摘要:
A drying arrangement for strips or sheets of photosensitive material includes a pair of infrared heating rods which are located on opposite sides and extend transversely of the path of travel of the photosensitive material. A parabolic reflector is associated with each of the heating rods and serves to direct radiant energy from the same onto the photosensitive material. The heating rods lie at the focal points of the respective parabolic reflectors. Each of the reflectors has a symmetry plane which is inclined with reference to the path of the photosensitive material in such a manner that the line of intersection of the symmetry plane and the path is situated downstream of the location where a perpendicular from the focal point of the reflector to the path intersects the latter. By virtue of this arrangement, more radiant energy is directed to the upstream portion of the drying arrangement than to the downstream portion thereof. As a result, a thermal gradient exists in the drying arrangement. This gradient corresponds to the degree of dryness of the photosensitive material. Thus, the radiant energy is most intense in that portion of the drying arrangement where the photosensitive material carries the most liquid and least intense in that portion of the drying arrangement where the photosensitive material is virtually dry.
