<p>An apparatus (1) for making a spectacle frame (2) made of thermoplastic material comprises an oven configured for heating a sheet (3) of the thermoplastic material to a predetermined temperature at which the material softens; a first and a second half-mould (5, 6) having opposite transversal faces (7, 8), at least one the half-moulds being able to move longitudinally towards the other to form a compression space for the softened sheet (3) placed therein. The transversal face (8) of the second half-mould (6) comprises at least one recess (9) configured in such a way that compressing the sheet (3) causes a plastic deformation by migration of material from the bulk of the sheet (3) into said at least one recess (9), generating at least one projection in the sheet which is positioned at frame (2) nose pads (21) and/or side edges (22).</p> |
