The Planning of a Cotton Mill for Tire Fabrics 



By G. Joseph Nord' 



THERE is no iron-clad rule that can be laid down as to the 

 proper design of a cotton mill maiuitacturing tire fabrics, 

 as this is a comparatively new branch of the textile industry 

 in which there has been a wide departure from the conventional 

 methods in the manufacture of cotton goods. Each manufacturer 

 or engineer usually has his own ideas as to the construction of

the mill building, the type or make of machinery and its position 

 in the mill. 



To familiarize the reader with what is considered a practical 

 lay-out of a modern tire fabric plant, I will give a description of 

 a 5,000-spindle mill designed to produce 23 by 5 by 3-cord fabric 

 and 23 by 23 builder fabric. 



There are several important matters that should be carefully 

 considered at the outset in connection with 

 planning a cotton mill ; some of these are 

 the following : 



1. The class of goods to be made. 



2. The size of the mill, as determined 

 by the number of spindles. 



3. The machines necessary to be oper- 

 ated in connection with this number of 

 spindles in order to produce the goods 

 desired. 



4. The space that this macliinery will 

 occupy. 



5. The extra expense to be incurred in 

 addition to the building and equipment of 

 the mill— the land to be purchased, ten- 

 ement houses to be erected, capital to be 

 left for the operation of the mill, etc. 



6. The total cost of the undertaking. 

 It is important, therefore, to plan each 



of the foregoing subjects and have specifi- 

 cations for them submitted to the proprie- 

 tors or directors before commencing to 

 plan the building. 



MILL BUILDING 



concrete which are superior to the ordinary type of slow-burning 

 construction. This type of building, if used with steel sash and 

 doors, is ideal for cotton manufacturing, as it gives an abundance 

 of light and an unyielding floor for machinery, the latter being a 

 very important factor in keeping machines in line and thereby 

 increasing their life and efficiency. 



POWER. HEAT AND LIGHT 

 Electrical power is generally found 

 to be more economical and the indi- 

 vidual drive, being no longer an experi- 

 ment on textile machinery, makes this 

 form of drive the most practical and 

 efficient. 



A successful heating system for a 

 textile mill must be constructed of the 

 best of material and well put together. 

 It must be elastic and easily con- 

 trolled ; have aljundant reserve capac- 

 ity ; be compact, durable and easily ac- 

 cessible for repairs. 



The condition of the atmosphere in 

 regard to moisture or humidity is an 

 important feature, and in addition to 

 the necessary warmth, a certain amount 

 of water must be carried in suspen- 

 sion in order that the materials in 

 process may be in the proper condi- 

 tion. One of the most valuable im- 

 provements along this line during recent years has been the use 

 of automatic regulation in connection with a humidifying appa- 

 ratus. Uniform moisture at all times is an absolute necessity, and, 

 of course, without automatic regulation this is not possible. 

 Humidity not only saves a big loss in weight, but also makes 

 better running work which in turn lessens the cost of production. 

 Electric lighting, of course, is the best system, and any good

For a 5,000-spindle mill a two-story building about 80 feet 

 wide and 250 feet long is most practical so as to eliminate as 

 far as possible the use of artificial light. 



The more recent designs of mill buildings are of reinforced

 there is no casting of shadows. 



FIRE PREVENTION 



It is very important that a mill should be so constructed as to 

 minimize the risk of fire, and so equipped that a fire may be 

 extinguished at the earliest possible moment. At the present
