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 with a constant width, W1, in a cross direction; 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 with a constant width, W2, in the cross direction; depositing a plurality of chassis spaced apart from each other along the machine direction onto the first continuous elastic laminate and the second continuous elastic laminate, wherein the first end regions of each chassis are connected with the first continuous elastic laminate, and the second end regions of each chassis are connected with 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 forming uncovered regions of the second continuous elastic laminate intermittently spaced between the chassis along the machine direction and having a width, W3, extending in the cross direction formed 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; removing discrete pieces of trim material from the uncovered regions of the second continuous elastic laminate after the folding step; and cutting the first and second continuous elastic laminates in the cross direction to form discrete pant diapers.
