Abstract

PURPOSE:To reduce number of processes and to attempt to simplify a manufacturing apparatus, by treating products filled with sealing materials in a different process from the molding of a weatherstrip itself by means of simultaneous extrusion molding. CONSTITUTION:A belt-like core metal 2 where a lot of slits are punched out is fed to an extrusion molding machine 11, and a solid rubber material 12 constituting a welt part 1 is extruded so as to cover the core metal. At the same time as this extrusion, a rubber material 14 for a seal part with a string-shape is extruded along the inside of the bottom part of the welt part 1. This rubber material 14 for the seal part has a composition where no or a very small amt. of vulcanizing agent and vulcanizing accelerator are compounded and are not therefore vulcanized at this specific temp. Then, the product thus molded by multiple extrusion is introduced in a vulcanizing bath 15 after coming out of the extrusion molding machine 11. In this vulcanizing bath 15, it is heated at a specific temp., e.g. 120 deg.C and a weatherstrip 10 is thereby completed.
