Abstract

See full text

The method includes rotating a drum about an axis of rotation. A discrete length of elastic substrate is positioned on the outer circumferential surface of the rotating drum, wherein the discrete length of elastic substrate is in a stretched state and defines a first length. The discrete length of elastic substrate may be defined by a first end region, a second end region, and a central region separating the first and second end regions. The method may comprise applying vacuum pressure to the first, second, and central regions of the discrete length of elastic substrate. Vacuum pressure may be reduced on the first and second end regions such that the discrete length of elastic substrate consolidates to a second length that is less than the first length.
