  • Patent number: 7114424
    Abstract: A sawing device includes a holding device (22) arranged so as to hold in the course of wire sawing the different sawed slices (23) substantially parallel and such that the width of the sawing gaps (24) is held constant. The device includes, for this purpose, holding members (25), for example in the form of a bar (30) whose resilient coating (31) is applied by springs (35) against a lower portion (26) of the slices (23) . There are thus obtained slices without undulations, striations, breakages and irregularities; moreover, the invention permits easy repair of the layer of wires after breakage of the wire.

  • Patent number: 6981495
    Abstract: In the sawing process and device according to the invention, the pieces to be sawed are mounted on at least one support table and caused to bear against a layer of wires. Inclination structure in the form of wedges or pieces for angular adjustment by pivoting and blocking, are provided to mount the pieces obliquely with angles of inclination between one of their prismatic surfaces and a horizontal working plane. There is thus obtained a precise beginning of sawing with sawed slices of equal thickness and a careful end of cutting without chipping.
