Core corrector

Abstract

A strapping core corrector comprising a first arcuate side, a second arcuate side, at least open slide coupled therebetween, and an expansion member including an opening is provided. The first arcuate side and the second arcuate side include a flange and a collar disposed substantially perpendicular to one another. The at least one slide is coupled to an end of the first arcuate side and the second arcuate side. The expansion member is coupled to the first arcuate side and the second arcuate side and it configured to expand the first arcuate side and the second arcuate side to correct a deformed core of a roll of strapping, and the opening is sized to fit around a spindle of a package strapping dispenser.

1 . A strapping core corrector comprising:
 a first arcuate side including a first flange coupled substantially perpendicularly to a first collar;   a second arcuate side including a second flange coupled substantially perpendicularly to a second collar;   at least one slide coupled to an end of the first arcuate side and an end of the second arcuate side, wherein the at least one slide is movably coupled to one or both of the first arcuate side and the second arcuate side, wherein the first arcuate side couples to the second arcuate side via the at least one slide in a manner in which the first flange and the second flange are approximately parallel and the first collar and the second collar are approximately parallel in about a same plane; and   a rotatable expansion means operatively coupled to the first arcuate side and the second arcuate side, wherein the rotatable expansion means is configured to apply a force to the first arcuate side to bias the first arcuate side away from the second arcuate side.   
     
     
         2 . The strapping core corrector of  claim 1  further comprising a quick expansion member configured to temporarily disengage a shaft of the rotatable expansion means to allow manual movement of the first arcuate side away from the second arcuate side. 
     
     
         3 . The strapping core corrector of  claim 2  wherein the quick expansion member comprises a wing nut and a pin including threads disposed on one side of the pin. 
     
     
         4 . The strapping core corrector of  claim 2  wherein the quick expansion member comprises a threaded knob and a pin including threads disposed on one side of the pin. 
     
     
         5 . The strapping core corrector of  claim 2  wherein a user can use the quick expansion member to provide the initial expansion of the core corrector and the user can use the expansion member to provide additional tension on the deformed core to aid in correcting the deformed core of the roll of package strapping. 
     
     
         6 . The strapping core corrector of  claim 1  wherein the rotatable expansion means comprises at least one threaded shaft having a first threaded shaft end rotatably connected to one of the first arcuate side or the second arcuate side and a second threaded shaft end connected to a spline such that rotation of the spline in a first direction biases the first arcuate side away from the second arcuate side. 
     
     
         7 . The strapping core corrector of  claim 1  wherein the opening of the rotatable expansion means is sized to fit around a spindle of a package strapping dispenser. 
     
     
         8 . The strapping core corrector of  claim 1  wherein the at least one slide is fixedly coupled to one of the first arcuate side or the second arcuate side. 
     
     
         9 . The strapping core corrector of  claim 8  wherein the at least one slide is slidably coupled to another of the one of the first arcuate side or the second arcuate side. 
     
     
         10 . The strapping core corrector of  claim 1  wherein the first arcuate side and the second arcuate side are connected to be substantially circular. 
     
     
         11 . The strapping core corrector of  claim 1  wherein the opening is configured to be a handle for carrying the core corrector. 
     
     
         12 . The strapping core corrector of  claim 1  wherein a user can place a leverage tool in the opening to provide additional force to the deformed core. 
     
     
         13 . A method comprising:
 placing a core corrector in a middle of the deformed core of the roll of package strapping;   utilizing a quick expansion member and at least one slide coupled to a first arcuate side and a second arcuate side to slide the first arcuate side and the second arcuate side into contact with the deformed core to provide an initial fit of the core corrector on the deformed core;   utilizing a rotatable expansion means including an opening in the middle thereof, operatively coupled to the first arcuate side and the second arcuate side to provide a biased fit of the core corrector on the deformed core;   expanding the first arcuate side from the second arcuate side to correct the deformed core; and   placing the core corrector including the corrected deformed core on a package strapping dispenser, wherein the opening of the core corrector is sized to fit around a spindle of the package strapping dispenser.   
     
     
         14 . The method of  claim 13  wherein the expanding the first arcuate side from the second arcuate side to correct the deformed core comprises applying linear force by the rotatable expansion means to expand the first arcuate side from the second arcuate side. 
     
     
         15 . The method of  claim 13  wherein the utilizing the quick expansion member comprises the quick expansion member automatically disengaging to effect manual expansion of the rotatable expansion means. 
     
     
         16 . The method of  claim 13  wherein the utilizing the quick expansion member comprises manually engaging and disengaging the quick expansion member.
