摘要： 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′″) disposed in predetermined positions along the length of the knife and the nose bar, whereby the heat transfer means (2, 2′, 2′″, 2″) placed in the stiffening rear portion (4″, 4′″; 5″, 5′″) of both the knife mounting beam (4) and the nose bar beam (5) are adapted controllable for adjusting the respective portions of the knife mounting beam and the nose bar beam under feedback from the second set of temperature sensors to a temperature value derived from the measurement signal given by the first set of temperature sensors.
