FIELD: manufacturing technology.

SUBSTANCE: stretchable elastic elements (15–19) are arranged between first sheet material (12S) and second sheet material (12H), and overlapping areas of first sheet material (12S) and second sheet material (12H) are not connected to each other in both end parts in a transverse direction, but are connected to each other in the area between both end parts, as a result, ribbon-like continuous elastic belt (12) is formed. Elastic belt (12) is cut at its mid point in the transverse direction between the stretchable elastic elements (15–19) in the connection position of the first sheet material (12S) and the second sheet material (12H), and paired separated elastic belts (12f and 12b) are formed. Positions of transverse direction of these separated elastic belts (12f and 12b) are reverse or separated elastic belts (12f and 12b) are opposite in vertical direction. Front side of outer housing (12F) and rear side of outer housing (12B) are formed from paired separated elastic belts (12f and 12b).

EFFECT: invention discloses a method for production of a disposable diaper in the form of underwear and a disposable diaper in the form of underwear.
