Apparatus and method for repairing out-of-round tubular cores, and tubular core and coiled strapping assemblies

Apparatus for repairing an out-of-round assembly comprising a tubular core member having a substantially circular closed loop configuration and material coiled thereon, comprising:

• a first arcuately configured member, having a predetermined radiused curvature, adapted to be disposed internally within a deformed, out-of-round tubular core member having a substantially circular closed loop configuration so as to be disposed in contact with a first internal peripheral surface portion of the deformed, out-of-round tubular core member;
• a second arcuately configured member, having a predetermined radiused curvature, adapted to be disposed internally within the deformed, out-of-round tubular core member so as to be disposed in contact with a second internal peripheral surface portion of the deformed, out-of-round tubular core member which is disposed substantially diametrically opposite the first internal peripheral surface;
• and
• an extensible/contractible device interconnecting said first and second arcuately configured members together for alternatively moving said first and second arcuately configured members toward each other to relatively CONTRACTED positions so as to permit said first and second arcuately configured members to be disposed internally within the deformed, out-of-round tubular core member, and for moving said first and second arcuately configured members away from each other to relatively EXTENDED positions so as to cause said first and second arcuately configured members to forcefully engage the first and second inner peripheral portions of the deformed, out-of-round tubular core member in order to return the deformed, out-of-round tubular core member, and the material coiled thereon, to a tubular member having a substantially true circular, closed loop round configuration.

In combination, a deformed out-of-round tubular member having a substantially circular closed loop configuration, and apparatus for repairing the deformed out-of-round tubular member having the substantially circular closed loop configuration, comprising:

• a deformed out-of-round tubular member having a substantially circular closed loop configuration;
• a first arcuately configured member, having a predetermined radiused curvature, adapted to be disposed internally within said deformed, out-of-round tubular member so as to be disposed in contact with a first internal peripheral surface portion of said deformed, out-of-round tubular member;
• a second arcuately configured member, having a predetermined radiused curvature, adapted to be disposed internally within said deformed, out-of-round tubular member so as to be disposed in contact with a second internal peripheral surface portion of said deformed, out-of-round tubular member which is disposed substantially diametrically opposite the first internal peripheral surface portion of said deformed, out-of-round tubular member;
• and
• an extensible/contractible device interconnecting said first and second arcuately configured members together for alternatively moving said first and second arcuately configured members toward each other to relatively CONTRACTED positions so as to permit said first and second arcuately configured members to be disposed internally within said deformed, out-of-round tubular member, and for moving said first and second arcuately configured members away from each other to relatively EXTENDED positions so as to cause said first and second arcuately configured members to forcefully engage said first and second inner peripheral portions of said deformed, out-of-round tubular member in order to return said deformed, out-of-round tubular member to a tubular member having a substantially true circular, closed loop round configuration.
