ABSTRACT:
A woodworking planer having a main frame, a carriage slidingly mounted on the main frame to provide alternating longitudinal movement, a workpiece locking device also provided on the main frame for releasingly securing a workpiece in a fixed position relative to the longitudinal movement of the carriage, and cutting members provided on the carriage to plane four longitudinal sides of the workpiece simultaneously. The cutting members include horizontal cutter heads simultaneously moveable vertically towards and away from each other, and vertical cutter heads individually moveable horizontally towards and away from each other in response to predetermined shapes of a copying model co-acting with copying parts connected to the vertical cutter heads. The copying parts include spring biased rollers for following the predetermined shapes of the copying model. A feeder arrangement receives the workpieces for individually feeding the workpieces one at a time to the workpiece locking device. An inclined ramp receives the finished workpiece from the workpiece locking device, and directs the finished workpiece to a conveyor belt so that the finished workpiece can be transported away from the woodworking planer.
