A method is provided for joining two pieces (10, 12) of elastomeric fabric together without the need for sewing or stitching the seam. This is accomplished by cutting piece (10) to form a first edge (16) having first geometric pattern (20), cutting piece (12) to form a second edge (18) having second geometric pattern (22) which corresponds with pattern (20), applying a bonding agent to lateral surface (24) of pattern (20), applying a bonding agent to lateral surface (24) of pattern (22), and mating edges (16, 18) to create intersecting seam (14) between pieces (10, 12). Seam (14) is immobilized to allow the bonding agent to set. Tape (26) may be placed on one or both sides of seam (14) for additional strengthening.

L'invention concerne un procédé permettant d'assembler deux pièces (10, 12) de tissu élastomère sans avoir à les coudre ou à les surjeter. Pour ce faire, on coupe un pièce (10) de manière à former un premier bord (16) présentant un premier motif géométrique (20) ; on coupe une pièce (12) de manière à former un deuxième bord (18) présentant un second motif géométrique (22) correspondant au motif (20) ; on applique un agent de liaison sur la surface latérale (24) du motif (20) ; on applique un agent de liaison sur la surface latérale (24) du motif (22) ; et on place les bords (16, 18) côte à côte de manière à créer une jointure (14) d'intersection entre les pièces (10, 12). La jointure (14) est immobilisée pour permettre le durcissement de l'agent de liaison. Pour renforcer la jointure, on peut disposer un ruban adhésif (26) sur l'un ou les deux côtés de la jointure (14).
