Methods for making slip resistant file folders

Abstract

Methods for producing easily and securely gripped slip-resistant file folders, including file pockets and hanging folders. The methods include providing folder paper stock; conveying the folder paper stock in the process of folder manufacture; providing a curable slip-resistant material in a melt state; applying the slip-resistant material at predetermined areas of the folder paper stock; and curing the slip-resistant material; such that the slip-resistant portion comprises cured slip-resistant material. Another method includes providing folder paper stock; providing embossing dies in spaced, operable, mating relationship; positioning the folder paper stock appropriately in the embossing dies; applying force to at least one of the embossing dies so as to decrease the spaced relationship; and deforming the folder paper stock.

1 . A method of making a slip-resistant folder, said folder having a front flap having a first top edge, a rear flap connected to said front flap by a folder bottom, said rear flap having a second top edge, and a slip-resistant portion disposed on at least one of said flaps near said first or second top edge, said method comprising the steps of: (a) providing folder paper stock; (b) conveying said folder paper stock in the process of folder manufacture; (c) providing a curable slip-resistant material in a melt state; (d) applying said slip-resistant material at predetermined areas of said folder paper stock; and (e) curing said slip-resistant material; such that said slip-resistant portion comprises cured slip-resistant material.  
   
   
       2 . The method of  claim 1 , wherein said applying is by a method of printing.  
   
   
       3 . The method of  claim 1 , wherein said applying is by a method of spraying.  
   
   
       4 . A method of making a slip-resistant folder, said folder having a front flap having a first top edge, a rear flap connected to said front flap by a folder bottom, said rear flap having a second top edge, and a slip-resistant portion disposed on at least one of said flaps near said first or second top edge, said method comprising the steps of: 
 (a) providing folder paper stock;    (b) providing embossing dies in spaced, operable, mating relationship;    (c) positioning said folder paper stock appropriately in said embossing dies;    (d) applying force to at least one of said embossing dies so as to decrease the spaced relationship; and    (e) deforming said folder paper stock.    
   
   
       5 . The method of  claim 4  further including the step of applying curable slip resistant material to at least a portion of said deformed places to increase slip resistance.  
   
   
       6 . The method of  claim 5  wherein said material is applied by spraying.  
   
   
       7 . The method of  claim 5  wherein said material is applied by printing.
