Title:

METHOD FOR MANUFACTURING COMPOSITE FOR CONTINUOUS SHEET USED IN ABSORBENT ARTICLES, MANUFACTURING APPARATUS, AND METHOD FOR MANUFACTURING ABSORBENT ARTICLE

Document Type and Number:

WIPO Patent Application WO/2012/029572

Kind Code:

A1

Abstract:

A method in which a composite for a continuous sheet used in absorbent articles is manufactured by pasting a cut sheet to a continuous sheet at a predetermined pasting pitch. The method has the steps of: holding the cut sheet in a state of surface contact in a holding unit that travels along a circular path; and separating the cut sheet from the holding unit when the holding unit moves past a handover position established on the circular path, and pasting and handing over the cut sheet to the continuous sheet travelling through a position in the vicinity of the handover position. In the handover step, the holding force for holding the cut sheet is reduced and the suction force for suctioning the cut sheet toward the continuous sheet is applied through the continuous sheet, whereby the cut sheet is pasted to the continuous sheet without being pinched between the holding unit and the continuous sheet.
