AI Technical Summary
The increase in conveying speed of absorbent articles leads to increased air resistance at the folded portions, causing shifts or wrinkles, resulting in shape variations during manufacturing.
A method and apparatus for manufacturing pant-type absorbent articles that involve folding the outer body in the width direction on both sides of the absorbent core, with specific folding steps and mechanisms to maintain the folded state, including folding one outer casing part at a point further outward than the absorbent core and then folding it again at a second point, and adjusting transport speeds to reduce air resistance.
This approach reduces shape variations and maintains a compact form of the absorbent article, enhancing stability and reducing leakage by ensuring the folded portions remain in place during transport and use.
