Abstract
The present invention relates to a cutting block for a sawing machine for sawing stone blocks into slabs which has a pair of opposed yokes for tensioning a plurality of blades by means of tie-bars with spurs, wherein the tie-bars which hold the blades have a single spur between two blades placed side by side.
Claims17
A cutting block for a sawing machine for sawing stone blocks into slabs, comprising a pair of opposed yokes for tensioning a plurality of blades by means of tie-bars with spurs, said tie-bars which hold said blades each have a single spur between two substantially parallel blades;
- each said spur constitutes a spacing straightedge for said two blades;
- and
- wherein each said spur has lateral surfaces for support of said two blades placed side by side, arranged at a predetermined distance.
A cutting block for a sawing machine for sawing stone blocks into slabs, comprising a pair of opposed yokes for tensioning a plurality of blades by means of tie-bars with spurs, said tie-bars which hold said blades each have a single spur between two substantially parallel blades;
- and
- each of said tie-bars includes a respective flank having two L-shaped channels at one end of each said respective flank for coupling to each of said blades and constituting incomplete seats for said blades.
A cutting block for a sawing machine for sawing stone blocks into slabs, comprising a pair of opposed yokes for tensioning a plurality of blades by means of tie-bars with spurs, wherein said tie-bars which hold said blades each have a single spur between two substantially parallel blades;
- each said spur constitutes a spacing straightedge for said two blades;
- said tie-bars co-operate with plate-like reinforcing members, and each said plate-like reinforcing member is provided with a spur,
- said reinforcing members are coupled by pressure to the flanks,
- said reinforcing members are connected to said flanks by threaded means screwed into threaded holes provided in the tie-bars, and
- said threaded means each have a head adapted to be countersunk in seats provided in said reinforcing members.
A cutting block for a sawing machine for sawing stone blocks into slabs, comprising a pair of opposed yokes for tensioning a plurality of blades by means of tie-bars with spurs, wherein said tie-bars which hold said blades each have a single spur between two substantially parallel blades, wherein said tie-bars are arranged with flanks in mutual contact.
A cutting block for a sawing machine for sawing stone blocks, the cutting block comprising:
- at least two opposing tie-bars operative to hold a plurality of blades extending between the tie-bars;
- each tie-bar having an end, a respective spur coupled to the end of each tie bar, and each spur is positioned between two respective blades, each spur providing a straightedge space between the two blades, and each spur including lateral surfaces to support the blades;
- and
- a pair of opposed yokes coupled to the at least two opposing tie-bars and operative to adjust the tension of the plurality of substantially parallel blades.
