Abstract

Methods of handling adhesive laminate patches. A first article, passed over a first supporting structure, includes disconnected adhesive laminate patches adhered to a first web, each patch being aligned over and adhered to a tab. A second web can be passed over a second supporting structure that is separated from the first supporting structure by a gap. The first article can be passed over the first supporting structure to lift a leading portion of a first tab and a first patch off of the first web together, such that the first tab facilitates transfer of the first patch across the gap. The first patch can then be adhered to the second web; and the second web can be advanced to transfer the first patch, and first tab, onto the second web to form a second article comprising patches aligned over tabs on the second web.
