Abstract
An apparatus and method for making a support device, typically of synthetic plastic material, in which fibrous backing members are concurrently cut, positioned, and bonded to the support device as it is formed. In an injection molding machine, a punch and die assembly cuts the backing members from a strip of fibrous material and automatically positions the members adjacent one side of the mold cavity. Molten plastic material is injected into the mold cavity and forms the support device while simultaneously adhering to the fibrous backing members. The completed support device has a body portion with load carrying members projecting from the forward surface thereof. The fibrous backing members are molded directly onto the rear surface of the body portion and a coating of adhesive material is placed on the outer surface of the fibrous backing members for securing the completed support device to a surface such as a wall or door.
