A first elastic material is advanced in a machine direction in a stretched state to a first metering device at a speed, V. A second elastic material is advanced in the machine direction in a stretched state to a second metering device at a speed, V. First and second substrate layers are advanced in a machine direction to a third metering at a speed, V, along with the first and second elastic materials. The first and second elastic materials are bonded to the first and second substrate layers at the third metering device to form a layered elastic substrate. The layered elastic substrate is advanced to a fourth metering device at a speed, V. V is less than V, V is greater than V and V, V is less than V, and V is greater than V and V 1. A method for making a layered elastic substrate , the method comprising the steps of:{'b': '1', 'advancing a first elastic material in a machine direction to a first metering device at a speed, V, wherein the first elastic material is in a stretched state;'}{'b': '2', 'advancing a second elastic material in the machine direction to a second metering device at a speed, V, 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;{'b': '3', '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, V;'}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{'b': 4', '1', '2', '3', '1', '2', '4', '3', '4', '1', '2, 'advancing the layered elastic ...
