Title: Method for manufacturing contoured and laminated materials

Abstract: A method for manufacturing end products such as wound dressings, surgical dressing, fixation wafers for prostheses, ostomy wafers, shoe inner-soles, and other laminated and contoured devices using a contouring and laminating station, a delaminating station, a driving station and a cutting station. A first outer layer having a backing film protected by a support layer is attached to a subject layer having predetermined malleable properties on one surface of the adhesive material. A second outer layer is attached on an opposing surface of the subject layer. As the layers are attached, the subject layer is contoured at the contouring and laminating station to produce a first intermediate product. The support layer is removed to produce a second intermediate product at a delaminating station. The second intermediate product is driven by the driving station to the cutting station to be cut into the end products.
