Abstract
A method for connecting ends of a weather strip made of a rubber material and composed of a base portion and a tubular sealing portion having two chambers which are separated by a rib, includes the steps of inserting each of both ends of a core, which have such a cross-sectional shape as to fill an outward chamber of the two chambers of the tubular sealing portion and press the rib on the base portion, into the outward chamber of each of the ends of the weather strip so that the ends of the weather strip are coupled by the core, the ends of the weather strip, which are coupled by the core are set within a cavity of a mold, a rubber material is poured into the cavity, and the core is removed from the ends of the weather strip after molding.
Claims4
A method for connecting ends of weather strips, each being made of an elastic material, and having a base portion and a tubular sealing portion projecting from the base portion, the sealing portion having a rib for dividing an interior of the tubular sealing portion into a first chamber on the side of the base portion, and a second chamber on the side of a top end of the tubular sealing portion, comprising the steps of:
- coupling the ends of the weather strips by a single core in opposing relationship, both ends of said single core being inserted into the second chambers of the ends of the weather strips, respectively, said core having such a cross-sectional shape that each of said both ends of said single core fills the second chamber, and that said single core presses the rib against the base portion;
- setting the ends of the weather strips, which are coupled by said single core, within a cavity of a mold;
- pouring an elastic material into said cavity to mold a connecting portion between the ends of the weather strips;
- and
- removing said single core from the second chambers of the weather strips after molding.
