A method for making an elastomeric laminate, the method comprising steps of: providing a first plurality of elastic strands wound onto a first beam; providing a second plurality of elastic strands wound onto a second beam; rotating a first roller about a first axis of rotation extending in a cross direction, the first roller comprising an outer circumferential surface comprising a surface speed V1; rotating a second roller about a second axis of rotation extending in the cross direction, the second roller comprising an outer circumferential surface comprising a surface speed V1, wherein the first roller and the second roller rotate in opposite directions, and wherein the first roller is adjacent the second roller to define a nip between the first roller and the second roller; advancing a first substrate and a second substrate through the nip; rotating the first beam to unwind the first plurality of elastic strands from the first beam in a machine direction at a speed V2, wherein the first plurality of elastic strands are separated from each other in the cross direction, and wherein V2 is less than V1; stretching the first plurality of elastic strands in the machine direction by advancing the first plurality of elastic strands from the first beam through the nip and between the first substrate and the second substrate; connecting the second plurality of elastic strands with a splicer member; rotating the second beam to unwind the second plurality of elastic strands from the second beam in the machine direction, wherein the second plurality of elastic strands are separated from each other in the cross direction; advancing the splicer member and the second plurality of elastic strands through the nip; connecting the splicer member with the first substrate subsequent to the step of connecting the second plurality of elastic strands with the splicer member and prior to the step of advancing the splicer member through the nip; and discontinuing advancement of the first plurality of elastic strands through the nip subsequent to advancing the splicer member through the nip.
