<p>Two grooved rollers (11, 12) among three grooved rollers (11-13), around which a saw wire (14) is passed, are arranged in upper and lower positions, and the saw wire (14) runs vertically between the grooved rollers (11, 12). A work (9) is moved horizontally to be pushed against the vertically running saw wire (14). Preferably, the grooved roller (13) is positioned at substantially the same level as the lower grooved roller (12) is.</p> |
