In a sawing machine for cutting panels (P) and the like, of the type in which said panels (P) are supported on a horizontal supporting table (A) and a main circular saw (S) mounted on a movable carriage (C) effects the cutting in a vertical plane and moves across said supporting table (A) along a horizontal cutting line, there is provided a grooving device for making a groove or incision in the edge of said panels (P) at the line of exit of said circular saw (S) out of said panels (P). The grooving device comprises a rotary grooving tool (30) mounted on the same carriage (C) carrying the main circular saw (S). The rotary grooving tool (30) is mounted on a movable side (12) of an articulated parallelogram structure (1,13,11,12 - 9,10,14,15) mounted on the carriage (C) by means of another side (1) rigidly secured thereto. An air-operated jack (17) is provided for moving the said articulated parallelogram structure from a rest position in which the grooving tool (30) is inactive, to a working position in which the grooving tool (30) engages the panels (P), and vice versa. |
