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.

[ What is claimed is:] [1.] An adhesive faceplate for an ostomy appliance comprising a barrier layer having first and second side surfaces and a tapered outer peripheral edge portion; said barrier layer being composed of a soft, tacky elastomer constituting a continuous first phase and liquid-absorbing hydrocolloid particles dispersed throughout constituting a discontinuous second phase; a covering layer of soft, flexible heat-sealable material having an inner portion extending along said first side surface of said barrier layer and having an integral outer portion extending outwardly beyond said peripheral edge portion of said barrier layer; a pressure-sensitive adhesive layer securing said inner portion of said covering layer to said first side surface of said barrier layer and also coating said outer portion of said covering layer; and a unitary release sheet removably covering both said second side surface of said barrier layer and said adhesive coating of said outer portion of said covering layer.
