A device and a method for widening elongated metal elements (11, 65) which move in the longitudinal direction and are planar at least in certain regions are described. The device comprises at least two clamping sections (19, 38, 49, 50) which are opposite one another and of which one is arranged and designed for clamping a first longitudinal side (22, 67) of the metal element in place and the other is arranged and designed for clamping a second longitudinal side of the metal element in place, said second longitudinal side being opposite the first longitudinal side of the metal element. The clamping sections are each provided on a support unit (15, 35, 36, 39, 40), by means of which the clamping sections, during the forward movement of the metal element, are automatically moved apart essentially perpendicularly to the direction of movement of the metal element.
L'invention concerne un dispositif et un procédé pour élargir des éléments métalliques (11, 65) allongés, se déplaçant dans la direction longitudinale, au moins en partie plats. Le dispositif comprend au moins deux sections de serrage (19, 38, 49, 50) opposées l'une à l'autre, dont l'une est disposée et conçue pour retenir par serrage un premier côté longitudinal (22, 67) de l'élément métallique et l'autre pour retenir par serrage un deuxième côté longitudinal de l'élément métallique opposé au premier côté longitudinal de l'élément métallique. Les sections de serrage sont disposées à chaque fois sur une unité de support (15, 35, 36, 39, 40), qui écarte automatiquement l'une de l'autre les sections de serrage pendant le mouvement d'avance de l'élément métallique, essentiellement perpendiculairement au sens de déplacement de l'élément métallique.
