ウェザストリップ本体１は取付は基部３と中空シール部
フとを備えている。さらに、区側では、Ｕ時形断面の車
外側端に水切りリップ８が形成されている。The weatherstrip main body 1 includes a mounting base 3 and a hollow seal portion. Further, on the compartment side, a draining lip 8 is formed at the outer side end of the U-shaped cross section.
ここで、取付は基部３は、インサート４が埋設されたＵ

お、口側中Ｔはトランクリッドである。In addition, since the hollow seal part is made of a highly foamed rubber material (which conforms well to the contact surface), the corner part C (particularly when it is made of an integrally extruded material), as shown in FIG. As shown in the figure, it is easy to deform (the two-dot chain line indicates the extruded shape), and there is a possibility that the set sealer cannot be obtained. Note that the middle T on the mouth side is the trunk lid.
そこで、従来は、核部における変形を防止するために、
補強充填部材（通常、エチレンプロピレンゴム性スポン

）。The method of incorporating this reinforcing filling member 1o into the hollow seal portion 7 is to insert the reinforcing filling member (1o) from one end of the extrusion before connection.
A common method was to press fit the spacer 10 into a predetermined position using air jetted from a nozzle 11 (see FIG. 7).

ものである。Means for Solving the Problems> The weatherstrip manufacturing method of the present invention includes a mounting base and a hollow seal part, and a reinforcing filling member is built in a predetermined part of the hollow seal part to prevent deformation. When manufacturing a weatherstrip, the reinforcing filling member is formed by inserting an injection needle into the outer surface of a predetermined portion of the hollow seal portion, injecting a reaction-curing liquid foam material into the portion, and foaming and curing the material. This method solves the above problems.
〈実施の態様〉
以下、本発明の製造方法を、口側に基づいて説明をする

の説明の一部を省略する。<Embodiment> The manufacturing method of the present invention will be explained below based on the oral side. The same parts as in the conventional example are given the same reference numerals and a part of the explanation will be omitted.
まず、取付は基部３と中空シール部７とを備えた押出物
Ｗを成形する。即ち、インサート４、ソリッドゴム材料
、スポンジゴム材料を押出機１３を用いて共押出をし、
加硫槽１５を経て加硫を行ない、取付は基部を曲げ機１
７で０字型に曲げ加工を行ない、裁断機１９により所定
長に裁断する、ここで、使用するゴム材料としては、通
常、エチレンプロピレンゴム系、クロロブレン系のゴム
を使用する。First, for attachment, an extruded product W including a base portion 3 and a hollow seal portion 7 is molded. That is, the insert 4, solid rubber material, and sponge rubber material are coextruded using an extruder 13,
Vulcanization is performed through a vulcanization tank 15, and the base is bent using a bending machine 1 for installation.
The rubber material used here is usually ethylene propylene rubber or chlorobrene rubber.
つぎに、該押出物Ｗの両端部を接着剤等により接続し、
第１図に示すような環状とする。なお、９は接続部であ
る。Next, both ends of the extrudate W are connected with adhesive or the like,
It is made into an annular shape as shown in FIG. In addition, 9 is a connection part.
そして、該環状のコーナ部Ｃにおいて、口側の如く、注

入針２２の外径及び孔径は、それぞれ、１〜５ ｍｍ、
０．５〜４．５ ａｒｍとする。Then, in the annular corner portion C, as on the mouth side, a liquid material is injected into the hollow seal portion 7 using the injection gun 21, and is foamed and hardened to form the reinforcing filling member 10A. That is, the injection needle 22 is inserted from the outer surface and the reaction-curable liquid foam material is injected into the area. At this time, since the injection needle 22 is thin and the hollow seal portion 7 is formed of a rubber material,
When the injection needle is removed, the hole that was forcibly expanded by the needle shrinks and closes, leaving almost no puncture marks.The outer diameter and hole diameter of the injection needle 22 are 1 to 5 mm, respectively.
0.5 to 4.5 arm.
注入針２２を抜く時期は、上記の如く孔は針をぬいた後
、閉じるので、所定量の材料を注入完了直後でよく、発
泡硬化するまで待っている必要はない。The injection needle 22 can be removed immediately after the injection of a predetermined amount of material is completed, and there is no need to wait until the foam hardens, since the hole closes after the needle is removed as described above.
ここで、使用する液状発泡材料としては、例えば、−波

Specifically, "Aerofloss" (registered trademark; Nippon Polyurethane Kogyo@) and the like can be used as the former, and "Shin-Etsu Silicone KE521" (registered trademark; Shin-Etsu Chemical Co., Ltd.) and the like can be used as the latter.
なお、補強充填材の形成は、押出物の両端部を接続して
環状にする前でもよい。Note that the reinforcing filler may be formed before connecting both ends of the extrudate to form an annular shape.

シール部にも必要により、本発明の方法により補強充填
部材を内蔵できる。When molding, the connecting parts between the hollow seal parts of the extrudate should be formed hollow to improve the surface texture. Therefore, if necessary, a reinforcing filling member can be built into the hollow sealing part of the molding part by the method of the present invention.

記のような作用・効果を奏する。<Actions and Effects of the Invention> As described above, the method for manufacturing a weather strip of the present invention includes the following steps:
When manufacturing a weatherstrip that includes a base and a hollow seal part and has a reinforcing filling member built into a predetermined part of the hollow seal part to prevent deformation, the reinforcing filling member is attached to a predetermined part of the hollow seal part. This method is formed by inserting an injection needle into the outer surface of the area, injecting a reaction-curing liquid foaming material into the area, and foaming and hardening it, so that it has the following functions and effects.
従来の如く、補強充填部材を空気で圧入して、内蔵する
方法でないため、当該従来方法に比して、工数を大幅に
削減できるとともに、所定位置に確実に補強充填部材を
内蔵でき、補強充填部材の位置決めを考慮する必要がな
い。Since the reinforcing filling material is not built in by press-fitting it with air as in the past, the number of man-hours can be significantly reduced compared to the conventional method, and the reinforcing filling material can be reliably built into the specified position, making it easier to fill the reinforcing filling material. There is no need to consider the positioning of members.

おいて本発明方法より劣る。In addition, in JP-A No. 82-258826, the same person as the present inventor proposed a technique in which a reinforcing filling member is also molded and inserted at the same time as the extrudate is molded, and the extrudate is vulcanized and foamed at the same time as the extrudate is vulcanized. ing. However, in this method of manufacturing weather strips, the structure of the extruder is complicated, and the reinforcing filling member cannot be built in after the extrudates are connected in an annular shape. inferior to method.
