Abstract: Machine for the silk-screen printing of flat articles such as sheets of glass (2) and the like, comprising at least four fixed uprights (10) supporting horizontal parallel beams (20) on which a bridge (30) carrying the printing means (40) is movable, and a surface (3) for resting the glass (2), said machine comprising an apparatus (100; 1000) for gripping and centring the glass (2) with respect to the fixed printing screen (4).

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 sett

Abstract: An apparatus for the automatic separation along predetermined bending fracture lines in basic ceramic platelets of hybrid electronic circuits includes a support plate provided with grooves on its lower face defining bending lines juxtaposed with the fracture lines of the platelet urged against an upper face of plate by upper pressing members being in contact with each of single elements of the platelet defined by the fracture lines and lower retractable members controlled in a predetermined sequence for successive bending of the plate and the platelet subdivided in a plurality of single elements.
