Abstract
The subject-matter of this Specification is substantially the same as that described in Specification 929,492 but the claims are concerned with a method of separating wood fibres from a log by simultaneously subjecting the surface of the log to fluid loosening and grinding actions and comprising the steps of directing the action of a grinding wheel against the log surface to pull the fibres lengthwise from the log in a direction generally parallel to the longitudinal axis of the log, and directing the fluid loosening action against the surface layer of fibres on the log to loosen them prior to the grinding wheel action thereagainst. An acidic or alkaline solution may be used. Specification 845,497 also is referred to.
