Abstract
The invention relates to a veneer lathe knife assembly comprising supported by a frame assembly a knife mounting beam (4) and a nose bar beam (5), both of which having a front portion (4′; 5′) for holding a cutting knife (6) and a nose bar (7), respectively, and a stiffening rear portion. The knife mounting beam (4) and the nose bar beam (5) are adapted movable relative to each other on the frame assembly so as to permit adjustment of the knife gap formed between the cutting knife (6) and the nose bar (7). Heat transfer means (2, 2′, 2″, 2′″) are adapted to the stiffening rear portion of both the knife mounting beam (4) and the nose bar beam (5). Both the knife mounting beam (4) and the nose bar beam (5) have placed thereon, in a close vicinity to the knife (6) and the nose bar (7), at least one first set of temperature sensors (3, 3′) disposed in predetermined positions along the length of the knife and the nose bar. Furthermore, both the knife mounting beam (4) and the nose bar beam (5) have placed thereon, at a distance from the knife (6) and the nose bar (7), at least one second set of temperature sensors (1, 1′, 1″, 1′…
