Abstract
A process for the compression moulding of hollow thermoplastic bodies in a single operation involves the steps of depositing a first sheet of heated thermoplastic material on a lower mould half that exhibits depressions or cavities below the joining plane of the mould halves, placing a compressed air supply pipe on top of the sheet, depositing a second sheet of heated thermoplastic material over the first sheet and over the pipe, while introducing air at a pressure and/or flow rate sufficient to keep the said sheets apart, closing the mould so that the sheets are compressed together and join along predetermined portions in the joining plane of the mould halves, and introducing compressed air at sufficient pressure to mould the sheets into the mould cavities. <IMAGE>
