heat from I he clean comijound is remoxed in heat exchangers as the com- 

 pound is delivered to the machines. The compound is maintained at a])- 

 proximately 130°F by a closed recirculating water system thermostatically 

 controlled, Fig. 19. 



Layout of Principal Wire Mill Equipment 



The building used for wire drawing is ideally situated adjacent to the 

 cable manufacturing unit and has facilities for water, rail and motor truck

deliveries. The area is easily ventilated and has excellent illumination 

 provided by mercury vapor lamps, close to a high ceiling yet providing an 

 average of more than 20-foot candle illumination. Stroboscopic effect is 

 practically eliminated by staggering the lamps over separate phases of the 

 three-phase circuit. 



The No. 1 machines are located adjacent to the copper rod receival area. 

 The No. 2 drawing machines, nine of them in a row, are placed in the center 

 of the building. Along the wall, five annealing bases for the electric bell 

 type furnace are located. A bridge type crane handles all the material
