Abstract

A continuous process for effecting further expansion of cellular thermoplastic sheet material comprises moving a band of the sheet material relative to a radiant heat source adapted in any one position of the band to heat a transverse strip portion of the band whilst supporting said portion of the band by means of a supporting element which is in contact with the band face of the band opposite to the radiant heat source. The specified cellular thermoplastic resin sheet material is cellular polystyrene sheet.
