Abstract

La presente invención se relaciona con un método para limpiar un baño de electrodeposición catódica en un equipo continuo, donde un palé (1) conectado a una instalación de transporte es transportado a través del baño de electrodeposición catódica, y en donde el palé (1) comprende un medio de filtrado (2); el medio de filtrado (2) está sujeto al palé (1) por medio de al menos un elemento de conexión movible (3); el elemento de conexión movible (3) permite la orientación del medio de filtrado (2) en la interfase entre el baño de electrodeposición catódica y el aire; y, después de la inmersión del palé (1) en el baño de electrodeposición catódica, durante el transporte del palé (1) a través del baño de electrodeposición catódica, el medio de filtrado (2) está orientado en la interfase entre el baño de electrodeposición catódica y el aire y es arrastrado a lo largo de la superficie del baño de electrodeposición catódica. Adicionalmente, la invención se relaciona con un palé para uso en el método de limpieza.
