ABSTRACT:
A method and apparatus for curing a photosensitive coating on a moving substrate.
A method for curing a photosensitive coating on a moving substrate by exposing the coating to a beam of light emitted from a high intensity light source. The substrate is substantially shielded from direct rays of light from such light source and the beam of light is reflected and focused in a broadening path, initially generally parallel to and spaced from the substrate, filtered and caused to strike a reflective surface that subsequently reflects and redirects the broadening beam of light to impinge in a band upon the photosensitive coating to cure it as it passes on the moving substrate.
Apparatus for curing a photosensitive coating on a moving substrate comprising a high intensity light source, which is substantially shielded to prevent its direct rays from striking the photosensitive coating; a first reflector, which partially surrounds the light source to focus a portion of the light therefrom in a broadening beam generally parallel to the moving substrate; a transaprent coolant-filter, which is located on the opposite side of the light source from the first reflector, for filtering the broadening beam from the light source; a second reflector, which is on the opposite side of the filter from the light source, to receive the focused and filtered broadening light beam and redirect it at an angle to impinge in a band on the photosensitive coating to cure it as it passes beneath the apparatus on the moving substrate.
