Example : Required spindles in reducing-box to follow 2.9 spindles in the 2nd drawing-box ? 29 x 30 x 6 x 6 x 6 - 56 spindles in reducing-box to 14 X 4 X 3 X 2 follow 2.9 spindles in and drawing-box. Over-all measurements and the weights of the re- spective flyers should be taken into account, as well as the empty and full weight of the bobbins and the relative leverage between nozzle and bobbin surface empty and full. Thus it is evident that here are many most interesting problems. It is, however, the textile engineer's job to face these problems : some have already been faced and the difficulties surmounted, but it is possible that even the cursory glance at drawing and spinning machinery taken in this book may prove useful to those engineers who are determined to act on the principle that "that which is not best is wrong.
