A method for assembling disposable diaper pants, the method comprising the steps of: advancing a first continuous elastic laminate in a machine direction, the first continuous elastic laminate comprising an outer substrate comprising a first surface and an opposing second surface, an inner substrate comprising a first surface and an opposing second surface, and elastic material bonded between the first surfaces (162a, 164a) of the inner and outer substrates (162, 164); advancing a second continuous elastic laminate in the machine direction; providing a continuous length of absorbent cores; bonding the continuous length of absorbent cores between a continuous topsheet substrate and a continuous backsheet substrate; cutting the continuous topsheet substrate, the continuous backsheet substrate, and the continuous length of absorbent cores together along a cross direction to create discrete chassis, each chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, wherein the topsheet, the backsheet, and the absorbent core each comprise a first end region and an opposing second end region separated from each other by a central region, and comprising a longitudinal axis and a lateral axis, wherein the longitudinal axis is parallel with the machine direction, wherein the topsheet, the backsheet, and the absorbent core have equal longitudinal lengths, L; depositing the discrete chassis spaced apart from each other along the machine direction onto the first continuous elastic laminate and the second continuous elastic laminate; and sealing the first end regions of the absorbent cores by folding a portion of the first continuous elastic laminate into a facing relationship with the topsheets of each chassis, wherein first end regions (144, 148) of each topsheet, backsheet, and absorbent core are positioned between the folded portion of the first continuous elastic laminate and the second surface of the inner substrate. advancing a first continuous elastic laminate in a machine direction, the first continuous elastic laminate comprising an outer substrate comprising a first surface and an opposing second surface, an inner substrate comprising a first surface and an opposing second surface, and elastic material bonded between the first surfaces (162a, 164a) of the inner and outer substrates (162, 164); advancing a second continuous elastic laminate in the machine direction; providing a continuous length of absorbent cores; bonding the continuous length of absorbent cores between a continuous topsheet substrate and a continuous backsheet substrate; cutting the continuous topsheet substrate, the continuous backsheet substrate, and the continuous length of absorbent cores together along a cross direction to create discrete chassis, each chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, wherein the topsheet, the backsheet, and the absorbent core each comprise a first end region and an opposing second end region separated from each other by a central region, and comprising a longitudinal axis and a lateral axis, wherein the longitudinal axis is parallel with the machine direction, wherein the topsheet, the backsheet, and the absorbent core have equal longitudinal lengths, L; depositing the discrete chassis spaced apart from each other along the machine direction onto the first continuous elastic laminate and the second continuous elastic laminate; and sealing the first end regions of the absorbent cores by folding a portion of the first continuous elastic laminate into a facing relationship with the topsheets of each chassis, wherein first end regions (144, 148) of each topsheet, backsheet, and absorbent core are positioned between the folded portion of the first continuous elastic laminate and the second surface of the inner substrate.
