principal part of the TV deflecting yoke, and for other winding machine.
CONSTITUTION: Firstly in a tension generating part 2, with a pulley 4 installed to an output shaft 5 of non-contact electromagnetic brake 3, a torque of the above described brake 3 is given to a wire 7 as a tension in a friction by means of rolling the wire 7 several turns. Subsequently in a looseness absorbing unit 9, the wire 7 is wound between a moving pulley 10 and a fixed pulley 16, to absorb a looseness of the wire 7 produced in the winding. And in a control part 22, with a cam 23 installed to a rotary shaft 21 of a bobbin frame 20, as well as with a cam follower 24, making an amplitude motion along a shape of the cam, mounted to the point end of a lever 25, further with a potentiometer 27 provided in a supporting point 26, a voltage, fed to the above described brake 3, is controlled.
