Abstract

Process for the production of steel blades for the cutting of blocks of granite and the like into sheets, starting from a strip of steel wound on spools, comprising subdividing the said strip into lengths substantially equal to that of the finished blade, in making a hole at one end of the same and then subjecting the said blades to a high temperature of approximately 900 degree C for times which vary in relation to the thicknesses of the blades, and then making transverse grooves on the surfaces of the blades using a swaging machine, and then allowing the same to cool to 300 degree C. At this temperature the blades are taken up at their ends by pairs of orientatable clamps and placed under tension for straightening and elongation of approximately 1.5% over a few seconds. After further cooling to approximately 50 degree C the blades are cut to length and provided with a second hole.
