Disclosed is a method for making articles comprised of a body portion of an elastomeric material having a liner of an inert material covering at least a portion of the peripheral surface of said body portion including the steps of bonding a layer of elastomeric material to one face of a layer of the inert material, positioning the bonded layers in a mold cavity with the layer of inert material contacting at least a portion of the surface of a mold cavity, adding additional amounts of uncured elastomeric material to the mold cavity and curing the elastomeric materials. Also disclosed herein is a system and apparatus for making molded articles as well as the molded articles produced thereby.
A method for making articles comprised of a body portion of an elastomeric material and a liner of an inert material covering at least a portion of the peripheral surface of the body portion consisting of the steps of bonding a layer of elastomeric to one face of a layer of the inert material, forming at least one clad element of a predetermined configuration, positioning the clad element in a mold cavity with the layer of inert material contacting at least a portion of the surface of a mold cavity, adding additional amounts of uncured elastomeric material to the mold cavity and curing the elastomeric materials.
