Wire containment apparatus for wire drawing machines

Abstract

A wire drawing machine is provided with a pressure roller in the form of a roller sized to extend substantially across the width of the capstan and engage multiple turns of wire thereon in a lower quadrant on the exit side of the capstan. The pressure roller is mounted for pivoting about a horizontal axis parallel to the axis of the capstan, and for automatic angular positioning and alignment as contact is made with the wraps of wire on the capstan.

We claim:  
     
         1 . A wire drawing machine comprising: 
 a draw die;    a capstan mounted for rotation about a horizontal axis and positioned for drawing wire through the draw die, the capstan having an upper wire-entry side and a lower wire-exit side and having a width operative to carry wrapped wire thereon; and    a roller connected for pivoting about a horizontal axis parallel to the axis of the capstan and about a second axis orthogonal thereto for engaging wire on the lower exit side of the capstan, the roller being sized to substantially overlap the width of the capstan and engage the wire wrapped thereon.    
     
     
         2 . The wire drawing machine as defined in  claim 1  in which said roller is further connected for pivoting about a third axis orthogonal to said horizontal axis and said second axis.
