Abstract
A sheet of a cross-linkable and foamable polyolefin resin is thermally treated on an endless conveyor belt formed of a plain weave wire net. A plurality of parallel, spaced apart rolls are disposed in a direction perpendicular to the direction in which the conveyor belt runs for supporting engagement and rolling contact with the conveyor belt to maintain the flatness of the conveyor belt.
