ABSTRACT:
The present invention is directed generally to a fiber glass filament wound wheel. More particularly, the present invention is directed to a fiber glass filament wound wheel reinforced with an epoxy resin. Most specifically, the present invention is directed to a filament wound, resin, fiber glass reinforced wheel for use, for example, on a transport cart and to a method and apparatus for forming the wheel. The wheels of the invention are formed by a filament winding process wherein a continuous strand of fiber glass is coated with a suitable curable resinous binder, such as a liquid epoxy resin catalyst mixture, and is wound on a metal core between spaced side plates which are shaped to define the shape of the side walls of the finished wheel. The assembly is cured for a suitable period of time and the side plates are removed. A bearing assembly can then be inserted in the wheel in the aperture defined by the core and the wheel assembly can be placed on a transport truck. The filament wound, fiber glass resin reinforced wheel resists heat and contact with corrosive substrates and does not harm the surface of the floor over which the transport cart to which the wheels are attached rolls.
