Method for manufacturing disposable worn article

Abstract

A method for manufacturing a disposable worn article of the present invention includes: a first step of applying an adhesive on at least one of a first web and a second web; a second step of sandwiching an elastic member between the first and second webs and combining the first and second webs and the elastic member together, thereby producing a combined web; and a third step of melting a portion of at least one of the first and second webs and a portion of the elastic member, thereby reducing a shrinking force of the elastic member in the melted portion.

 a first step of applying an adhesive on at least one of a first web and a second web;    a second step of sandwiching an elastic member between the first and second webs and combining the first and second webs and the elastic member together, thereby producing a combined web; and    a third step of melting a portion of at least one of the first and second webs and a portion of the elastic member, thereby reducing a shrinking force of the elastic member in the melted portion.    
     
     
         2 . A method for manufacturing a disposable worn article, the method comprising: 
 a first step of applying an adhesive on at least one of a first web and a second web;    a second step of sandwiching an elastic member between the first and second webs and combining the first and second webs and the elastic member together, thereby producing a combined web; and    a third step of melting a portion of at least one of the first and second webs and a portion of the elastic member, thereby cutting off the elastic member.    
     
     
         3 . A method for manufacturing a disposable worn article, the method comprising: 
 a first step of applying an adhesive on at least one of a first web and a second web;    a second step of sandwiching an elastic member between the first and second webs and combining the first and second webs and the elastic member together, thereby producing a combined web; and    a third step of cutting off a portion of at least one of the first and second webs, and the elastic member.    
     
     
         4 . A method for manufacturing a disposable worn article according to  claim 1 , wherein: 
 the third step is performed by passing the combined web between an embossing roll having a plurality of protrusions and a counter roll; and    an interval of the protrusions in a direction of a rotation axis of the embossing roll is about 1 mm to 25 mm.    
     
     
         5 . A method for manufacturing a disposable worn article according to  claim 2 , wherein: 
 the third step is performed by passing the combined web between an embossing roll having a plurality of protrusions and a counter roll; and    an interval of the protrusions in a direction of a rotation axis of the embossing roll is about 1 mm to 25 mm.    
     
     
         6 . A method for manufacturing a disposable worn article according to  claim 3 , wherein: 
 the third step is performed by passing the combined web between an embossing roll having a plurality of protrusions and a counter roll; and    an interval of the protrusions in a direction of a rotation axis of the embossing roll is about 1 mm to 25 mm.    
     
     
         7 . A method for manufacturing a disposable worn article according to  claim 1 , wherein the third step is performed by passing the combined web between an embossing roll having a lattice portion and a counter roll.  
     
     
         8 . A method for manufacturing a disposable worn article according to  claim 2 , wherein the third step is performed by passing the combined web between an embossing roll having a lattice portion and a counter roll.  
     
     
         9 . A method for manufacturing a disposable worn article according to  claim 3 , wherein the third step is performed by passing the combined web between an embossing roll having a lattice portion and a counter roll.  
     
     
         10 . A method for manufacturing a disposable worn article according to  claim 1 , wherein a first charge is applied to an area of at least one of the first and second webs where the adhesive is to be applied, and a second charge different from the first charge is applied to the adhesive to be applied.  
     
     
         11 . A method for manufacturing a disposable worn article according to  claim 2 , wherein a first charge is applied to an area of at least one of the first and second webs where the adhesive is to be applied, and a second charge different from the first charge is applied to the adhesive to be applied.  
     
     
         12 . A method for manufacturing a disposable worn article according to  claim 3 , wherein a first charge is applied to an area of at least one of the first and second webs where the adhesive is to be applied, and a second charge different from the first charge is applied to the adhesive to be applied.  
     
     
         13 . A method for manufacturing a disposable worn article according to  claim 1 , wherein: 
 at least the first web includes a design area having at least one of a graphical design, a symbol and a character printed thereon; and    the elastic member located on at least a portion of the design area is cut off in the third step.    
     
     
         14 . A method for manufacturing a disposable worn article according to  claim 2 , wherein: 
 at least the first web includes a design area having at least one of a graphical design, a symbol and a character printed thereon; and    the elastic member located on at least a portion of the design area is cut off in the third step.    
     
     
         15 . A method for manufacturing a disposable worn article according to  claim 1 , wherein: 
 at least the second web includes an area on which a member is to be adhered; and    the elastic member located under at least a portion of the area is cut off in the third step.    
     
     
         16 . A method for manufacturing a disposable worn article according to  claim 2 , wherein: 
 at least the second web includes an area on which a member is to be adhered; and    the elastic member located under at least a portion of the area is cut off in the third step.    
     
     
         17 . A method for manufacturing a disposable worn article according to  claim 1 , wherein the elastic member is at least one of a string rubber, a flat rubber and a meshed rubber.
