PROBLEM TO BE SOLVED: To reduce the number of parts and to shorten the time for assembling by a method wherein each required length of extrusion-molded seal materials at a butt joint position of transverse and longitudinal sash materials is peeled off, and after both sash materials are welded and cooled, the extrusion-molded seal materials are returned to its original position and the gap between both seal materials are connected with an in-mold molded seal material. SOLUTION: Sash materials 30 and 40 are obliquely cut on their connecting side and under a condition where parts in the vicinity of connecting parts of seal members 10 and 20 of extrusion-molded products (approximately 30mm in the longer direction from the connection end face between Y-Y region) are peeled off, the obliquely cut inclined end faces are butted and welded together. An in-mold molded seal material 60 is formed in the gap between these end faces. In addition, after welding, it is kept on cooling and the part between the Y-Y region where the seal members 10 and 20 are peeled off is returned to its original condition by arranging an adhesive to bond it on the sash materials 30 and 40. As the result, even when temp. in the neighborhood of the welded part of the sash materials 30 and 40 is elevated during welding, deterioration of seal members 10 and 20 can be avoided and in addition, they are integrated with the sash materials 30 and 40 and the number of parts can be reduced. |
