Wrapped driving anvil

Abstract

An anvil is provided for use in a blind fastening system. The anvil is made using a process of wrapping a piece of wire stock around a mandrel. This process provides significant cost advantages compared to the process of machining the anvil.

The invention claimed is:  
     
         1 . An anvil for use with a fastening system, said anvil comprising: 
 a first portion having opposite first and second ends;    a second portion extending radially outwardly from said second end of said first portion; and    wherein said anvil is formed by a wrapping material around a mandrel.    
     
     
         2 . An anvil as defined in  claim 1 , wherein said anvil further includes a slot.  
     
     
         3 . An anvil as defined in  claim 2 , wherein said slot has an angle of sixty degrees or less.  
     
     
         4 . An anvil as defined in  claim 1 , wherein said material is wire.  
     
     
         5 . A method of wrapping an anvil for use in a fastening system comprising the steps of: 
 forming a piece of wire to create a first portion and a second portion, said second portion extending radially outwardly from said first portion;    cutting said wire to a predetermined length to form two free ends;    providing a mandrel; and    wrapping said wire around said mandrel.    
     
     
         6 . A method as defined in  claim 5 , further comprising the step of: 
 placing said mandrel and said wire within a groove of a brace.    
     
     
         7 . A method as defined in  claim 5 , further comprising the step of: 
 forcing said free ends against said mandrel such that said free ends are spaced apart from each other at a predetermined distance.
