Abstract
800,801. Fourdrinier paper-making machines. DORRIES A.G., O. May 9, 1956 [May 9, 1955], No. 14422/56. Class 96. An upper framework 1 of an entire Fourdrinier paper-making machine suitable for high speed production of thin paper or creped cellulose wadding &c. is supported by beams 2, 3 and 4; the beam 4 may be under tension to reduce sagging of the framework 1 under the weight of a Yankee drier-drum 24, and the beams 3 may support a calender press 9. The design of the framework 1 &c. allows transfer of the web between the various sections with minimum draw, and facilitates wire-changing which is effected laterally with the aid of a carriage. A central housing 11 supports rollers 13, 14, &c., and accommodates pneumatic or oil cylinders &c. for the upper couch roll 14 or upper wet press roll. The framework 1 may have tracks for a mobile crane.
