Claims6
A method of making a weatherstrip gasket assembly for an automobile embodying an elastic member, with a supporting metal part of said automobile having a receiving surface, wherein said method comprises the following steps:
- a) fabricating a sole-piece formed by a beam having at least an outside portion and a fixing member formed from a material which melts upon heating, and with at least an engaging portion, in such a manner that at least said engaging portion of said fixing member melts upon heating;
- b) positioning said elastic member on said outside portion of said beam;
- c) assembling said outside portion of said sole-piece with said elastic member with said fixing member being spaced from said elastic member, to form a unitary one-piece assembly consisting of said elastic member and said sole-piece;
- d) positioning said unitary one-piece assembly on said receiving surface of said supporting metal part of said automobile by contacting said engaging portion with said receiving surface;
- and
- e) applying induction heating to said receiving surface for melting said engaging portion and forming a bond between said engaging portion and said receiving surface.
