Apparatus for forming a transdermal drug device |
摘要 |
Disclosed is a method and apparatus for forming a transdermal drug delivery device from a multilayer web comprised of a backing layer, a drug-containing pressure sensitive adhesive layer, and a release layer or liner in which cutting is progressively achieved along a line coplanar with the axes of a cutting roller and anvil roller counter-rotating in proximity to each other. In one embodiment, cutting is achieved completely through the web about the periphery of the transdermal drug delivery device, while simultaneously achieving a scoring only of the release liner without penetration of the pressure sensitive adhesive layer or backing layer. In an alternate embodiment there are two arrangements of rollers. A first arrangement has a cutting edge for scoring the web. After scoring, the web is passed to a second arrangement for cutting through the web to result in the transdermal drug delivery device.
