Abstract
A rotatable tool-assembly for processing wooden panels and the like, of the type comprising at least a first and a second disc blades that are adapted to be fitted on a same spindle, one beside and coaxial with the other; said first and said second disc blades being both provided with a central discoidal body and a cutting toothed crown that comprises a plurality of protruding teeth at least one of which has the front edge covered by a cutting insert; the cutting toothed crown of the first disc blade being structured so as to be able to mesh in an angularly rigid manner with the cutting toothed crown of the second disc blade and vice versa.
Claims17
A rotatable tool-assembly for processing wooden panels and the like, the rotatable tool-assembly comprising:
- at least a first and a second disc blades that are adapted to be fitted on a same spindle, one beside and coaxial with the other, and one or more removable spacer elements separate and distinct from said first and second disc blades;
- wherein said first and said second disc blades are both provided with a central discoidal body and a cutting toothed crown that comprises a plurality of protruding teeth that extend cantilevered from a periphery of the central discoidal body and are appropriately distributed along the periphery of said central discoidal body;
- a front edge of at least one of said plurality of protruding teeth being covered by a cutting insert;
- wherein one or more of the cutting inserts of the first disc blade extend cantilevered sideways of the front edge of the tooth, towards the adjacent second disc blade, and one or more of the cutting inserts of the second disc blade extend cantilevered sideways of the front edge of the tooth, towards the adjacent first disc blade;
- wherein at least one protruding tooth of said first disc blade and/or of said second disc blade is provided with a receiving seat which is located spaced behind the front edge of the tooth, and is shaped/dimensioned so as to house/accommodate any one of the cutting inserts of the adjacent disc blade;
- wherein said one or more removable spacer elements comprise at least one first removable spacer element, separate and distinct from said first and second disc blades, which is provided with a central discoidal body and with a cutting toothed crown that comprises a plurality of protruding teeth which extend cantilevered from the periphery of the central discoidal body and are appropriately distributed along the periphery of said central discoidal body;
- the front edge of at least one of said protruding teeth being covered by a cutting insert that extends cantilevered from both sides of the front edge of said protruding tooth, and is adapted to engage any one of the receiving seats present in the cutting toothed crown of said first and/or of said second disc blade;
- wherein the cutting toothed crown of said first disc blade is structured so as to be able to mesh in angularly rigid manner with the cutting toothed crown of said second disc blade and/or with cutting toothed crown of said first removable spacer element and vice versa.
