Abstract
A method for production of disposable hygienic absorbent articles () in which each article has a substantially homogenous elastic laminate web () having a maximum elastic extensibility in a first direction of at least 40%, preferably at least 60%, and most preferably at least 80%, under a peak load F, and an absorbent core () attached to the elastic laminate web. The method including the steps of providing a continuous length of the elastic laminate web (); advancing the continuous length of the elastic laminate web in a direction of travel (A) corresponding to the first direction; attaching individual absorbent cores () to the continuous length of the elastic laminate web at spaced intervals, and forming individual articles () from the thus assembled individual absorbent cores and the continuous length of said elastic laminate web. The continuous length of the elastic laminate web () is maintained under a tensioning load Fin the direction of travel during the advancing, with the tensioning load Fsatisfying the condition: 0.03 F≦F≦0.25 F.
