<p>The invention relates to a sawing machine of the type comprising a horizontal workpiece support table (1) presenting a straight longitudinal slot (2) defining a cutting line, a sawing tool (4) mounted on a carriage (6) reciprocably movable along a path parallel to and beneath the cutting line, and a longitudinal pressure bar (3) arranged above the said workpiece support table (1) which pressure bar (3) extends along the whole length of the cutting line and can be raised and lowered with respect to the said workpiece support table (1) so as to be capable of blocking thereon the workpiece (P) to be sawed. In the sawing machine there is provided a first safety device, consisting of a protective apron extending along both sides of the cutting line, said protective apron being formed by a plurality of slats (10) hingedly mounted, with possibility of swinging through a predetermined angle of oscillation, on longitudinal apron rods (7). A second safety device is further provided, consisting of a longitudinal inner contact bar (14) and a longitudinal outer contact bar (13) mounted on each side of the pressure bar (3) hanging therefrom with possibility of vertical movement. The said inner and outer contact bars (13, 14) are adapted to cooperate, following to their lifting, with control devices (19, 20) acting on the control circuit of at least the cutting saw (6).</p> |
