A chuck head is arranged below the roll loaded on a loading shaft. The chuck head is supported by a parallel link mechanism to be movable while keeping its horizontal position. The chuck head is moved upward to peel the leading end portion of the strip-like material from the peripheral surface of the roll. The strip-like material is unrolled by base and pinch feed rollers. A predetermined portion of the leading end portion of the drawn strip-like material is cut by a cutter unit. The cut unnecessary portion of the leading end portion of the strip-like material is exhausted.
