Abstract
In a wire saw primarily intended for sawing stone with the aid of light portable equipment, a continuous, easily flexed wire loop or wire on which cutting elements are uniformly spaced includes elastomeric spacing elements between the cutting elements. With the intention of increasing the flexibility of the wire loop and its ability to endure bending as it runs around guide sprocket wheels of small diameter, the diameter of the wire or the wire loop is reduced. A narrow waist bore which centers against the wire enables the cutting elements to be threaded in a centerd way on the wire. The spacing elements are applied thinly on the wire between the cutting elements. The elastomeric material functions to resiliently center the cutting elements by being pressed against the center plane of the cutting elements from both sides into recesses provided in the end-walls of the cutting elements, theses recess being flared at a wide angle of about 90 degrees.
