業能率を低下させる原因となっている。The wire saw-type cutting device requires a proper tension on the wire saw.
A wire saw whose length is adjusted according to the size of the object to be cut is used. That is, the object to be cut is small and the wire saw
If the wire saw sags, the wire saw is cut to shorten it. Conversely, if the wire saw intended to be used for the object to be cut is too short, a spare wire saw of an appropriate length is added and used. However, this length adjustment is a troublesome and complicated work, and it is difficult to do this at a construction site or the like, which causes a reduction in work efficiency.

いる。Further, since the wire saw is expensive, the scrap produced by the length adjustment is stored as a spare part and used as a supplement to another wire saw having a short length.
Since the wire saw wears down due to use and the diameter of the cutting edge becomes smaller, adding a spare scrap with less wear to this causes excessive force to be applied to this part, causing abnormal wear or cutting problems. May occur. Therefore, an object of the present invention is to make it possible to easily adjust the length of the wire saw without performing cutting or adding.
