ABSTRACT:
A cross-direction web dryer includes a support structure arranged transversely across the moving web consisting of a pair of elongated support members each carrying side-by-side heater modules facing the moving web. This pair of structural members may be moved from the above operating position by a rotating and pivoting action to a stowed position where the heater elements are juxtaposed and co-extensive with one another to effectively thermally capture the heat of the heater elements. This reduces the heating up of the surrounding area while the heater elements cool down and prevents paper scrap and other flammable products from igniting that could create a fire hazard.
