<p>PROBLEM TO BE SOLVED: To provide a wire saw for maintaining the orthogonal abutting state of a wire to respective rollers as much as possible, and moreover facilitating the winding of the wire even increasing a working pitch. SOLUTION: A wire W is made travelable orthogonally to working rollers between the rollers 3a and 3b, and orthogonally to guide rollers between the rollers 4a and 4b, and the wire W traveling between the rollers 4a and 4b is made tiltedly travelable so as to be slipped by one pitch Pw part of wire guide grooves 5 provided on the rollers 3a and 3b from the wire W traveling between the rollers 3a and 3b.</p> |
