Abstract

L'invention concerne un dispositif pour introduire de façon régulière et réglée des bandelettes d'un mélange de base de caoutchouc dans l'ouverture de chargement d'une machine à vis. A une distance bien définie du cylindre 27 de la machine à vis, est monté un volet 11 pouvant librement pivoter dans la trémie 10 et qui est associé à un aimant permanent, formant, avec un autre aimant permanent, un interrupteur de proximité commandant alternativement la marche de la bande convoyeuse 4 ou de l'appareil 5 de découpage fournissant des bandelettes à traiter dans la machine à vis. Application : régulation de l'alimentation en bandelettes d'une machine à vis pour le traitement d'un mélange de caoutchouc.
