       3 . The bristle pack as in  claim 1 , in which at least some of said bristles are joined together by a clip. 
   
   
       4 . The bristle pack as in  claim 1 , in which said bristles are metallic. 
   
   
       5 . The bristle pack as in  claim 1 , in which said bristles are non-metallic. 
   
   
       6 . The bristle pack as in  claim 1 , in which said support is a flexible wire. 
   
   
       7 . The bristle pack as in  claim 1 , in which said plurality of bristles are formed into a plurality of groups of bristles, each of said groups of bristles being banded together adjacent said support opposite said fold. 
   
   
       8 . The bristle pack of  claim 7 , wherein at least one of said groups of bristles is banded by a clip. 
   
   
       9 . The bristle pack as in  claim 7 , in which at least one of said groups of bristles is banded by a sewn thread. 
   
   
       10 . A method of making a bristle pack comprising:
 folding a plurality of bristles over a support and forming a fold in each of said bristles; and   joining adjacent bristles together adjacent said support opposite said fold to secure said bristles to said support.   
   
   
       11 . The method as in  claim 10 , in which joining adjacent bristles together includes attaching a clip to at least some of said bristles. 
   
   
       12 . The method as in  claim 10 , in which joining adjacent bristles together includes sewing at least some of said bristles together into a group. 
   
   
       13 . The method as in  claim 10 , including forming said support into a ring. 
   
   
       14 . The method as in  claim 13 , including joining a first end and a second end of said support together. 
   
   
       15 . A brush seal comprising:
 a bristle pack including a support and a plurality of bristles folded over said support and defining a fold, said bristles being joined together adjacent said support opposite said fold.   
   
   
       16 . The brush seal as in  claim 15 , in which at least some of said bristles are joined together by a sewn thread. 
   
   
       17 . The brush seal as in  claim 15 , in which at least some of said bristles are joined together by a clip. 
   
   
       18 . The brush seal as in  claim 15 , in which said bristles are metallic. 
   
   
       19 . The brush seal as in  claim 15 , in which said bristles are non-metallic. 
   
   
       20 . The brush seal as in  claim 15 , in which said support is a flexible wire. 
   
   
       21 . The brush seal as in  claim 15 , in which said plurality of bristles are formed into a plurality of groups of bristles, each of said groups being banded together adjacent said support opposite said fold.
