Abstract

Appts. for continuously producing an insulation-protection sheet for packaging articles, e.g. glass containers and photographic appts., consists of >=1 level extrusion heads with >=1 independent outlets with adjustable apertures and individual heat controllers, >=1 shaping rollers situated close to and facing the extrusion heads. Gives sheets combining low density, and excellent heat insulation and impact resistance.
