The sheet workpiece positioning device (10) is designed for supporting a sheet workpiece (5) along three adjacent sides thereof, by means of opposing supporting members (12 and 14) and a supporting member (13) set at right angles to the former supporting member. Preferably, at least one of the former supporting member (12 and 14) is designed to be able to slide along the latter supporting member (13). The sheet workpiece is gripped by a plurality of independent gripping devices (19, 119 and 20), evenly spaced out, side by side, and held, respectively, by the supporting members (12, 13 and 14). The gripping devices, which are long and thin, comprise a gib (39) and a front edge (45) of a U-shaped elastic member (46). An upper prong (48) of the U-shaped elastic member, interacts with an angle plate (53) held fixed by the gib and set so as to move the second gripper jaw provided on the upper prong towards the first gripping jaw (45) of the gib (39), following the traction of the U-shaped elastic members (46). |
