Abstract (en)
Panel bending machine for bending sheets (12),comprising a support plane (8), an upright structure (24), at least one sheet-blocking device (28) able to constrain the sheet (12) in relation to said support plane (8), at least one blade-holder device (32) fitted with blades (36) suitable to perform bending operations of said sheet (12), vertical drive means (40) which move both the sheet-blocking device (28) and the blade-holder device (32) in a vertical direction (ZۥZ), substantially perpendicular to said support plane (8). Advantageously, the panel-bending machine (4) comprises transversal movement devices (80) mechanically separate from the vertical drive means (40), to confer to the blade-holder head (68) totally disengaged and independent vertical and transversal movements. The transversal movement devices (80) comprise a pusher (84) connected to the blade-holder head (68) by means of a jointed parallelogram kinematism (88).
