Abstract

1287154 Papermaking BELOIT CORP 24 Nov 1969 [13 Feb 1969] 57398/69 Heading D2A In a twin-wire, vertical paper machine as shown, headbox 11 discharges stock between breast rolls 13, 14 and into the area between wires F 1 , F 2 . In the forming zone arcuate surfaces such as rolls 15 or part-cylindrical surfaces, arranged alternately, and spaced downwardly change the direction of travel of the wire first one way then the other. The change must be greater than 5‹. The web may then be further dewatered by suction box 16, and couched onto pickup felt PF by roll 19 with suction gland 19a. Rolls 13b and 14b may be driven as shown at M 1 and M 2 . Savealls S are provided, and doctors 13a, 13b', 14a, 14b', 15a may be provided to clean the rolls. The arcuate surfaces may be rolls as shown, and the rolls may have a mirror-like finish ceramic coating, and be solid rolls. The rolls need not rotate, but may be stationary.
