摘要

The procedure is for manufacturing articles of molded vulcanized rubber of low density, particularly for constructing floors. A mixture of raw rubber and at least one vulcanization agent is placed in a pre-heated mold, the components themselves having been pre-heated and plastified. Time is then allowed for the vulcanization reaction to occur after which the mold is opened and the molded article is removed.
