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 an absorbent core, the method comprising steps of: advancing a continuous first substrate layer in a machine direction; advancing a continuous second substrate layer in the machine direction; stretching a plurality of elastic strands in the machine direction; positioning the stretched plurality of elastic strands between the first substrate layer and the second substrate layer to form a continuous elastic laminate; cutting the elastic laminate along the machine direction to form a first continuous elastic laminate and a second continuous elastic laminate, wherein the first continuous elastic laminate defines a width, W1, extending in the cross direction; separating the first continuous elastic laminate and the second elastic laminate in the cross direction; bonding a plurality of chassis with the first continuous elastic laminate and the second continuous elastic laminate; providing a press member comprising a pattern surface that defines a length, L, that extends in a cross direction and wherein the length, L, of the pattern surface is greater than 30% of W1; providing an anvil; partially melting a portion of the first substrate layer and a portion of the second substrate layer; positioning the press member such that the length, L, of the pattern surface extends across the plurality of stretched elastic strands; and bonding the first continuous elastic laminate and the second continuous elastic laminate together with a single, contiguous bond extending in the cross direction for length L by compressing the partially melted portion of the first substrate layer, the plurality of stretched elastic strands, and the partially melted portion of the second substrate layer between the pattern surface and the anvil, and wherein adjacent elastic strands from the first continuous elastic laminate and the second continuous elastic laminate are interposed with each other through a thickness of the bond.
