Abstract
Abstract The disclosed structure comprises an elongated bandage of the wrap-around type. The bandage is composed of a plurality of superposed strips of cloth or the like, one of which carries plastic resin and another of which carries a hardener or catalyst. A barrier sheet is interposed between the strips to keep the resin and hardener separated, the barrier sheet being arranged to provide a multiplicity of openings over its surface upon manipulation of the package, whereby to bring the resin and hardener into contact uniformly over the surface of the bandage. Upon application of the bandage to a body part of the like, and upon setting of the resin, a rigid plastic bandage or splint is provided.
