ABSTRACT:
The present invention relates to method making an incontinence diaper built up from a barrier layer (1) and a nonwoven layer (2) affixed thereto for providing two portions (6, 7) surrounding the lower part of the body and a crotch portion (8) connecting these portions. At least one elastic band (17, 18) extends from the central part of the crotch portion (8) along both side edges (11, 12) of said portion, in over both portions (6, 7) and along the entire length of the diaper with the elastic band (17, 18) being attached with a continuously varying tension in the diaper material. The tension in the elastic band (17, 18) is greatest at the crotch portion (8) and dimishes to approximately half its value over both the portions (6, 7).
