ABSTRACT:
A carpenter planer in which a stock reciprocatingly moved on a stock feeder table by a stock feeding belt can be cut during both the forward movements and backward movements of the stock. On the stock feeder table, a knife stock is provided via rotary disc such that a planer blade can be turned round in accordance with the direction in which the stock is moved. When a stock is fed from a front portion of a planer base onto the upper surface of the stock feeder table, it is moved toward the rear portion of the planer base by a stock feeding belt. The stock is cut by a planer blade while it is moved in the above-mentioned manner. When the rear end of the stock comes off rearwardly from the upper surface of the rotary disc, the rotation of the stock feeding belt is interrupted as the stock is kept pressed on the stock feeder table by the stock feeding belt. The rotary disc is thereafter turned in the opposite direction and the planer blade is turned in a different direction. The stock feeding belt is then rotated in the backward direction. When the feeding belt is backwardly rotated, the stock is returned to the front portion of the planer base while being cut again by the planer blade. The stock thus cut again is discharged ahead of the front portion of the planer base through a space between the stock feeder table and the stock feeding belt. After the stock has been discharged, the rotary disc is turned again in the opposite direction to allow the planer blade to be turned in the opposite direction. The stock feeding belt is then forwardly rotated for the preparations of the following stock cutting operation.
