Abstract
A storage reel for copper coated iron welding electrode wire comprises a tubular core of plywood having opposite ends and flanges of plywood at the opposite ends. A vapor barrier layer preferably having outer layers of aluminum foil and an intermediate layer of paper is bonded to the axially inner surfaces of the flanges to provide a barrier against the migration of moisture and other vapor contaminate in the wood material to the welding electrode wire wound on the reel. A method of constructing the reel is also disclosed.
Claims39
A storage reel for copper clad steel welding wire comprising, core means of wood material for winding said welding wire upon said reel, said core means having an outer surface and axially opposite ends, flange means for confining said welding wire upon said core means at each of said opposite ends of said core means having axially inwardly facing inner surface, said wire being wound on said reel about said outer surface of said core means and between said inner surfaces of said flanges means, and vapor barrier means for preventing moisture migration covering at least said inner surfaces of said flange means.
A storage reel for copper clad steel welding wire comprising, a tubular core of wood material having an outer surface and axially opposite ends, a flange member of wood material at each of said opposite ends, each of said flange members having axially inwardly facing inner surface means for engaging said tubular core including an inner surface portion extending radially outwardly of said outer surface of said core, means interconnecting said flange members with said core, and a vapor barrier of laminated sheet material covering said outer surface of said tubular core and at least said inner surface portion of each of said flange members.
A method of manufacturing a storage reel for welding wire comprising providing a reel having core and end flanges of wood material defining an annular channel for confining welding wire wound onto said reel, and covering said channel with a vapor barrier layer, said vapor barrier layer being substantially impervious to vapor, stable at high temperature and not adhering to welding wire.
A method of constructing a storage reel for welding wire comprising, providing, a tubular core of wood material having opposite ends, providing a pair of flanges of wood material, covering the outer surface of said core and one side of each flange with a laminate including an exposed layer of aluminum, and attaching said flanges to said opposite ends of said core with said one sides thereof facing one another.
