Veneer peeling knife and a method of fixing a knife adjusting bolt of said veneer peeling knife

摘要

A method of fixing an adjusting bolt of a veneer peeling knife which is usually performed after adjusting the knife in a knife setting gauge to position its cutting edge at a desired height. The adjusting bolt is fixed by forcing the adjusting bolt by a fixing member in such a direction that the advancing side flank of the external thread of the adjusting bolt is kept in pressed contact with the lower side flank of the internal thread of a threaded hole formed in the knife bottom and receiving therein the adjusting bolt by thread engagement. The fixing member may be provided by a rigid member disposed below the knife bottom surface and formed with a threaded hole through which the adjusting bolt is inserted by thread engagement so that forcing the fixing member upward by a pressing member such as a bolt in a direction that effects the pressed contact between the above two flanks fixes the adjusting bolt securely to place. The fixing member is provided by any suitable resilient material such as silicon rubber. Causing the resilient fixing member to be deformed so as to urge the adjusting bolt in a direction perpendicular to the axis thereof, the above flanks are pressed in tight contact with each other by the wedging action thereby to fix the adjusting bolt. A veneer peeling knife itself can be equipped with a device for fixing the knife adjusting bolt.
