Abstract

268,180. Dehn, F. B., (Beloit Iron Works). May 31, 1926. Fourdrinier paper machines. - In Fourdrinier paper machines wherein the table structure is removable for changing the wire cloth, the couch roll 24 is mounted on an extension 22, Fig. 1, of the table 1 and is movable therewith. The suction pipe has a removable section 26 to facilitate dismantling prior to moving the table structure. In a modified construction, the couch roll is mounted in separate pedestals 33, Fig. 3, and, for changing the wire, a removable bridge beam 44 is inserted and the couch roll is run over the beam on to the extension 45 of the table. A rack 47 is provided on the beam for this purpose and gear teeth 36 engage therewith, the roll being turned by a handle on a stub shaft 43. The couch roll bearings 34 are mounted in brackets 35 having removable lug members 39 provided with teeth 40 for engaging between two adjacent teeth 36. In another arrangement, extensions of the table may have pockets into which the couch roll may be lifted from its separate pedestal bearings.
