The twisting spindles will usually be decided by the rule Spinning spindles Ends folded together Twisting spindles. Sometimes owing to the superior speed of twisting spindles fewer may be required to follow the spinning. In flyer spinning, for example, followed by ring twisting the spindle speeds must be taken into account; thus- Spinning spindles x Spinning spindle speed Ends folded x Twisting spindle speed Approximate Twisting spindles required. The output of a set of drawing and spinning similar to the foregoing may readily be obtained from the foregoing particulars with allowances which should be actually ascertained for each set in each mill. The following may be taken as questionable bases :- Count] To's 15's 20's 30's 40's 50's 60's Efficiency 70 72 74 76 78 80 82 The calculation-based on the spinning of the Botany standard yarn, viz., 48's—will stand- a (yd. per min.) x 60 x 16 x 82 = b oz. per hour per 48 x 560 X 100 spindle. Thus for the full set of drawing and spinning for one hour the production could be- Xc (spindles) x 48 16 (oz. per lb.) d lb. per spindle per week. sobie 02 1 283
