PROBLEM TO BE SOLVED: To suppress a positional deviation in a width direction of a composite sheet, in which a stretchable sheet is jointed to a width direction end portion of a continuous sheet.SOLUTION: An elastic member manufacturing method characterized: in that, to the end portion of the widthwise direction or the direction to intersect the continuing direction of a continuous sheet, there is jointed a continuum of a stretchable sheet in a state continued in said continuous direction and extended in said widthwise direction, thereby to form a continuum of a composite sheet and in that, after the continuum of said composite sheet was formed, when the continuum of said composite sheet is conveyed along said continuous direction while the position of said width direction of said continuous sheet being constricted, the continuum of said stretchable sheet is shrunken in said widthwise direction, and a fastening tape is jointed to said continuous sheet.COPYRIGHT: (C)2014,JPO&INPIT【課題】連続シートの幅方向の端部に伸縮性シートが接合された複合シートの幅方向の位置ずれを抑制すること。【解決手段】連続シートの連続方向と交差する方向である幅方向の端部に、前記連続方向に連続し前記幅方向に伸長した状態である伸縮性シートの連続体を接合して、複合シートの連続体を形成することと、前記複合シートの連続体の形成後、前記連続シートの前記幅方向の位置を拘束した状態で前記複合シートの連続体を前記連続方向に沿って搬送する際に前記伸縮性シートの連続体を前記幅方向に収縮させた後に、止着テープを前記連続シートに接合することと、を有することを特徴とする伸縮性部材の製造方法である。【選択図】図5
