ABSTRACT:
A process and apparatus for manufacturing a molding including a portion formed of hybrid of hard rubber and sponge rubber. The process includes steps of introducing the hard rubber and the sponge rubber into a conduit through a plurality of first ports and a plurality of second ports positioned between the first ports, thereby to form hybrid of the hard rubber and the sponge rubber in which a plurality of hard rubber filaments are uniformly embedded in the sponge rubber, and extruding the hybrid from a extrusion opening to form the hybrid portion. The apparatus includes a flow conduit for forming the hybrid, the flow conduit communicating with a sponge rubber feed pipe through a plurality of first ports and communicating with a hard rubber feed pipe through a plurality of second ports positioned between the first ports.
