Abstract
Conditions relating to the balanced operation of a jute processing system are considered. Modern systems evince a considerable degree of inflexibility in the choice of suitable system parameters, and equations are formed relating spyndle weights, mass proportions, number of spindles, efficiency and spinning speed for the composite system required to overcome this inflexibility. The older type of system is shown to possess a greater degree of flexibility, in that the second and third drawing draft may be varied in any manner consistent with their draft product remaining constant. Conditions determining the most economical use of machines are derived, leading to an evaluation of the saving in number of machines, at different efficiency levels, as the draft is reduced. A flow analysis of systems recommended by machinery makers is performed, illustrating factors governing machine efficiencies. The system of a mill employing old machinery is analysed. Although the text is concerned primarily with a jute processing system, it will be evident that the principles enumerated apply to any textile process, or indeed to any successional system whatsoever.
