Abstract
A process of extrusion molding plasticized vulcanizable or cross-linkable rubber or synthetic resin materials, comprising the steps of heating said materials to an elevated temperature in a short time immediately before a molding die and vulcanizing or cross-linking the materials in the manner of maintaining said elevated temperature substantially while the materials are passing through the die or for a while after they have passed through the die, thereby obtaining mold goods.
