MOLD AND CORE EQUrPMENT. 



This equipment is of great importance. In designing a non-skid 

 tread considerable expense can be saved by using a design which 

 will eliminate, as far as possible, all hand work in connection 

 with the manufacture of the mold. This can often be done with- 

 out aflfeclmg the qualities of the non-skid design. Collapsible 

 cores are used, and as air bags are necessary for curing cord 

 tires a complete mold equipment for their manufacture should 

 be installed. Additional e<iuii)ment will include base rings for 

 molds, bead placing ring.-; and bead molds. 



EMERGENCY BOOM. 



The emergency or hospital room is located on this floor, 

 adjacent to the elevator. While the more serious accidents 

 occur in the mill and calender room on the main floor, minor 

 accidents arc more frequent on the second and third floors. This 

 room should be sanitary, and in fact a miniature hospital com- 

 pletely equipped and managed by a competent physician. 



THIRD FT-OOR. 



The ihird floor is devoted entirely to lubes. The tube vul- 

 canizcr should be equipped with e.xlra inside carriages and 

 transfer carriages to secure full production. Wrapping and 

 stripping lathes, skiving machines, nut tighteners, flap machines 

 and deflating machines are all necessary equipment. Building 

 tables and splicing equipment, where the acid cure is used, can 

 be built at the plant. 



The plant here outlined provides for an initial capacity of 500 

 casings and tubes per day and is designed for an ultimate capa- 

 city of 2000 tires a day without any material changes in the 

 building. Additional equipment and three shifts will be necessary 

 to reach this production. 



Below arc outlined the various operations from the receiving to 

 the shipping room, showing the machinery, connections and 

 small tools required for each operation, and followed by pertinent 

 remarks.

Remarks. 



All material received should be inspected before 



entering the factory. 

 Fairly large room. Uniform temperature should 



be kept at all times. 

 Located in the basement. Should be cool and 



protected from the sun. 

 An inspecting machine should be installed which 



would also measure fabric so that claims could 



be made in case of shortages. 



ans, scoop This should be in a separate building, absolutely 

 ►rs, castor- fireproof, divided by fire-wall. The equipment 

 should not be direct-drive type on account of 

 the fire hazard. A motor is located in a small 

 pent house to operate both churns and spreader 

 by belt drive.
