Abstract
Systems and methods for manufacturing composite webs including a substrate with one or more discrete polymeric regions located thereon are disclosed. The discrete polymeric regions are deposited by transferring molten thermoplastic composition from depressions on a transfer roll to a substrate. Each of the discrete polymeric regions is further formed to include multiple structures formed thereon. Those structures may include, for example, stems (capped or otherwise), hooks (as part of a hook and loop fastening system), pyramids, etc.
