摘要:
A method for making a layered elastic substrate includes advancing a first substrate layer and a second substrate layer in a machine direction. An elastic material is advanced in the machine direction in a stretched state. The elastic material may be bonded to the first substrate layer and the second substrate layer in a stretched state to form a layered elastic substrate. The layered elastic substrate may advance through a first metering device at speed, V1, and through a second metering device at speed, V2, subsequent to advancing through the first metering device, wherein V1 is greater than V2. As a result, the elastic material, and thus the layered elastic substrate, 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 is cut and bonded to a continuous length of web material.
