Abstract

A method of moulding thermoplastic sheet material (17) includes: floating the sheet material (17) on a liquid (12), the density of the liquid (12) being greater than that of the sheet material (17); maintaining the liquid (12) at a temperature at which the sheet material (17) is plastic, and bringing a mould (14) progressively into engagement with the sheet material (17), so that the sheet material (17) is deformed to the shape of the mould (14).
