Wire replacement device

Abstract

A first guide guides a wire at a first position. A second guide guides the wire at a second position. A feeder feeds the wire from the first position to the second position. A length examiner examines the wire to be fed in length between the first and second positions and at downstream of the feeder.

What is claimed is:  
     
         1 . A wire replacement device comprising: 
 a first guide for guiding a wire at a first position;    a second guide for guiding the wire at a second position;    a feeder for feeding the wire from the first position to the second position; and    a length examiner for examining the wire to be fed in length between the first and second positions and at downstream of the feeder.    
     
     
         2 . A wire replacement device according to    claim 1   , wherein 
 the feeder includes a first roll to be detached from the wire.    
     
     
         3 . A wire replacement device according to    claim 1   , wherein 
 the length examiner includes a second roll to be detached from the wire.    
     
     
         4 . A wire replacement device according to    claim 1   , further comprising: 
 a third guide for guiding the wire between the first and second positions.    
     
     
         5 . A wire replacement device according to    claim 4   , wherein 
 the third guide is variable in length.    
     
     
         6 . A wire replacement device according to    claim 5   , wherein 
 the third guide includes a first nozzle, and a second nozzle fitted to the first nozzle for movement.    
     
     
         7 . A wire replacement device according to    claim 6   , further comprising: 
 an actuator including a cylinder for movement of the second nozzle.    
     
     
         8 . A wire replacement device according to    claim 7   , further comprising: 
 a fourth guide for guiding the second nozzle.
