Non-slip header for paper roll, and methods

Abstract

A paper roll having a non-slip surface on the end(s) of the roll, particularly large paper rolls such as those from a paper making processes. A header, having a non-slip coating on one side and an adhesive coating on the other side is applied to end(s) of the rolled paper. Microencapsulated materials are one suitable class of non-slip materials. The non-slip surface on the header improves stability of the roll, when stood on end, during transport, such as in cargo trucks.

1 . A wrapped roll or paper or other sheet material comprising:
 (a) a roll of paper or other sheet material having a first end and an opposite second end;   (b) an outer wrap of material wrapped circumferentially around the roll and crimped over the first end to form crimped portions;   (c) an outer header adhered to the crimped portions, the outer header comprising a base sheet, an adhesive coating on a first side of the base sheet against the crimped portions, and a non-slip coating on a second side of the base sheet.   
     
     
         2 . The wrapped roll of  claim 1  further comprising a second outer header adhered to crimped portions on the second end of the roll, the outer header comprising a base sheet, an adhesive coating on a first side of the base sheet against the crimped portions, and a non-slip coating on a second side of the base sheet. 
     
     
         3 . The wrapped roll of  claim 1 , wherein the non-slip coating has a static coefficient of friction such that, to move the roll, a force of at least about 80% of the weight of the roll is needed. 
     
     
         4 . The wrapped roll of  claim 3 , wherein the non-slip coating has a static coefficient of friction of at least 0.5. 
     
     
         5 . The wrapped roll of  claim 3 , wherein the non-slip coating has a static coefficient of friction of at least 2.0. 
     
     
         6 . The wrapped roll of  claim 3 , wherein the non-slip coating comprises encapsulated adhesive material. 
     
     
         7 . The wrapped roll of  claim 3 , wherein the base sheet comprises kraft paper. 
     
     
         8 . The wrapped roll of  claim 7 , wherein the non-slip coating comprises encapsulated adhesive material at a weight of about 1 to about 6.5 pounds per 1000 square foot ream. 
     
     
         9 . The wrapped roll of  claim 8 , wherein the non-slip coating comprises encapsulated adhesive material at a weight of about 5 pounds per 1000 square foot ream. 
     
     
         10 . The wrapped roll of  claim 3 , wherein the adhesive is hot melt, water based or solvent based. 
     
     
         11 . A method of wrapping a roll of paper or other sheet material, the method comprising:
 (a) circumferentially wrapping a wrap material around a roll of paper or other sheet material, with a portion of the wrap material extending axially past ends of the roll;   (b) folding the extending wrap material radially against the ends of the roll to form crimped portions; and   (c) adhering an outer header to the crimped portions, the outer header comprising a base sheet, an adhesive coating on a first side of the base sheet against the crimped portions, and a non-slip coating on a second side of the base sheet.   
     
     
         12 . The method of  claim 11 , further comprising, prior to folding the extending wrap material radially against the ends of the roll:
 (a) applying an inner header to the ends of the roll.   
     
     
         13 . The method of  claim 11 , wherein adhering an outer header to the crimped portions comprises:
 (a) adhering an outer header to the crimped portions having a non-slip coating with a static coefficient of friction such that, to move the roll, a force of at least about 80% of the weight of the roll is needed.   
     
     
         14 . The method of  claim 13 , wherein the non-slip coating has a static coefficient of friction of at least 0.5. 
     
     
         15 . The method of  claim 13 , wherein the non-slip coating has a static coefficient of friction of at least 2.0. 
     
     
         16 . The method of  claim 13 , wherein the non-slip coating comprises encapsulated adhesive material at a weight of about 1 to about 6.5 pounds per 1000 square foot ream. 
     
     
         17 . The method of  claim 13 , wherein the non-slip coating comprises encapsulated adhesive material at a weight of about 5 pounds per 1000 square foot ream. 
     
     
         18 . A header for protecting rolls of paper and other sheet goods, the header comprising:
 (a) a base sheet having a first surface and an opposite second surface;   (b) an adhesive coating on the first surface; and   (c) an encapsulated non-slip coating on the second surface.   
     
     
         19 . The header of  claim 18  being circular and having a diameter of at least 30 inches. 
     
     
         20 . The header of  claim 18 , wherein the base sheet is kraft paper. 
     
     
         21 . The header of  claim 20 , wherein the kraft paper has a weight of 10-100 pounds per 1000 square foot ream. 
     
     
         22 . The header of  claim 18 , wherein the non-slip coating has a weight of about 1 to about 6.5 pounds per 1000 square foot ream. 
     
     
         23 . The header of  claim 18 , wherein the non-slip coating has a weight of about 5 pounds per 1000 square foot ream. 
     
     
         24 . The header of  claim 18 , wherein the adhesive is a hot melt, water based or solvent based.
