Method for production of diaper pants

Abstract

A method of production of disposable diaper pants or disposable sanitary panty with openable and resealable side panels. A row of absorption bodies is applied on a continuous web of inner or outer cover sheet material, after which a continuous web of outer or inner cover sheet material is applied and secured to the web with absorption bodies at parts lying outside the absorption bodies to form a web of diaper pants blanks. First side panels having two parts connected by a detachable and resealable connection are secured to the diaper pants blanks at a side of a front or rear portion. Second separate side panels are secured to the side portions of the front or rear portions of the diaper pants blanks which to not have side panels. Individual diaper pants blanks with side panels are cut out, folded along a transverse axis in the crotch, and secured.
