ABSTRACT:
An automatic machine for the production of rounded bevels at the corners of flat sheets, comprising a device (20) for the support and transfer of a sheet (3), hinged to fixed frame (10) of the machine and capable of rotating in relation thereto around an axial parallel to the feed direction, means (40) for stopping the feeding of such sheet, a means (30) holding sheet (3), hinged to fixed frame (10) and capable of rotating in relation thereto around an axis of rotation (32a) perpendicular to the plane of sheet (3), a work tool (50) integral with fixed frame (10) in relation to which it may be made to rotate via appropriate means (52, 52a), and means (60 ) for unloading sheet (3) on completion of the work, the axis of rotation of such means (30) for holding sheet (3) being capable of being moved in programmable settings with respect to a reference line parallel to lower edge (3a) of sheet ( 3) and the stopping surface of such means (40) for stoppage of movement being capable of being moved in programmable settings with respect to axis of rotation of the holding means so as to establish the desired radius of curvature.
