Abstract

Aparato para revelar planchas de imprimir, que comprende una pluralidad de puestos de tratamiento, estando diseñada cada puesto momo una unidad estructural (por ejemplo 1) que puede ensamblarse con otras unidades estructurales (por ejemplo 2 y 3) para formar el aparato, y que incluye además unos cilindros superiores e inferiores dispuestos a pares, particularmente en una posición horizontal, que sirven para transportas las planchas de impresión y, en caso de necesidad, para exprimir cualquier líquido residual adherido a las planchas de impresión, que incluye además un cojinete situado en cada extremidad de cada cilindro superior, que puede ser elevado y bajado respecto al cilindro inferior y que puede ser accionado por medio de un sistema de palanca basculante, caracterizado porque una cabeza bifurcada montada de manera pivotante (por ejemplo 31) dotada de un brazo superior y de un brazo inferior (33 y 34) está prevista para acoplarse con los cojinetes de (8 a 11) de los cilindros superiores (4 a 7) , extendiéndose el eje oscilante(32) de la cabeza bifurcada paralelamente a la dirección de transporte (T ) de las planchas de impresión y ejerciendo el brazo superior (33) de la cabeza bifurcada una presión desde la parte superior sobre el cojinete (15) por medio del sistema de palanca basculante (26 a 30) cuando el cojinete está en posición baja, y soportando el brazo inferior (34) de la cabeza bifurcada el cojinete cuando este último está en posición alta, caracterizada además porque una primera extremidad de cada sistema de palanca basculante está conectado con la cabeza bifurcada (por ejemplo 31) y una segunda extremidad de cada sistema de palanca basculante está conectada con un eje de control giratorio (19) común a todos los sistema de palanca basculante y que está igualmente soportado paralelamente a la dirección de transporte (T) de las planchas de impresión.
