Abstract

A device for expanding a synthetic material e.g. polystyrene in the form of a piece to be expanded comprises two mobile plates to open and close the mould, to each of which is attached a mould part, the mould also having a special envelope which during expansion is placed between the mould parts, and can be displaced away from the zone of the plates in a plane perpendicular to the direction of mould closure. The additional envelope makes possible the introduction of additional inserts, in the moulding, and several envelopes may be placed in a special rotary receptacle and are capable of sliding in and out of position. Discs or stiffening pins may be introduced in the envelope.
