in order to reduce the cost of weather seal having a core or carrier which acts as an embedded support for the rubber - like sealing material , the carrier is first contained within a substrate of low - cost rubber material , which may be applied to the core by extrusion of a substrate of recycled , reground rubber , preferably epdm rubber which may include a thermoplastic olefinic material as a binder . this substrate is cohesive with an overlaying covering of uncured elastomeric material , which may be extruded over the substrate - encased carrier . the carrier , which may be sold separately or encased in the substrate , is provided to enable to the weather seal to be compressed or bent . reinforcement elements are attached to the wire loops of the carrier , without knitting to the wire loops . the loops of the wire carrier are guided into and held in grooves in a wheel . feed screws tangential to the wheel compress the loops . the compressed loops are brought to a process station where the reinforcement elements are applied and attached . the use of recycled cured material in a substrate and the replacement of yarn attached to a wire carrier by knitting , with overlaying reinforcement elements provides cost savings over conventional weather seal which is significant since such weather seal is used in large quantities in the automotive industry .
