Shape sawing system

摘要

This invention applies to a shape sawing system for sawing lumber pieces from a curved cant portion. A scanner scans the cant portion as it is conveyed on a conveyor system and inputs the scan data into a computer. The computer determines the curvature and position of the cant portion on the conveyor system. The conveyor system conveys the cant portion through side chippers and into a saw. The side chippers are independently laterally adjustable to follow the curvature of the cant portion. Guide members mounted strategic to the saw guide the cant portion into the saw. The saw is pivotally and laterally adjustable to follow the curvature of the cant portion to produce full length and partial length lumber pieces from the cant portion.
