Abstract:

The present invention provides an orthopedic casting article and a protective pad article having soft edges. In one embodiment, the article comprises a flexible sheet material impregnated or coated with two different resins. In an alternative embodiment, the article comprises an extruded sheet material comprising two different extruded materials. One of the resins or extruded materials is soft or resilient compared to the other resin or material. By selectively providing the softer materials at defined regions of the article the hardness of the region can be adjusted. The article may be in the form of an orthopedic casting tape or a protective pad comprising a fabric backing that is longitudinally impregnated or coated with two different curable resins. A harder, first curable resin is used to coat a longitudinally extending center region of the fabric backing; and a softer, second curable resin is used to coat at least one longitudinally extending edge region of the fabric backing. When the casting tape is wrapped around a limb the softer edge regions may be overlapped to form a soft, comfortable edge of the cured cast.
