Definitions

  • the present invention seeks to provide an endless rotating blade for a band saw for cutting various materials, such as for example marble, concrete, steel and similar metals, originality residing mainly in the 5 the fact that said blade is provided with small diamond blocks which are welded to it, for example by brazing or other system.
  • endless rotating band saws for working with hard materials would however be desirable both in terms of the continuity of the cutting work which these saws make it possible, as well as with regard to the forward speed.
  • circular saws it being noted that they allow a wider field of use because they can be used for an unlimited depth of cut, which obviously cannot be achieved using circular saws.
  • these blocks 2 slightly extend in width the thickness of the blade 1, so that on the sides of the furrow or trace of cutting it is these blocks which act on the material to be cut by deepening the work.
  • the endless rotating blade 1 is mounted, as usual, on a band saw while being supported by two pulleys 3 and 4 (fig. 3) provided with means suitable for ensuring the perfectly centered rotation of the blade on each of said pulleys, without risk of abnormal position.
