ABSTRACT:
A workpiece conveying and feeding unit for conveying a long workpiece in the lengthwise direction to feed the workpiece to a cutting machine is disposed in the rear of the cutting machine. A workpiece conveying unit conveys the workpiece in the lengthwise direction of the workpiece into a workpiece conveying passage of the workpiece conveying and feeding unit. When a plurality of workpieces placed on the workpiece conveying unit are sequentially conveyed to the workpiece conveying passage of the workpiece conveying and feeding unit to convey the workpieces to the cutting machine, the side surface of the workpiece which is conveyed to the workpiece conveying passage of the workpiece conveying and feeding unit by the workpiece conveying unit is detected by a side-surface detector. In accordance with the conveyance distance calculated in accordance with the diameter of the workpiece, the side surface of which has been detected, and the positional relationship between the workpiece conveying passage and the side-surface detector, the workpiece is located on the workpiece conveying passage.
