    摘要： A sawmill apparatus includes first and second carriages for supporting first and second logging dogs therebeneath, with the second carriage being movable upon the first whereby to engage the ends of a log between the dogs. The carriages support the dogs at the end of steel blades which are moved in a vertical direction by a combination of air cylinders and ball screws to provide accurate positioning of the log at a predetermined distance above a lower saw guide and at a predetermined distance above an outfeed conveyor. Side braces are mounted on each carriage and extend downwardly on each side of the blades carrying the log engaging dogs, the side braces supporting bearing members disposed in slidable relation to the blades for maintaining alignment thereof in the direction of carriage movement.

    摘要： Sawmill methods are provided including automatic log turning methods in combination with improved non-defacing gripping techniques. A pair of gripping arms engage a log on a headblock at oppositely located points adjacent the vertical portion of the headblock so as to be offset with respect to the center of a log. After a first saw cut, the upper gripping arm is removed and the lower gripping arm is raised to rotate the saw log. In a further aspect of the method, a projecting bumper is provided in the vertical portion of the headblock between the log and the upper released gripping arm to assist in turning the log.
