Abstract

A method of fabricating molded articles composed of elastomeric material having embedded therein essentially oriented fibers, comprising the steps of fabricating a molded article with oriented fibers therein, positioning the molded article within a mold having two portions, a first mold portion defining the shape of the final molded article and a second mold portion arranged separately of said first mold portion and in communication therewith, said molded article being positioned partly in said first mold portion and partly in said second mold portion, subjecting the part of the molded article positioned in said second mold portion to a directed flow operation into said first mold portion and reorienting by said directed flow operation the fibers subjected to flow into a second fiber orientation direction differing from the fiber orientation direction of the part of said molded article positioned in said first mold portion.
