Tubular warp beam with axial end flanges and reinforcing members

A warp beam particularly adapted for warping, section warping or winding of threads, yarns or like textile material or synthetic melt-spun polymeric plastic material comprising a metallic tube having opposite axial ends and inner and outer peripheral surfaces, a flange member at each of said tube ends, each flange member including a generally peripheral flange and an axial collar, each axial collar having an outer peripheral surface, each collar outer peripheral surface being in internal spaced relationship to an associated one of said tube end inner peripheral surfaces, an annular reinforcing member having inner and outer peripheral surfaces, each annular reinforcing member being located between an associated collar outer peripheral surface and an adjacent tube end inner peripheral surface, said annular reinforcing members surfaces effectively compensating for out-of-roundness of said tube resulting from manufacturing tolerances, means for securing said tube, flange members and reinforcing members together as a unified structure, each reinforcing member is a split ring formed by a transverse gap, and a weld closes each gap.
