ABSTRACT:
A process is disclosed for making contoured hydrocolloid-containing adhesive dressings in which, in the final product, a soft pliant adhesive layer having one or more hydrocolloids dispersed therein is sandwiched between a top backing layer of stretchable film or fabric and a bottom release layer of flexible but substantially non-stretchable material. In a combined contouring and cutting step, the layers are compressed and heated to reshape the adhesive material and are simultaneously cut to form the finished dressing. In a preferred embodiment, three steps of laminating, contouring and cutting are performed simultaneously at a single station.
