A method for assembling disposable pant diapers, each pant diaper comprising a chassis having a first end region and an opposing second end region separated from each other by a central region, and having a longitudinal axis and a lateral axis, the chassis comprising: a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, the method comprising steps of: advancing a first continuous elastic laminate along a machine direction, the first continuous elastic laminate having an outer longitudinal edge and an inner longitudinal edge; advancing a second continuous elastic laminate along the machine direction, the second continuous elastic laminate having an outer longitudinal edge and an inner longitudinal edge, wherein the first continuous elastic laminate is separated in a cross direction from the second continuous elastic laminate to define a gap between the inner longitudinal edge of the first continuous elastic laminate and the inner longitudinal edge of the second continuous elastic laminate; depositing a plurality of chassis spaced apart from each other along the machine direction across the gap and onto the first continuous elastic laminate and the second continuous elastic laminate; folding each chassis along the lateral axis to position the first continuous elastic laminate into a facing relationship with the second continuous elastic laminate and defining uncovered regions of the second continuous elastic laminate intermittently spaced between the chassis along the machine direction and having a width, W, extending in the cross direction defined by a distance extending between the inner longitudinal edge of the first continuous elastic laminate and the inner longitudinal edge of the second continuous elastic laminate; advancing the first continuous elastic laminate in the facing relationship with the second continuous elastic laminate through a nip defined between a cutting roll and an anvil roll wherein the cutting roll includes a blade having a distal edge extending in the cross direction and the machine direction; and pressing the distal edge of the blade against the first continuous elastic laminate and the second continuous elastic laminate in the nip to remove discrete pieces of trim material from the uncovered regions of the second continuous elastic laminate and simultaneously cut the first and second continuous elastic laminates in the cross direction to form discrete pant diapers wherein a maximum width of the second continuous elastic laminate is greater than a maximum width of the first continuous elastic laminate.
