PROCESS AND EQUIPMENT FOR MANUFACTURING A PLASTIC HOLLOW BODY FROM TWO SHEETS

摘要

Process for manufacturing a plastic hollow body by moulding two sheets of molten plastic in a mould comprising two cavities, said process comprising the following steps : a) two molten plastic sheets are manufactured; b) these sheets are introduced between the mould cavities; c) the mould is closed and the hollow body is manufactured by conforming these two sheets to the mould cavities. In this process, when the mould is closed, a device that is attached to this mould automatically stretches the sheets and/or smoothes the sheets. Equipment for carrying out such a process.
