A method for assembling portions of absorbent articles, the method comprising the steps of: advancing a first substrate in a machine direction at a speed, the first substrate comprising a first surface and an opposing second surface; pre-heating the first substrate; arranging the second surface of the first substrate and a die surface in a facing relationship, wherein the die surface comprises an outer circumferential surface of a roll, and wherein the die surface comprises cavities; rotating the roll; contacting the die surface with the first substrate; applying energy to a portion of the first substrate while advancing at the speed such that a softened material of the first substrate moves into the cavities of the die surface to form a zone of protrusions, wherein the zone of protrusions extends in the machine direction for a length, Lz, wherein each protrusion protrudes from the second surface of the first substrate to a distal end; and wherein the first substrate has a pitch length, PL, extending along the machine direction, wherein the length, Lz, of the zone of protrusions extends in the machine direction for less than the pitch length, PL; wherein a position of the die surface is adjustable in the cross direction.
