Abstract
A faceplate for an ostomy appliance is disclosed in which a unitary release sheet covers both the bodyside (rear) surface of an adhesive skin barrier layer and the surrounding adhesive surface of an outwardly-projecting porous covering layer. The barrier layer is beveled to a feathered outer edge and the release sheet contacts the adhesive surface of the covering layer immediately adjacent the outer edge of said barrier layer. A continuous in-line method for making such faceplates is disclosed.
