悪《するという問題点がある。“Problems to be Solved by the Invention” Among the sunroof weather strips formed by the above-mentioned conventional molding method, in the former where the entire corner portion 2 is molded with a mold, the corner portion 2 is already formed before vulcanization, Although deformation during vulcanization is slight and installation is relatively easy, there is a problem in that the manufacturing cost is high.
f&4f, in which a rubber core or spring core is inserted into the hollow part 1a, bent, and vulcanized in the mold, is not fully restrained during molding, and is deformed. Sagging or shrinking...In other words, the inner narrow part 2a is crushed, and the width of the weather strip corner part 2 becomes narrower than the width of the weather strip corner part 2 (1). <(J>j), and the width h of the lip piece 2b of the rectangular part 2 is narrower than the width H of the lip piece 1b of the straight part l (H>h)...Installation There is a problem that it is difficult to match the panel opening edge 3, and it takes time and effort to attach the sunroof body 4, and it also deteriorates the appearance.

ものである。<Means for solving the problem> This will be explained with reference to the drawings. In order to achieve the above object, the hollow weather strip forming method according to the present invention vulcanizes and re-shapes an unvulcanized semi-finished product formed into a hollow shape by extrusion molding, and forms the corner portion 2 by: This method consists of fitting an unvulcanized semi-finished product formed into a hollow shape into a corner mold 5 and introducing pressurized air into the hollow portion 2a.

ストリップを製作することができる。<Function> During vulcanization and re-molding of a semi-finished product formed into a hollow shape, pressurized air P is introduced into the hollow portion 2a, so that the hollow Fli 2 at the time of extrusion and shaping. The cross-sectional shape of + is held h'dr, and the corner part 2 of the weather strip is set,
It is possible to produce a weather strip that prevents shrinkage, fits well with the sunroof body 4, roof panel opening edge 3, etc. when installed, and has an excellent appearance.
