Abstract

UN MONTAJE DE RODILLO DENTADO (20) QUE PERMITE QUE UN PROYECTOR DE PELICULAS O CUALQUIER OTRO DISPOSITIVO DE MANEJO DE PELICULAS SEA FACILMENTE CONVERTIDO PARA QUE PASE UNA PELICULA QUE TIENE BIEN 4 PERFORACIONES O 3 PERFORACIONES. EL MONTAJE DE RODILLO DENTADO (20) INCLUYE UN MANGUITO CILINDRICO EXTERIOR (22) QUE TIENE DIENTES PARA ENGANCHAR LAS PERFORACIONES DE LA PELICULA Y UN MANGUITO CILINDRICO INTERIOR (24) ADAPTADO PARA QUE SE PUEDA COLOCAR DENTRO Y CASE DE MANERA ANTIGIRATORIA CON EL MANGUITO CILINDRICO EXTERIOR (22). EL MANGUITO INTERIOR (24) TAMBIEN TIENE DIENTES PARA ENGANCHAR LAS PERFORACIONES DE LA PELICULA. EL MANGUITO INTERIOR (24) ESTA MONTADO SOBRE UN EJE GIRATORIO (44) DEL PROYECTOR Y EL MANGUITO EXTERIOR (22) SE PUEDE INCORPORAR O RETIRAR DEPENDIENDO DE SI EL OPERADOR QUIERE PASAR UNA PELICULA DE 3 O DE 4 PERFORACIONES. LOS MANGUITOS EXTERIOR E INTERIOR TIENEN UN TAMAÑO TAL QUE CUANDO EL MANGUITO EXTERIOR (22), SE UTILIZA, LA VELOCIDAD A LA QUE PASA LA PELICULA ES SUSTANCIALMENTE 4/3 LA VELOCIDAD CUANDO EL MANGUITO INTERIOR (24) SE UTILIZA SOLO.
