DEVELOPMENTS IN MANUFACTURE OF COPPER WIRE 201 



The magnet wire drawing machine is a high speed twelve die mul- 

 tiple head machine of eight wire drawing units occupying 90 square 

 feet of floor space including the operating area. A close-up view of two 

 heads of this machine is shown by Fig. 13. Fifty-one square feet of

floor space are required for a single unit (one head) commercial machine 

 of the same die capacity. The saving in investment in this case is 

 even greater than for the heavy and intermediate types of machines. 

 The use of these compact machines and overhead monorail equipment 

 for transporting material instead of using trucks with large aisles has 

 permitted the installation of the wiredrawing mill in less than one fourth 

 of the building area which would have been required if commercial 

 equipment had been purchased. 



General Plant Features 



The present connected load of the motors in the Rod and Wire Mill 

 is about 6000 horse power for which it was necessary to enlarge the 

 main power plant. A 700 foot tunnel connects the power plant with 

 the Rod and Wire Mill in which are laid pipes for carrying hot and 

 cold water, steam, gas, and air and lead covered power cables.
