Abstract
1,221,695. Papermaking. BELOIT CORP. 22 May, 1968 [6 Nov., 1967], No. 24455/68. Heading D2A. An arrangement to transfer a paper web from a wire to a felt comprises an endless pickup felt, a guide member extending transversely of the felt for urging the felt into contact with the paper web, the guide member having a peripheral surface in the form of an arc of a cylinder, part of which is in contact with the felt, and a substantially flat surface extending in the opposite direction to the peripheral surface, and diverging away from the felt in the direction of travel of the felt at an angle of ¢-5for a sufficient length to create a substantial vacuum between the felt and the flat surface. The peripheral surface may have a radius of -10 inches, and the substantially flat surface may be slightly curved. The vacuum created by the flat surface may be varied by altering the radius of curvature of the surface, or by varying the angle it makes with the felt. A scraping device, preferably with a saveall may contact the felt immediately after the guide member. The scraper and guide member may form opposite ends of a wall defining a vacuum chamber. The member is shown, in embodiments, as picking a web from a Fourdrinier machine and from a cylinder machine.
