Manufacturing method and manufacturing apparatus for disposable wearable article

A method for manufacturing a disposable wearable article in which an absorbing body overlaps an external material, the method comprising:

• an introduction step of introducing a continuous laminated body, which extends in a carrying direction, to an anvil roll at an introduction velocity, the continuous laminated body being to be used as absorbing bodies;
• a slip step of carrying the continuous laminated body at the introduction velocity, the slip step being performed by sucking a tip end of the continuous laminated body on a peripheral surface of the anvil roll rotating at a drum velocity higher than the introduction velocity, with the tip end of the continuous laminated body slipping over the peripheral surface of the anvil roll;
• a cutting step of intermittently cutting the tip end of the continuous laminated body on the anvil roll to thereby sequentially obtain the absorbing bodies;
• a separation step of carrying the absorbing bodies, which have been cut in the cutting step, at the drum velocity along the peripheral surface of the anvil roll to thereby separate the absorbing bodies from the continuous laminated body in the carrying direction;
• a first transfer step of sequentially transferring the absorbing bodies, which have been separated in the separation step, from the anvil roll to respective retention pads P of a turn drum;
• a posture change step of allowing the retention pads of the turn drum to rotate around an axis line of the turn drum at a fixed velocity that equals the drum velocity, the posture change step allowing each of the retention pads on the turn drum to turn around a normal line of the turn drum to thereby change a posture of the absorbing bodies together with the retention pads;
• a second transfer step of transferring the absorbing bodies from the retention pads of the turn drum to respective velocity-changeable pads and of a velocity-changeable roller at a receiving position at the drum velocity;
• a velocity change step of changing a velocity of the velocity-changeable roller from the drum velocity to an arrangement velocity until the velocity-changeable roller reaches a delivery position from the receiving position;
• a carrying step of allowing a carrying device to carry an external material at the arrangement velocity;
• and
• an arrangement step of sequentially arranging, at the delivery position, the absorbing bodies over the exterior material carried by the carrying device.
