Abstract

157,982. Kõmpf, A., (Assignee of Koln- Rottweil Akt.-Ges.). Jan. 13, 1920, [Convention date]. No Patent granted (Sealing fee not paid). Pulping - machines. - Apparatus for reducing cellulose, alkali-cellulose, &c. to a loose and fine flocculent mass comprises a trough A and a rotary beater or beaters B provided respectively with teeth, grooves or channels a and teeth b, the grooves and teeth closely engaging one with the other and being arranged in such a manner that the material is subjected to a continuouscutting and pulverizing action as it is forced into and through the grooves; the number of cutting- edges is increased by interposing grooves a<1> in the length of the channels a. The beaters and grooves are arranged so that at least one tooth is in engagement; and the sides of the teeth may be inclined as shown, or parallel or curved.
