A method for making a layered elastic substrate, the method comprising the steps of: advancing a first elastic material in a machine direction to a first metering device at a speed, V1, wherein the first elastic material is in a stretched state; advancing a second elastic material in the machine direction to a second metering device at a speed, V2, wherein the second elastic material is in a stretched state; advancing a first substrate layer in the machine direction, the first substrate layer having a first surface and an opposing second surface; advancing a second substrate layer in the machine direction, the second substrate layer having a first surface and an opposing second surface; advancing the first elastic material, the second elastic material, the first substrate layer and the second substrate layer in the machine direction to a third metering device at a speed, V3; bonding the first and second elastic materials in the stretched states to the first surface of the first substrate layer and the first surface of the second substrate layer at the third metering device to form a layered elastic substrate; and advancing the layered elastic substrate onto a fourth metering device, wherein the fourth metering device comprises a drum rotating about an axis of rotation, the drum having an outer circumferential surface moving at speed, V4; cutting the layered elastic substrate disposed on the fourth metering device in a cross direction to form discrete lengths of layered elastic substrate, the discrete lengths of layered elastic substrate having a first edge region and a second edge region separated by an inner region, wherein V1 is less than V2, wherein V3 is greater than V1 and V2, wherein V4 is less than V3, and wherein V4 is greater than V1 and V2.
