Abstract

On prévoit un dispositif de retenue pour la production d'une action de freinage dans un grand nombre de bandes de feuillard métalliques enrouler. Ce mécanisme comprend au moins un moteur linéaire à champ d'ondes progressives pour produire l'action de freinage. Le moteur linéaire reçoit, à l'encontre des forces de flexion engendrées pendant le fonctionnement, une précambrure qui disparaît pendant la marche, si bien que l'entrefer entre le moteur linétaire et le plan des bandes reste identique quant à la largeur, de même que sont égales, par conséquent, les forces de freinage agissant sur chaque bande de feuillard.
