The invention relates to a device for deviating strips, in particular metal strips in a coiler installation, from an initial guide route (1) to a final guide route (2) and vice versa. Said device comprises a driver mechanism (3) comprising a pair of driver rollers (4, 4') and actuating members that are located downstream in the displacement direction (B) of the belt, a separator device (5) that can be pivoted towards the initial or final guide route (1, 2) and a guide table (6), which is pivotally mounted underneath the separator and can be pressed against the lower driver roller (4') to act as a skimmer. The aim of the invention is to optimise the deviation of the strips. To achieve this, the upper and lower faces of the separator device (5) are convex and said device is mounted in an articulated manner at the delivery end of an associated roller conveyer (7, 7') for transporting the strips, in such a way that it exposes the initial guide route (1) in the raised position, lying against the upper driver roller (4) to act as a skimmer and the guide table (6) is concave to adapt to the lower face of the separator device (5). A respective actuating organ, e.g. a hydraulic unit (8, 8') is allocated to both the separator device (5) and the guide table (6).

L'invention concerne un dispositif pour faire changer la direction de bandes, notamment de bandes métalliques dans une installation d'enroulement, et les faire passer d'une ligne de guidage initiale (1) à une ligne de guidage finale (2) et inversement. Ce dispositif comprend un entraînement (3), composé de deux cylindres d'entraînement (4, 4') et d'actionneurs disposés en aval du sens de déplacement de la bande (B), un dispositif de séparation (5) orientable contre la ligne de guidage initiale ou finale (1, 2), et une table de guidage (6), montée pivotante en-dessous du dispositif de séparation et appuyant en tant que racloir contre le cylindre d'entraînement inférieur (4'). L'invention vise à optimiser la déflexion des bandes. A cet effet, les faces supérieure et inférieure du dispositif de séparation (5) sont convexes et le dispositif de séparation est, en fin de processus, articulé relativement à un convoyeur à galets (7, 7') associé pour le transport des bandes de telle sorte que, lorsque ledit dispositif est relevé, il libère la ligne de guidage initiale (1), il appuie contre le cylindre d'entraînement supérieur (4) pour agir comme racloir, la table de guidage (6) étant de forme concave pour s'adapter à la face inférieure du dispositif de séparation (5). A ce dispositif de séparation (5) comme à la table de guidage (6) est associé un organe d'actionnement, par ex. une unité hydraulique (8, 8').
