Wire saw for cutting up stone blocks into slabs with tension adjustment of individual saw wires

摘要

A machine for cutting slabs from a block of stone-like material includes: a fixed support structure; at least two rollers mounted for rotation about their axes at opposite ends of the frame and having a means for translating them vertically, the axes of the rollers being horizontal; at least two cutting wires passing around the rollers in such a way that they lie in respective parallel planes, substantially orthogonal to the axes of the rollers; and means for adjusting the tension of each wire independently of one another.
