Abstract
An apparatus and method for processing a sequence of webs by exposure to radiant energy. The apparatus includes structure defining a pair of independent transport paths and apparatus for emitting radiant energy and selectively directing it into either of two treatment zones, the respective treatment zones being aligned with the respective transport paths. The radiant energy is directed into the treatment zone aligned with each transport path while a web is being fed along such path. The leading end of each web is threaded along one of the transport paths while a web is being fed and treated on the other path, so the radiant energy emitting portion of the apparatus is not idle during threading.
