Abstract

1426248 Drying web-like material ESCHER WYSS GmbH 14 March 1973 [14 March 1972] 12294/73 Heading F4G A drying apparatus comprises two rows of cylinders 2 through which apparatus material 3 e.g. paper in order to be dried travels alternately from row to row wrapping around each cylinder in turn as it passes. Each cylinder is associated with and wrapped by a web which is in contact with the material 3 different webs 4, 5 being associated with adjacent cylinders, the webs associated with adjacent cylinders extending on both sides of the material where the material 3 is not wrapped around a cylinder. As shown in Fig. 1, the perforated cylinders 1, 2 are enclosed by an air supply hood 8 in the region wrapped by the belts 5, 4 and the interiors thereof are connected to an air suction device which produces a vacuum in the cylinders. Undesirable flow losses are prevented by covers 9, and infra-red microwave driers are disposed within the hoods 8. In modifications, (a) a steam-heated cylinder (10) Fig. 2 (not shown) is arranged in the region where the material 3 is about to wrap around a given cylinder and where the material has just left the cylinder, the air supply hoods being provided with air supply ducts (12) and air discharge ducts (13), and (b) a single perforated belt is used for each row of internally heated solid-wall cylinders, Fig. 3 (not shown).
