A veneer lathe for the peeling of a continuous strip of veneer off a log is arranged to automatically adjust the peeling blade angle and the position of the pressure roll as the log being peeled decreases in diameter. A control, such as a computer, is provided to control motors that adjust the angle of the blade and the position of the pressure roll according to the instant diameter of the log being peeled and in conjunction with other data input to the computer. A holder which supports the peeling blade is pivotally mounted on a movable carriage of the lathe. Pivoting the holder adjusts the angle of the blade. A carrier, which has a movable slide on which the pressure roll is mounted, is also pivotally mounted on the carriage. Pivoting the carrier will adjust the pressure roll vertically in relation to the peeling blade and movement of the carrier slide will adjust the pressure roll laterally in relation to the peeling blade. Position sensors are provided on the carriage, the blade holder, the carrier and the carrier slide to provide position feedback signals to the control.
