ABSTRACT:
A device for continuously feeding logs into a machine center to cut or chip pieces from the sides thereof is disclosed. The device includes opposed upper and lower tracks mounting upper and lower endless drive chains. Each drive chain mounts a plurality of spaced dogs adapted to be disposed in alternating sequence of upper and lower pairs, each dog having a horizontally directed gripping surface whereby a log may be gripped between a pair of upper and lower dogs and fed through a machine cutting center. As a first log held by a pair of upper and lower dogs passes through the machine, a second pair on each chain rotates into a feeding position for gripping a second log to be taken through the machine. The device also includes associated centering and positioning members to align logs entering the machine, conveyors for cut pieces, and means for interlocking the upper dog in the lower track as the log gripped thereby passes through the machine center.
