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. Paper feed in pla typewriters cylindrical rotating tine. In order to simultaneously ensure parallelism between the axes of the feed rollers and the axis of the stage and evenly distribute the forces of contact exerted by the rollers on the plate, the pins (26, 28) carrying the feed rollers (30, 32) are mounted on a chassis (22) coupled via a ball joint (36) to a support element (16). The latter is coupled to the chassis main (10) of the machine so as to exert a force recalling the roller holder frame (22) towards the plate. Available sitive usable in particular in platinum typewriters cylindrical rotating or not moving in translation in the machine.
