Abstract

La propiedad y explotación exclusivas de un transportador de cintapara el transporte de hojas sensibles a través de máquinas fotográficas automáticas y semiautomáticas que comprende dos cintas continuasque se adhieren una a otra en una parte de su movimientoentre las cuales son cogidas las hojas al principio y soltadas al final del recorrido de contactocaracterizado por el hecho de poseer cada cinta amplia sección en forma de U y de ser mantenidas la hojas entre dos bordes paralelos entre los ramos opuestos de las dos secciones en forma de Uestando provisto el nervio de las secciones en forma de U de grandes aperturas de forma que las cintas conservan su flexibilidad.The exclusive ownership and exploitation of a belt conveyor for the transport of sensitive sheets through automatic and semi-automatic photographic machines that comprises two continuous belts that adhere to each other in a part of their movement between which the sheets are picked up at the beginning and released at the end of the contact path characterized by the fact that each strip has a wide U-shaped section and the sheets are held between two parallel edges between the opposite branches of the two U-shaped sections, the rib of the U-shaped sections being provided with large openings so that the tapes retain their flexibility.
