PROBLEM TO BE SOLVED: To provide a manufacturing method of a stretchable sheet by which a stretchable sheet with high stretchability in a plurality of directions can be continuously and efficiently manufactured with simple facilities.SOLUTION: The manufacturing method of stretchable sheet includes a step in which, after a string shape elastic body 7 is wound around a pair of string conveying structures 12, 13 separate in a direction orthogonally crossing a direction of conveying the sheet using an elastic body winding means 14 and is conveyed, the pair of string conveying structures 12, 13 are put and fixed in between band shape sheets 50, 60. Each of the pair of string conveying structures 12, 13 includes longitudinal members 12a, 13a in an upper step and longitudinal members 12b, 13b in a lower step. In one string conveying structure 12 and the other string conveying structure 13, feeding speeds V1a, V2a of the string shape elastic bodies by the longitudinal members in the upper step and feeding speeds V1b, V2b of the string shape elastic bodies are controlled to be changed to manufacture the stretchable sheet 3A etc. in which the plurality of string shape elastic bodies are arranged oblique to a direction orthogonally crossing the conveying direction of the sheet and in parallel. |
