Abstract: A sawing machine for cutting workpieces such as panels or packs of panels (P) comprises a horizontal workpiece support table (A) having a straight longitudinal slot (L) defining a cutting line, a sawing tool (S) movable along the cutting line and a longitudinal pressure device arranged above the workpiece support table and extending along the entire length of the cutting line. The pressure device consists of two pressure beams (1, 1') arranged at both sides of the cutting line, parallel thereto. Each beam can be raised and lowered independently of the other in relation to the workpiece support table in order to clamp thereon the workpiece to be sawed or to contact the surface of the support table.
