Abstract:
A veneer lathe knife assembly supported by a frame assembly, comprising:a knife mounting beam and a nose bar beam, both of which having a front portion which hold a cutting knife and a nose bar, respectively, and a stiffening rear portion, said knife mounting beam and said nose bar beam being movable relative to each other on the frame assembly, wherein adjustment of the knife gap formed between the cutting knife and the nose bar is accomplished by the relative movement between said knife mounting beam and said nose bar beam; heat transfer means arranged in to the stiffening rear portion of both the knife mounting beam and the nose bar, wherein both the knife mounting beam and the nose bar beam have placed thereon, in a close vicinity to the cutting knife and the nose bar, at least one first set of temperature sensors disposed in first predetermined positions along a length of the cutting knife and the nose bar, wherein both the knife mounting beam and the nose bar beam have placed thereon, at a distance from the knife and nose bar, at least one second set of tempeature sensors disposed in second predeted positions along the length of the cutting knife and the nose bar, wherein the heat tansfer means include temperature adjusting means for adjusting a temperature of respective portions of the knife mounting beam and the nose bar beam, using feedback from the at least one second set of temperature sensors, to a temperature value derived from a measurement signal provided by the at least one first set of temperature sensors.
