  • Patent number: 10478346
    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.

  • Patent number: 10426739
    Abstract: An adhesive patch assembly and method for making same. The assembly can include an adhesive patch and a release liner. The patch can include a backing and a skin-contact adhesive. The release liner can further include a first portion and a second portion separated by a hinge. The first portion can be positioned to overlay the backing of the patch when the release liner is folded upon the hinge, and the second portion can be positioned to underlie the skin-contact adhesive of the patch. The method can include positioning the patch on the release liner, such that patch is located on one of the first portion and the second portion of the release liner; and folding the release liner about to locate the patch between the first portion and the second portion of the release liner.
