Abstract:
The pressure beam is adapted to be used in sawing machines for cutting workpieces such as panels or packs of panels (P), of the type comprising a workpiece support table (L) having a straight longitudinal slot defining a cutting line and a sawing tool (Z) movable along the cutting line. The pressure beam is arranged above the workpiece support table (L), extends along the whole length of the cutting line and consists of two pressure elements (R, R min ) arranged at both sides of the cutting line, parallelly thereto. Means are provided for raising and lowering each pressure element (R, R4) independently with respect to the other pressure element, and traverse means are provided for laterally moving the said pressure elements (R, R min ) and consequently varying the distance of the pressure elements (R, R min ) with respect to the cutting line located between them.
