Abstract

Système assurant un centrage de la bande sans fin. Il comprend un premier rouleau d'entraînement 64, un deuxième rouleau 70 dont les extrémités 74, 78, sont évasées, un troisième rouleau 68 monté sur des bras-supports pivotant 84, 86 contraint par des ressorts 90, 92, tous ces rouleaux étant parallèles en fonctionnement normal, de sorte qu'un glissement de la bande 62 vers une extrémité évasée du deuxième rouleau entraîne le basculement du troisième rouleau qui n'est alors plus parallèle aux autres, ce qui provoque le déplacement latéral de la bande vers l'autre extrémité des rouleaux jusqu'à ce qu'elle soit à nouveau centrée et le parallélisme des rouleaux rétabli. Application aux tireuses magnétiques.
