The equipment comprises a moulding element (16) having a working surface (18) against which a previously-heated sheet (12) of thermoplastic material is urged. The equipment comprises at least one movable element for defining a cavity (38) with an undercut cross section which, in use, encloses a portion of the sheet (12) to be moulded and compressed-air supply means (36) which bring about the deformation of at least one portion of the sheet (12) by means of a jet of compressed air. |
