FORMING A WEATHERSTRIP

摘要

A method for forming a weatherstrip includes extruding a compound formed of 1-10 weight of polyglycidyl methacrylate having an epoxy group in the molecular structure thereof added per 100 parts of a rubber compound formed of SBR/EPDM. As the compound is extruded from the extruder, a urethane coating material is supplied to a nozzle to accomplish coating of an article concurrently with forming thereof. The extruded article is then vulcanized to assure good sealability.
