271 (#357) ############################################ CHAPTER XI SETS OF DRAWING AND SPINNING MACHINERY-CALCU- LATIONS FOR OUTPUT SETS of drawing machinery may be designed in accord- ance with (a) Type of machine-Open, Cone, French ; or (6) Type of material to be treated—English, Cross- bred, Botany, Hosiery, etc. Although, fundamentally, the material to be treated is the deciding factor, it may be well in the first place to have in view particulars of typical sets of machines, from the study of which to obtain suggestions that ultimately may be reasoned back to the basic principles involved. The following problems—involved in the foregoing and succeeding particulars-are worth reasoning out carefully - 1. The relative numbers of boxes, spindles and heads to follow one another in any or every set of drawing; 2. The methods of feed for the several distinctive boxes ; 3. The sizes of bobbins ; 4. The relative output, floor space, power consump- tion, and cost of typical sets of machines; 5. The method of arrangement of a drawing and spinning shed, and of typical sets of machines. 271
