Abstract
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.
Claims9
A system for making molded articles including a body portion of elastomeric material and a liner of an inert material covering at least a portion of the peripheral surface of the body portion;
- comprising a forming station including means for bonding a layer of the elastomeric material to one face of a layer of the inert material and means for forming the laminated layers to at least one clad element configuration, a loading station including means for positioning the clad element in at least one cavity of a mold with the layer of inert material contacting at least a portion of the surface of the mold cavity, and a molding station including means for charging the mold cavity with additional amounts of uncured elastomeric material and means for curing the elastomeric material to produce the finished article.
A system as claimed in claim 11 wherein the forming station includes means for bonding the elastomeric and inert layers in sheet form and at least partially severing clad disc elements from the laminated sheet.
