<p>A resaw has twin arbers with one to six blades mounted on each arber. In addition, the resaw has a rotatable fence with a continuous belt along its periphery. Two side pressure rollers are mounted adjacent to the rotatable fence between an entrance to the resaw and the blades. A workbed of the resaw is made up of a series of spiked rollers. Just prior to an exit from the resaw, there is located a top roller which is mounted normal to the side pressure rollers and can move further away from or closer to the workbed. The arbers are each powered by an electric motor. The rotatable fence, the side pressure rollers and the spiked rollers are all powered by hydraulic motors connected to a single power source and all rotate at the same speed at any given time. The side pressure rollers are automatically adjustable so that they exert pressure towards the rotatable fence on any wood that is located between said rollers and said fence. The side pressure-rollers, the rotatable fence and the spiked rollers operate together to force wood from an entrance to said resaw, past said arbers, to an exit. The resaw can be used to process lumber of various widths and heights without stopping the resaw to make adjustments as the lumber changes in size.</p> |
