  • Patent number: 5785102
    Abstract: Disclosed herein is an apparatus for positioning an elongate cant for the infeed of the cant into an edging device capable of longitudinally cutting the cant to remove the wane edges thereof. The apparatus generally comprises: a frame structure; a conveying module for transversely conveying the cant along a substantially straight path; a scanning module located along the path for optically scanning the morphology of the cant and providing morphology data; a computer module linked to the scanning means for analyzing the morphology data and calculating a longitudinal preferred infeed line for said cant; and a positioning means located further along the path for transversely positioning the cant to a colinear relationship with the preferred infeed line for said cant. More specifically, the positioning means comprises a plurality of spaced apart, releasable, pinching members.

  • Patent number: 5765617
    Abstract: An infeed system that orients a log for a processing unit. A flight conveyor, a log turner and a sharp chain are in an overlapping arraignment. The flight conveyor conveys a log past a scanner which inputs scan data into a computer which determines the profile and orientation on the flight conveyor. The computer determines the desired orientation of the log for the processing unit. The log turner is arranged to rotate and skew the log to the desired orientation. The log is then transferred to the sharp chain conveyor. The overlapping arrangement of the flight conveyor, log turner and sharp chain maintains full control of the log at all times. The sharp chain conveys the log past a second scanner which inputs the scan data to the computer to determine the actual orientation of the log on the sharp chain. The infeed system may also be provided with a shift and lift mechanism for further controlling the log position relative to the processing unit.
