Abstract: A device for adjusting a sawing device's width, wherein the sawing device comprises at least two circular blades 10, 12, facing each other and adjacently positioned, and a fastener 44 adapted to assemble the blades together. The device for adjusting the sawing device's width comprises a wavy annular spring 14 provided between the blades, a recess 42 provided in each of the blades, wherein the recesses are positioned opposite to one another and wherein said wavy annular spring is received within the recesses, an adjustment member 32 adapted to force the blades together against said wavy annular spring or to part them so as to maintain a predetermined distance between the blades. The distance between the blades is set to present a desired cutting width.

Abstract: An improvement in a slotter comprising a shank (10) having a distal side and a proximal side, the shank is adapted to be rotated about a rotatory axis at least two adjacently positioned cutters (20, 24) provided with blades (22); and a nut (34) adapted to uphold the cutters (20, 24) on said shank (10). The improvement for adjusting the width of the cutters comprising a hollow bolt (26) adapted to be mounted on the shank wherein one of the cutters is a movable cutter (24) that is screwed on said hollow bolt (26), and a cap (28) mounted on the shank receives a portion of said hollow bolt and confines the movement of the bolt. Adjusting the width of the cutters is established by screwing the movable cutter (24) on said hollow bolt so that the movable cutter gets closer to the other cutter or draws away from it, depending on the direction of the screw.
