Abstract

390,318. Rasping wood. HEYMANN, P. H. 39, Emserstrasse, Wilmersdorf, DIESING, K. E., 88, Bismarckstrasse, and ROTHGIESSER, H., 10, Stuhm Allee, both in Charlottenburg, both in Berlin. March 21, 1932, No. 8388. Convention date, March 26, 1931. [Class 59.] Pre-dried wood, preferably hard wood, is cut tranversely to the grain on the end face thereof by means of circular-saw blades and the granular disintegrated wood obtained is cleaned from the coarse or fibrous particles in a subsequent sifter, the coarse or fibrous particles being subjected to a subsequent grinding process. As shown in the Figure, the preferably hard wood 1 is cut across the end of the grain by saw-like teeth 21 on discs 4 mounted on a rotating shaft 3, the disintegrated wood being drawn by a fan 6 into a sifter 8. The fine material is discharged through a pipe 9, and the coarse material passes through a pipe 10 into a rotary drum 11 containing stones 12, the fine material i rom the drum being drawn off by a fan 14 into a collector 15. The teeth 21 may be arranged in parallel rows or alternate rows are displaced so that a tooth in one row comes opposite a gap in the other. The discs 4 may be provided with projections or recesses which engage straight or helical grooves or keys on the shaft 3.
