Abstract:
A first elastic material is advanced in a machine direction in a stretched state to a first metering device at a speed, V1. A second elastic material is advanced in the machine direction in a stretched state to a second metering device at a speed, V2. First and second substrate layers are advanced in a machine direction to a third metering at a speed, V3, 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, V4. V1 is less than V2, V3 is greater than V1 and V2, V4 is less than V3, and V4 is greater than V1 and V2.
