RING PLANING SAW FOR FINISHING RIP-AND-CROSS CUTTING OF WOOD Russian patent published in 2000 - IPC

FIELD: woodworking and furniture industry. SUBSTANCE: all right- and left-hand planing and cutting teeth positioned sequentially on saw disc have sharpened front, back-off and rear edges which allows every tooth to participate actively in woodworking by two operating edges (blades) irrespective of arrangement of planing and cutting teeth (by front edges and/or rear edges) in direction of saw disc rotation. If saw gets blunt its intersharpening period may be increased by turning saw disc to other side, that is by changing the working rotation of saw. Saw may also be used for finishing planing of wood surfaces. Invention makes it possible to extend functional capabilities of saw and to improve woodworking quality. EFFECT: simplified construction. 3 dwg
