Abstract

L'invention concerne un bobinoir à rouleau de contact qui améliore l'état antérieur de la technique de machine à bobiner, dans laquelle on pallie une vitesse et une longueur accrues par division du rouleau de contact dans la direction axiale afin d'élever le point de résonance, mais au préjudice de la maintenabilité et avec l'inconvénient d'une augmentation du nombre d'éléments à assembler en raison même de la division. En l'occurrence, il n'est pas nécessaire de retirer une enceinte commune placée au milieu lorsque le rouleau de contact est retiré, ce qui diminue le nombre d'éléments à assembler et supprime la fabrication ou la gestion d'un gabarit onéreux qui assure la précision de centrage au moment du réassemblage. Sans retrait de l'enceinte intermédiaire, le repositionnement de l'enceinte commune n'entraîne aucun décentrage. Enfin, seul le rouleau de contact sur le côté bâti de machine peut être remplacé facilement, et l'efficacité de maintenance s'en trouve largement renforcée.
