CORDING. 



The goods described on page , are corded by the machine 

 represented by No. 8. This may be done either while the 

 goods are being manufactured or afterwards. When the cords 

 are placed upon a single thickness, after it is manufactured, the 

 cords should be cemented with liquid gum. When they are 

 placed between two thicknesses of the goods, they do not require 

 cementing. In all cases the operation of cording is a very simple 

 one, adding but a very trifle to the expense of the goods. 



THREAD CUTTING. 



The cutting of thread from native gum-elastic has been 

 practiced for many years in foreign countries. The process 

 and machinery for doing it is very different from that used in 

 the United States for vulcanized thread. It is now cut in the 

 United States from the manufactured sheets of gum, of any 

 length desired, as represented by No. 9. This machine was 

 patented by Messrs. Tyre and Helm, of New Brunswick, New 

 Jersey, being an improvement upon the callender cutting ma- 

 chine first used, represented by No. 10. The expense of man- 

 ufacturing the vulcanized cord has become much less than that 

 of the native gum cord, to say nothing of the difference in 

 quality.
