<p>A bending machine comprises a frame (10), havina a main side (10') in which a bendina head is provided includina three bender rollers (11, 12, 13), two rollers (11, 12) of which have fixed axes of rotation, one roller (13) havina a vertically displaceable axis of rotation, as it is mounted on a slider (13') provided with a linear positionina system. Further, the bendina machine comprises a motor and reduction gear unit (27) driving one or more bender rollers (11, 12, 13), thrust rolls (14, 15), and a double-acting cylinder (34) with a driving rod (34b) of displacement of said slider 113'). The cylinder (34) has its cylinder body (34a) mounted inside the frame (10) below said bending head, so that a work surface (C), thus remaining free on said main side (10'), is provided with means adapted to support a tool on said work surface. <IMAGE></p> |
