Abstract
A first substrate advances in the first direction and a second substrate advances in the second direction. The first substrate advances onto an outer circumferential surface of a drum in a stretched state. The first substrate may be cut into discrete lengths of elastic substrate. The drum may be configured with vacuum to hold the discrete length of elastic substrate in a stretched state. The second substrate may advance in the second direction by a conveyor. The conveyor includes a roller having a curved outer surface that deforms the second substrate so as to define a curve in the first direction. A tamper apparatus intermittently displaces a deformed portion of the second substrate into contact with a discrete length of elastic substrate on the outer circumferential surface of the drum. The discrete length of elastic substrate bonds with the second substrate and is removed from the drum.
