Abstract:
1. A method for production of disposable pant diapers, the method comprising: providing a continuous length of a substantially homogeneous elastic laminate web having a maximum elastic extensibility in a first direction of at least 40% under a peak load F advancing said continuous length of said elastic laminate web in said first direction and attaching individual absorbent cores to said continuous length of said elastic laminate web at spaced intervals, while maintaining said continuous length of said substantially homogeneous elastic laminate web under a tensioning load F folding said substantially homogeneous elastic laminate web with the individual absorbent cores attached thereto onto itself to form a fold edge and an open edge of the pant diapers; maintaining said continuous length of said substantially homogeneous elastic laminate web under the tensioning load F said tensioning load F welding the substantially homogeneous elastic laminate web to define weld lines intermittently transverse to the first direction and severing the individual pant diapers along the weld lines; wherein: said substantially homogenous elastic laminate web includes two layers having respective levels of elasticity different from one another, and said substantially homogenous elastic laminate web exhibits a non-linear load-strain curve relationship.
