Abstract
872,068. Web-formation in paper-making machines. BELOIT IRON WORKS. Sept. 27, 1957, No. 30395/57. Class 96. Paper pulp supplied from a flow-box 15 to the wire-cloth 10 above an open breast roll 11 of a Fourdrinier paper-making machine is subjected to suction through the roll 11 and wire 10, the roll 11 being partly surrounded by a suction save-all enclosure 18; the wire 10, at its entry into the enclosure passing through an adjustable gap G which acts as a partial vacuum seal. The wire 10 leaving the roll 11 passes between side seals 23 and above an adjustable deflector 21 for removing water from beneath the wire-cloth, a further deflector 27 being provided adjacent a table roll 12. In modifications, the gap G may have corrugated surfaces on each side; or the gap may be on one side of a wire-guide roll adjoining which is a doctor with a sealing tube; or the gap G may be formed as a water seal. In other modifications, there is a succession of suction zones with table rolls 12 and deflectors 27 extending along the underside of the wirecloth. The table roll 12 may be solid, dandy type, or grooved. Specification 871,247 is referred to.
