Article, apparatus and method for attachment of a roll of web material to a treated core

Abstract

An article, apparatus and method for attaching a roll of web material to a treated core is disclosed. The article includes a core pre-treated with adhesive and the apparatus includes an adhesive, a conveyor, an applicator unit and roller drums. The method includes activating a treated core with adhesive, aligning the activated area of the treated core with a tail end of the roll of web material, adhering the tail end of the roll of web material with the activated area of the treated core, and winding the roll of web material around the treated core.

1 . An apparatus for attaching a roll of web material to a core, the apparatus comprising: 
 a conveyor for conveying a pre-treated core with adhesive into a winder;    an applicator unit to activate an area of the pre-treated core with adhesive; and    roller drums to align a tail end of the roll of web material onto the activated area of the pre-treated core with adhesive;    wherein the winder winds the roll of web of material onto the pre-treated core with adhesive.    
     
     
         2 . The apparatus of  claim 1 , further comprising a clamp to hold the pre-treated core with adhesive in position.  
     
     
         3 . The apparatus of  claim 1 , wherein the applicator unit is a sprayer, roller, brush, wiper, or other suitable applicator.  
     
     
         4 . A method for attaching a roll of web material to a core pre-treated with adhesive, the method comprising the steps of: 
 activating the core pre-treated with adhesive (before attaching the roll of web material) to create an activated area of the core pre-treated with adhesive;    aligning the activated area of the core pre-treated with adhesive with a tail end of the roll of web material;    adhering the tail end of the roll of web material with the activated area of the core pre-treated with adhesive; and    winding the roll of web material around the core pre-treated with adhesive.    
     
     
         5 . A roll of web material attached to a core (pre-treated with adhesive) made by the process of: 
 using a core pre-treated with adhesive;    activating the core pre-treated with adhesive (before attaching a tail end of the roll of web material to the core pre-treated with adhesive) to create an activated area of the core pre-treated with adhesive;    aligning the activated area of the core pre-treated with adhesive with a tail end of the roll of web material;    adhering the tail end of the roll of web material with the activated area of the core pre-treated with adhesive; and    winding the roll of web material around the core pre-treated with adhesive.    
     
     
         6 . A roll product of web material comprising: 
 a core pre-treated with adhesive; and    a roll of web material which is wound onto the core pre-treated with adhesive after the core pre-treated with adhesive is activated.    
     
     
         7 . A core comprising: 
 an adhesive applied onto the core (to adhere a roll of web material).    
     
     
         8 . The core of  claim 7 , wherein the adhesive is sprayed.  
     
     
         9 . The core of  claim 7 , wherein a top-ply web that is pre-treated with adhesive is bonded to the core.  
     
     
         10 . The core of  claim 7 , wherein the adhesive is activated by water.  
     
     
         11 . The core of  claim 1 , wherein the adhesive is sensitive to pressure.  
     
     
         12 . The core of  claim 7 , wherein the adhesive is sensitive to heat.  
     
     
         13 . The core of  claim 7 , wherein the adhesive is polyvinyl alcohol or a polyvinyl acetate.  
     
     
         14 . The core of  claim 7 , wherein the adhesive is selected from the group consisting of water soluble hot melts, water dispersible hot melts, pressure sensitive hot melts, or any hot melt or other adhesive activated by water, heat, or pressure.
