<p>An anatomical mask is manufactured by moulding together a relatively hard shell material (13, 170) and a peripheral cushion (15, 210) of a thermoplastic elastomer. In one embodiment a foaming agent is present in the thermoplastic elastomer and expands the cushion (15) when the mould is opened. In another embodiment two moulds have a common upper part (120) by which the moulded shell (170) is transferred between the moulds. The lower part (140) may have a groove whereby a head band (300) is formed simultaneously with the cushion (210).</p> |
