Abstract
In the present invention, one surface of a belt-shaped sheet laminate (10), in which a plurality of sheets are laminated, is pressed against a support member (21) having a light passage section (27) through which a laser beam (30) can pass, and the belt-shaped sheet laminate (10) is irradiated, from the support member (21) side via the light passage section (27), with a laser beam (30) to cut and fusion-bond the belt-shaped sheet laminate (10), thereby sealed edge sections (4) are formed by fusion-bonding the edge sections of the plurality of sheets.
Claims4
A method for manufacturing an absorbent article comprising a fusion-bonded sheet article and an absorbent assembly, the method comprising the steps of:
- providing a belt-shaped sheet laminate comprising a plurality of sheets, at least one sheet of the plurality of sheets including a resin material;
- pressing one surface of the belt-shaped sheet laminate against a support member that has a light passage section through which a laser beam can pass;
- irradiating, from a support member side via the light passage section, the belt-shaped sheet laminate which is in a pressurized state with the laser beam having a wavelength that is absorbed by the sheets constituting the sheet laminate and that causes the sheets to generate heat;
- and
- cutting and separating the belt-shaped sheet laminate and, simultaneously, fusion-bonding cut edge sections created, by a cutting/separation, in the plurality of sheets which are in the pressurized state to form sealed edge sections, so that the fusion-bonded sheet article is obtained.
