Abstract

A method of handling an adhesive laminate, wherein the adhesive laminate is provided releasably adhered to a first web, comprising a plurality of cut or punched sections and wherein adjacent sections of the adhesive laminate remain joined to one another in the longitudinal direction of the web through one or more tie points. A first supporting structure and a second supporting structure adjacent to the first supporting structure are provided. The first web is led over the first supporting structure. A second web is provided and led over the second supporting structure, wherein the second web is oriented such that the release surface of the second web faces the first supporting structure. A leading portion of a first section of adhesive laminate from the first web is attached to the release surface of the second web and the second web is advanced such that the first section of the adhesive laminate is detached from a second section of adhesive laminate and the leading edge of the second section of adhesive laminate is adhered to the second web in a spaced apart configuration from the trailing edge of the first section of the adhesive laminate. A transdermal drug delivery device prepared by such a method.
