Abstract
In a peripheral exhaust system for a high velocity dryer having dryer hood sections and respective supply and removal ducts associated with each section through which recirculating air used for drying is carried to and away from the sections, auxiliary exhaust ducts formed along the periphery of the sections adapted to receive a portion of the hot air used for drying that would otherwise enter the area surrounding the dryer hood and a portion of the cold air from the surrounding area that would otherwise enter the dryer hood. The exhaust ducts are connected by blowers to ducts which remove the air to a location remote from the web.
