Abstract

396,063. Sizing and filling paper pulp webs. MEAD CORPORATION, City National Bank Building, Dayton, Ohio, U.S.A.-(Assignees of Bair, W. E. ; 318, McKellar Street, Chillicothe, Ohio, U.S.A.) March 4, 1932, No. 6551. Convention date, March 9, 1931. [Class 96.] Material, e.g. a suspension of filler, size, &c. of a nature to compensate for that which is withdrawn by drainage through the wire-cloth, is supplied to the wire side of a paper pulp web after an initial web formation has been effected, thus giving both sides of the finished paper a similar appearance even if large quantities of filler are used. A roller 20, which may be the wire guide roller of a Fourdrinier paper-making machine and which may be covered with hard rubber and is positioned subsequently to the dandy roller 16 and suction boxes 17 is supplied with filler &c. from a trough 30 having a supply pipe 31 and an overflow pipe 32. The filler may be supplied through a slotted pipe positioned to raise the wire so as to cover the slot completely. The web may have 10 to 30 per cent of solid matter when the additional filler is supplied, such filler may comprise 22 lbs. of carbonate and 3¢ lbs. of size in 40 galls. of water.
