  • Method of cutting blocks of hard substances into plates by means of a wire saw, and wire saw for carrying out this method
    Patent number: 6041766
    Abstract: The invention concerns a method of cutting blocks of hard materials into plates by the action of an abrasive, which is added in the loose state, and of a continuous, revolving, fixed carrier. As a result of being guided in peripheral grooves in coaxial rollers of a roller system, the carrier forms a chain through which the material to be cut is pressed. The carrier, which runs in the peripheral grooves in the rollers of a roller system comprising at least one pair of deflection rollers and at least one pair of guide rollers, is pressed into the material to be cut such that it is guided in opposite directions in respectively two adjacent cuts in the block.
