ABSTRACT:
An apparatus (10) having a rotating fiberizing disc (26, 226 or 326) for fiberizing wood blocks (100) to produce fibrous elements is described. The apparatus includes a housing (12) within which is mounted the disc. The disc is provided with a series of rows (32, 232 or 332) of teeth (28, 228 or 328) on the front planar face (26A, 226A or 326A) as well as a scraper (30, 230 or 330). The wood block is advanced to the face of the disc in a manner such that its long grain direction can be controlled at various angles with respect to the path of the circularly travelling teeth and thereby changing the nature of the resulting fibrous elements.
