By attaching a spring balance to a dancer roller provided in the middle of the running of a long object, the force of the long object pulling the dancer roller can be measured with a spring balance, and the tension of the long object can be measured indirectly. That is, assuming that the tension of the long object is T, the force F applied to the dancer roller has a relationship of F = 2T. The value of F can be measured with a spring balance. Therefore, the tension of a long object can be determined by halving the value measured by the spring balance.

When the tension of the long object 3 in the line changes, the position of the dancer roller 6 changes and the arm 8 attached thereto moves, and a signal for controlling the operation is transmitted to the drive mechanism 2 through a potentiometer or the like. As a result, the rotation of the motor or the like of the drive mechanism 2 becomes faster or slower, so that the speed at which the long object 3 is fed out changes, and the tension changes. Note that a signal from a potentiometer or the like may be transmitted to an electromagnetic derake or the like, and the drive mechanism 2 may be controlled by the electromagnetic brake or the like.
