285 (#371) ############################################ 1 DRAWING AND SPINNING MACHINERY Needless to say, 3 is much the best method. As a rule the shed and equipment will be worked out in the following order and finally the necessary adjustments made :- 1. Selection of sets of machinery in accordance with the nature of the material to be spun and the required output; 2. Arrangement of (a) the individual machines, (6) the sets of machines, and (c) drawing, spinning and twisting machinery to ensure the least possible handling of the material ; 3. The scheming of the roof with its supports if a shed and of the several floors if a storied building ; 4. The scheming of the drives and the power plant ; 5. Selection of the material and scheming of the surface of the shed floors ; 6. Arrangement of the trolley ways or overhead rails if required ; 7. Scheming of the heating and artificial lighting with water leads where necessary ; 8. Scheming of the ventilation and atmosphere control; 9. Scheming of such storage as may be necessary for (a) tops; (b) rovings; and (c) yarns ; 10. Scheming of yarn warehouse, packing, etc. Upon each one of these points a book could almost be written, and almost every section calls for research. If, for example, a spinner could depend upon the spinning room atmosphere for the con- ditioning of the yarns and never attempt to add condition locally, many most grievous and costly claims for damaged pieces would never arise. 285
