Abstract

The present invention provides a method for continuously manufacturing a stretchable sheet () with a thread-shaped elastic body () fixed between a pair of belt-shaped sheets () in a stretched state, the method including a supply process of introducing the fed thread-shaped elastic body () to elastic body winding means () in a stretched state, a conveyance process of continuously winding the thread-shaped elastic body () to a thread-conveying longitudinal structure () using the elastic body winding means () and conveying the wound thread-shaped elastic body in a longitudinal direction of the structure (), and an integration process of fixing the thread-shaped elastic body () as sandwiching between the sheets (). In the supply process, the thread-shaped elastic body () is introduced to the elastic body winding means () while adjusting a speed of the thread-shaped elastic body () to be equal to or higher than a winding speed against the pair of conveying belts () with speed adjusting means (B) which is arranged at the upstream side of the elastic body winding means ().
