Apply upper adhesive 4 to 2. Further, before joining, a rust preventive agent is applied to the trim portion 2.
次いで、第７図に示すごとく１弾性ジョイナー３を端部
１１側の中空部１０内に挿入して１両端部１１，１２，
２１．２２を直線状に接合する。Next, as shown in FIG. 7, one elastic joiner 3 is inserted into the hollow part 10 on the end 11 side, and one both ends 11, 12,
Join 21 and 22 in a straight line.
これにより、第１図に示すごとく１両端部１１゜１２．
２１．２２を互いに接合した接合体Ａを形成する。As a result, as shown in FIG. 1, both ends 11°12.
21 and 22 are joined together to form a joined body A.
なお、上記中空シール部ｌの大きさのバラツキ等を考慮
して、上記弾性ジョイナ−３を、これに対応した大きさ
のもの１例えば直径が６〜８ｍｍのものを、３〜４種準
備しておくことが好ましい。In addition, in consideration of variations in the size of the hollow seal portion l, three to four types of elastic joiners 3 of corresponding sizes are prepared, for example, those with a diameter of 6 to 8 mm. It is preferable to keep it.
次に１本例の接合方法の作用効果につき説明する。Next, the effects of one example of the joining method will be explained.
即ち、中空部１０内に弾性ジョイナ−３を嵌挿し、中空
部ｌＯの内壁１０１とを接着剤４により接合するため、
従来の加硫接着に比して、約５分の１〜６分の１という
短時間で、接合体に接合することができる。That is, in order to fit the elastic joiner 3 into the hollow part 10 and join the inner wall 101 of the hollow part 10 with the adhesive 4,
It is possible to join the bonded body in a short time of about 1/5 to 1/6 compared to conventional vulcanization bonding.
また、かかる接合部においては、上記弾性ジョイナ−３
を、中芯としてそのまま使用するため。In addition, in such a joint part, the elastic joiner 3
to be used as is as a core.
従来の接合方法のごとく、中芯を抜き取る必要はない。Unlike conventional joining methods, there is no need to remove the core.
その理由は、上記弾性ジョイナ−３は、折り曲げ可能な
ウレタン樹脂中空発泡体等を使用していることによる。This is because the elastic joiner 3 uses a bendable urethane resin hollow foam.
したがって１本例によれば、比較的短時間でウェザ−ス
トリップを接合することができる。According to one example, therefore, the weatherstrip can be joined in a relatively short time.
また、上記両端部には１弾性ジョイナー３が跨って連結
保持されているので、接合部の変形がなく３両端部の直

ことができる。Furthermore, since one elastic joiner 3 is connected and held across the two end portions, there is no deformation of the joining portion, and the linear shape of the two end portions can be maintained as is. Therefore, it is possible to obtain a weather strip with straight joints and good appearance.
また、トリム部の端面には防錆剤を塗布しているため、
芯金が錆びることなく、耐久性に優れる。In addition, since a rust preventive agent is applied to the end surface of the trim part,
The core metal does not rust and has excellent durability.
