A cover for a reel of welding wire comprises a sleeve having axially opposite ends extending across the outer peripheries of the flanges of the reel and having radially inwardly open circumferentially extending recesses interengaging with the flanges to releasably axially retain the sleeve on the reel and to seal the space between the flanges so as to protect welding wire wound about the hub of the reel between the flanges from exposure to air and moisture. Seals are provided between the recesses and reel flanges for the latter purpose. In accordance with another embodiment, the cover comprises two portions which snap-lock together to completely enclose the reel. The reel and cover are relatively rotatable and in accordance with another aspect of the invention the cover can remain on the reel during use and is provided with an integral or detachable nose which supports the wire during unwinding thereof from the reel.
A cover for a reel of welding wire, said reel including a hub having an axis and axially spaced apart first and second flanges each extending radially outwardly from said hub and having a radially outer periphery, said hub and flanges providing a space for winding wire about said hub between said flanges, said cover comprising wall means including a wall adapted to extend circumferentially about and axially across said outer peripheries of said first and second flanges, and said wall means including means for sealing said space against the ingress of ambient air thereinto said first and second flanges respectively have first and second axially outer ends and said hub has corresponding first and second axially outer ends and an opening axially therethrough, said wall being a first wall, said wall means including a tubular second wall adapted to extend through said opening in said hub, said first and second walls each having axially opposite first and second ends respectively axially outwardly of said first and second ends of said flanges and said hub, said wall means including third and fourth walls respectively extending radially between said second ends of said first and second walls, whereby said first, second third and fourth walls enclose said reel and provide said means for sealing said space.
A cover for enclosing a reel of welding wire, saint reel including a hub having an axis and an axial bore therethrough and first and second flanges axially spaced apart and extending radially outwardly from said hub and having axially outer sides and radially outer peripheries, said hub and flanges providing a space for winding wire about said hub between said flanges, said cover comprising releasably interengagable first and second cover portions adapted to be assembled to enclose said reel therein, said cover portions when assembled comprising inner wall means extending through said bore and having axially opposite first and second ends, outer wall mean extending about the outer peripheries of said flanges and having axially opposite first and second ends first end wall means axially outwardly of said first flange and between said first ends of said inner and outer wall means and second end wall means axially outwardly of said second flange and between said second ends of said inner and outer wall means. said cover and said reel are independently rotatable relative to said axis, said outer wall means including an opening therethrough for feeding wire on said reel through said cover, and positioning means inwardly of said opening for positioning said wire relative to said opening.
A cover for enclosing a reel of welding wire, said reel including a hub having an axis and an axial bore therethrough and first and second flanges axially spaced apart and extending radially outwardly from said hub and having axially outer sides and radially outer peripheries, said hub and flanges providing a space for winding wire about said hub between said flanges, said cover comprising releasably interengagable first and second cover portions adapted to be assembled to enclose said reel therein, said cover portions when assembled comprising inner wall means extending through said bore and having axially opposite first and second ends, outer wall means extending about the outer peripheries of said flanges and having axially opposite first and second ends, first end wall means axially outwardly of said first flange and between said first ends of said inner and outer wall means and second end wall mean axially outwardly of said second flange and between said second ends of said inner and outer wall means, said cover and said reel are relatively rotatable relative to said axis, said outer wall means including an opening therethrough for feeding wire on said reel through said cover, and positioning means inwardly of said opening for positioning said wire relative to said opening. and sealing means for sealing said opening against the ingress of ambient air into said cover.
A cover for enclosing a reel of welding wire, said reel including a hub having n axis and an axial bore therethrough and first and second flanges axially spaced apart and extending radially outwardly from said hub and having axially outer sides and radially outer peripheries, said hub and flanges providing a space for winding wire about said hub between said flanges, said cover comprising releasably interengagable first and second cover portions adapted to be assembled to enclose said reel therein said cover portions when assembled comprising inner wall means extending through said bore and having axially opposite first and second ends, outer wall means extending about the outer peripheries of said flanges and having axially opposite first and second ends, first end wall means axially outwardly of said first flange and between said first ends of said inner and outer wall means and second end wall means axially outwardly of said second flange and between said second ends of said inner and outer wall means said inner wall means includes first and second inner wall portions respectively extending axially inwardly from said first and second end wall means and having axially inner ends, said outer wall means includes first and second outer wall portions respectively extending axially inwardly from said first and second end wall means and having axially inner ends, said first end wall means and said first inner and outer wall portions providing said first cover portion, and said second end wall means and said second inner and outer wall portions providing said second cover portion, and means for releasably interconnecting said axially inner ends of said inner wall portions and said axially inner ends of said outer wall portions.
