Abstract

Method for obtaining body belts made of reinforced alveolar plastic material in the car industry, of the type using a heating by means of a high frequency electric field, characterized in that there is introduced directly into a mold fitted with high frequency electrodes and having the dimensions corresponding to the finished product required a sufficient quantity of pulverulent or granular mixture of PVC and a foaming agent in order to obtain said finished product thereafter, the reinforcing element is introduced on or in the pulverulent or granular mass, the mold is closed and subjected to a high frequency field during the time required for melting the PVC and for the gas evolution resulting from the decomposition of the foaming agent the resultant finished product is removed from the mold.
