<p>A method and an apparatus for applying a cover sheet (12) of plastic material to the surface (18) of a mould (10), during the moulding of panels and/or of plastic pieces. The cover sheet (12) is pneumatically held and stretched by a support frame (11) provided with a sheet clamping groove (35), which peripherally extends for at least part or the edges of the mould (10); the support frame (11) is provided with an air suction chamber (26) connected to the sheet clamping groove (35) by at least an air suction slot (32, 34) which opens on the bottom of the groove (35). The pneumatic support frame (11) for the cover sheet (12) and the mould (10) are movable between each other for pneumatically adhering the cover sheet (12) to the edges and the internal surface of the mould (10). <IMAGE></p> |
