PROBLEM TO BE SOLVED: To adjust the position of the groove between respective guide rollers automatically. SOLUTION: A guide roller 16 is movably supported along the axial direction of the roller, and the movement of the roller in the axial direction is regulated with rubber. In this case, when the mutual groove positions of the neighboring guide rollers are deviated, the respective guide roller receives the force of the axial-direction component of the tension of a wire 14 for guiding in the axial direction. When the force of the axial-direction component of the tension of the wire 14 is received, each guide roller is moved along the axial line so as to eliminate the deviation. Thus, the deviation of the groove positions of the respective guide rollers is eliminated. |
