<p>For supporting a web of material in a contact-free manner and also for drying the material, a U-shaped box-like member is arranged so that its open side faces toward the surface of the web to be supported. An air baffle plate is positioned in the open side of the box-like member and has a curvilinear shape along each of its edges located closely adjacent to the opposite closed sides of the box-like member. The spacing between the opposite sides and the curvilinear surfaces of the air baffle provide openings through which air is directed so that it follows the curvilinear surface of the air baffle and provides a cushion between the air baffle and the web. The air baffle can be formed in various ways, for example, by a pair of spaced tubular members joined by a plate member, by an oval shaped member and by a plate member with curved edges joined by a flat or undulating section.</p> |
