BASE PAPER SUPPLYING METHOD FOR CORRUGATE MACHINE

PROBLEM TO BE SOLVED: To provide a base paper supplying method capable of shortening the cycle time for changing a roll. SOLUTION: A first arm mechanism 28 provided with first arms 13, a second arm mechanism 29 provided with second arms 13, a roll carrying-out conveyor EX between both mechanisms, a first roll carrying-in conveyor IN1 outside from the first mechanism, a second roll carrying-in conveyor IN2 outside from the second mechanism are provided. A first roll 14 carried in by the first conveyor is chucked by the first arms 13, a second roll 14 carried in by the second conveyor is chucked by the second arms 13, the arms 13 are oscillated upward from the carrying-out conveyor, and the first roll 14 is used. The second roll 14 chucked by the second arms 13 wait a next use at the position above the second conveyor, the first roll 14 is carried out by the carrying-out conveyor by releasing the first arms 13 when the order of the first roll 14 is completed, the second arms 13 are oscillated upward from the carrying-out conveyor, and the second roll 14 chucked by the arms is used.
