A method for making a layered elastic substrate (220) includes advancing a first substrate layer (238) and a second substrate layer (240) in a machine direction. An elastic material is advanced in the machine direction in a stretched state. The elastic material (206) may be bonded to the first substrate layer (238) and the second substrate layer (240) in a stretched state to form a layered elastic substrate (220). The layered elastic substrate may advance through a first metering device (250) at speed, VI, and through a second metering device (252) at speed, V2, subsequent to advancing through the first metering device, wherein VI is greater than V2. As a result, the elastic material, and thus the layered elastic substrate (220), may be stretched to a first elongation at the first metering device and relaxed to a second elongation at the second device. The layered elastic substrate (220) is cut and bonded to a continuous length of web material. |
