Abstract
An apparatus for surfacing a flitch by cutting material from its radially outer surface to prepare the flitch for veneer slicing or other uses. The apparatus comprises a cutterhead rotatable about a cutterhead axis. The apparatus further comprises a carriage comprising a ring that rotates about a carriage axis and a pivot arm that carries the cutterhead and is coupled to the rotatable ring for pivoting movement about a pivot arm axis. The apparatus further comprises a flitch contour accommodation device coupled to the pivot arm and to the cutterhead to permit rotation of the cutterhead about a device axis that is generally transverse to the cutterhead axis.
Claims21
An apparatus for surfacing a flitch by cutting material from its radially outer surface to prepare the flitch, the apparatus comprising:
- a cutterhead rotatable about a cutterhead axis,
- a carriage comprising a ring rotatable about a carriage axis and a pivot arm carrying the cutterhead and coupled to the rotatable ring for pivoting movement about a pivot arm axis, and
- a flitch contour accommodation device coupled to the pivot arm and coupled to the cutterhead to permit rotation of the cutterhead about a device axis that is generally transverse to the cutterhead axis.
An apparatus for surfacing a flitch by cutting material from its radially outer surface to prepare the flitch, the apparatus comprising:
- a cutterhead rotatable about a cutterhead axis,
- a carriage comprising a ring rotatable about a carriage axis and a pivot arm carrying the cutterhead and coupled to the rotatable ring for pivoting movement about a pivot arm axis, and
- a carriage oscillator to oscillate the carriage back and forth about the carriage axis as the flitch passes the cutterhead to cut material from a radially outer surface of the flitch.
An apparatus for surfacing a flitch by cutting material from its radially outer surface to prepare the flitch for veneer slicing or other uses, the apparatus comprising:
- a cutterhead rotatable about a cutterhead axis,
- a carriage comprising a ring rotatable about a carriage axis and a pivot arm carrying the cutterhead and coupled to the rotatable ring for pivoting movement about a pivot arm axis, wherein the cutterhead axis is configured to traverse the flitch.
