Abstract

A method of refurbishing a used hollow cylindrical core member of paperboard material for a roll of paper or other sheet material, includes removing a predetermined thickness of paperboard material from the outer surface of the core member to reduce the outside diameter thereof by an amount in the range of from about 0.002 to about 0.01 inches. A layer of paper with a thickness in the range of from about 0.002 to about 0.01 inches is then secured around the core member of reduced diameter, with the axially extending edges of the paper layer overlapping.

Claims

exact text as granted — not AI-modified
1 . A method of refurbishing a used hollow cylindrical core member of paperboard material for a roll of paper or other sheet material, including: 
 removing a predetermined thickness of paperboard material from the outer surface of the core member to reduce the outside diameter thereof by an amount in the range of from about 0.002 to about 0.01 inches, and    securing a layer of paper with a thickness in the range of from about 0.002 to about 0.01 inches around the core member of reduced diameter and causing axially extending edges of the paper layer to overlap.    
   
   
       2 . A method according to  claim 1  wherein the paper layer has a thickness in the range of from about 0.002 to about 0.005 inches.  
   
   
       3 . A method according to  claim 2  wherein the paper layer has a thickness of about 0.003 inches.  
   
   
       4 . A method according to  claim 1  wherein the paper layer is adhesively secured to the core member of reduced diameter.  
   
   
       5 . A refurbished hollow core member for a roll of paper or other sheet material having: 
 a core member of paperboard material having a diameter reduced from a required diameter by an amount in the range of from about 0.002 to about 0.01 inches, and    a layer of paper with a thickness in the range of from about 0.002 to about 0.01 inches secured around the core member of reduced diameter with its axially extending edges overlapping.    
   
   
       6 . A core member according to  claim 5  wherein the paper layer has a thickness in the range of from about 0.002 to about 0.005 inches.  
   
   
       7 . A core member according to  claim 6  wherein the paper layer has a thickness of about 0.003 inches.  
   
   
       8 . A core member according to  claim 5  wherein the paper layer is adhesively secured to the core member of reduced diameter.
