Abstract

Mouldings are produced by thermoforming strips or sheets of thermoplastic matl. brought to deformation temp., with redn. of the thickness of the matl. in the region of the moulding and by cooling the moulded strips or sheets and cutting the mouldings from the surrounding residual matl. still having the original thickness. The strips or sheets which are at deformation temp. prior to thermoforming are pre-cooled in zones outside those to be formed into mouldings. Process helps to reduce the cooling time after thermoforming, the major component of which is the time to cool the undeformed zones of original thickness.
