Abstract

Alimentation du papier dans les machines à écrire à pla­ tine cylindrique tournante. Afin d'assurer simultanément le parallèlisme entre les axes des rouleaux d'alimentation et l'axe de la platine et de répartir uniformément les forces de contact exercées par les rouleaux sur la platine, les axes (26, 28) portant les rouleaux d'alimentation (30, 32) sont montés sur un châssis (22) couplé par l'intermédiaire d'une rotule (36) à un élément de support (16). Ce dernier est couplé au châssis principal (10) de la machine de façon à exercer une force rappelant le châssis porte-rouleaux (22) vers la platine. Dispo­ sitif utilisable notamment dans les machines à écrire à platine cylindrique tournante se déplaçant ou non en translation dans la machine.
