Abstract: The present invention provides a method for continuously manufacturing a stretchable sheet (3) with a thread-shaped elastic body (7) fixed between a pair of belt-shaped sheets (50, 60) in a stretched state, the method including a supply process of introducing the fed thread-shaped elastic body (7) to elastic body winding means (14) in a stretched state, a conveyance process of continuously winding the thread-shaped elastic body (7) to a thread-conveying longitudinal structure (12, 13) using the elastic body winding means (14) and conveying the wound thread-shaped elastic body in a longitudinal direction of the structure (12, 14), and an integration process of fixing the thread-shaped elastic body (7) as sandwiching between the sheets (50, 60).

Abstract: A transportation path changing device (1) of the invention is a transportation path changing device that changes a transportation path of a continuous sheet-like object (3) that is being transported. The device includes: an oscillating section (2) that oscillates in an intersecting direction Y intersecting with a flow direction X of the transported object, and that increases/decreases the length of the transportation path of the transported object (3); a first moving means (6) that is connected to the oscillating section (2), and that moves the oscillating section (2) in the intersecting direction Y; a second moving means (7) that moves a portion or the entirety of the first moving means (6) in the intersecting direction Y; and a control section (9) that controls the first moving means (6) and the second moving means (7).

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.

Abstract: One surface of a belt-shaped sheet laminate (10) (continuous diaper strip), in which a plurality of sheets are laminated, is made to abut 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) which is in a pressurized state is irradiated, from the support member (21) side via the light passage section (27), with a laser beam (30) having a wavelength that is absorbed by the sheets constituting the sheet laminate (10) and that causes the sheets to generate heat, and thus, the belt-shaped sheet laminate (10) is cut and separated and, simultaneously, cut edge sections created, by the cutting/separation, in the plurality of sheets which are in the pressurized state are fusion-bonded together. Thus, sealed edge sections (4) (side seal sections) are formed by fusion-bonding the edge sections of the plurality of sheets in a state where the sheets' edge sections are superposed.
