Abstract

L'invention concerne un dispositif qui permet de relier des bandes métalliques (M1, M2) entrant successivement dans une installation de traitement de bandes (A) et qui comprend deux poinçons de coupe (4, 5) chacun pourvus d'un tranchant (18-20) associé à un tranchant (18, 20) de l'autre poinçon de coupe (4, 5). Les poinçons de coupe (4,5) peuvent être animés d'un mouvement de coupe le long d'un axe de coupe (S) afin de faire une découpe dans deux parties d'extrémité superposées des bandes métalliques (M1, M2) et de réaliser une liaison permanente par déformation d'une zone adjacente. Les tranchants (18-21) des poinçons de coupe (4, 5) définissent, lorsqu'ils se trouvent en position équivalente par rapport à l'axe de coupe (S), une fente de coupe (22, 23) s'étendant dans le sens transversal (Q) et présentant, dans un sens de largeur (B) orienté perpendiculairement au sens transversal (Q) et à l'axe de coupe (S), une largeur de fente (BS). Selon l'invention, une trajectoire de coupe optimale est obtenue par le fait que les tranchants (18, 20; 19, 21) forment un angle aigu (ß) avec le sens transversal (Q) vu dans la direction de coupe et par le fait que les poinçons de coupe (4, 5) peuvent être réglés l'un par rapport à l'autre pour ainsi modifier la largeur de fente (BS) dans le sens transversal (Q) de la fente de coupe (22, 23).
