Abstract:

An infeed conveyor feeds logs lengthwise toward a sawing, chipping or other log processing machine. The infeed conveyor has two endless conveyor chains which circulate in an infeed conveyor path carrying flights along low-friction guides. To assist in obtaining optimum lumber recovery from logs, each flight has a load-engaging portion for cradling logs which is movable transversely of the infeed path so that a tapered log is laterally and angularly positioned as desired with respect to the centerline of the moving conveyor. Line bars along the conveyor, moved by manually or automatically-actuated cylinders engage the load-engaging portion of the flights to shift them and a supported log laterally to a desired alignment. The load-engaging portion of each flight is held in an adjusted lateral position after the line bars retract by friction blocks compressed between the load-engaging portion and the base portion. The load-engaging portion has low-friction bearing pads which slidingly support it on stationary support surfaces of the conveyor frame as a log is conveyed.
