Cutting blade holding device in veneer lathe

A cutting blade holding device in a veneer lathe which peels off a veneer with a cutting blade caused to abut on a peripheral surface of a log chucked by spindles to rotate in a predetermined direction, said cutting blade holding device comprising:

• a blade stock supported movably relative to a body frame in a veneer traveling direction perpendicular to an axis of the spindles, and having its upper side in terms of the veneer traveling direction formed with a cutting blade retaining portion having notches,
• a backing plate mounted on the upper side of the blade stock in terms of the veneer traveling direction with the top of its upper side in terms of the veneer traveling direction located adjacently to a cutting edge of the cutting blade, and having its upper surface formed into a first guide surface extending from the upper course toward the lower course in its section along the veneer traveling direction,
• an abutment member mounted on the blade retaining portion of the blade stock located on the lower side of the backing plate in terms of the veneer traveling direction, and having its upper side in terms of the veneer traveling direction formed with an engagement portion for engaging with the upper notch, and having its upper surface formed into a second guide surface whose upper end in terms of veneer traveling direction is substantially continuous with the lower end of the first guide surface of the backing plate in terms of the veneer traveling direction and which extends from the upper course toward the lower course in its section along the veneer traveling direction, and
• blade presser members supported on the upper side of the blade stock in terms of the veneer traveling direction for oscillation, which press the cutting blade supported on the upper end of the backing plate in terms of the veneer traveling direction to secure the cutting blade.

• an abutment member mounted on the blade retaining portion of the blade stock located on the lower side of the backing plate in terms of the veneer traveling direction, and having its upper side in terms of the veneer traveling direction formed with an engagement portion for engaging with both the upper notch of the cutting blade retaining portion and the engagement portion of the backing plate, and having its upper surface formed into a fourth guide surface whose upper end in terms of veneer traveling direction is substantially continuous with the lower end of the third guide surface of the backing plate in terms of the veneer traveling direction and which extends from the upper course toward the lower course in its section along the veneer traveling direction, and
• blade presser members supported on the upper side of the blade stock in terms of the veneer traveling direction for oscillation, which press the cutting blade supported on the upper end of the backing plate in terms of the veneer traveling direction to secure the cutting blade.
