Again, the question of winding or not may depend upon the type of loom -or rather upon the type of “pick" and the length of shuttle-box. With a hard pick and a short shuttle- box it is impossible to prevent softly wound spools from “sluffing," i.e. the yarn shooting off the end of the bobbin as the shuttle is brought too suddenly to rest. This difficulty, however, would not arise with good spinning, a slinging ” pick, and a long shuttle-box and checking arrangement to bring the shuttle slowly to rest. 3. For Hosiery or Knitting Machines.—Tests carried out to decide the relative merits of the different systems of drawing and spinning for hosiery yarns have shown- (a) that there does seem to be an advantage of fullness in French or twistless drawing; and (6) that there is little or no difference between mule, flyer (special construction) and ring spinning. Yet hosiery manufacturers still incline to the mule- spun yarn. The probable reasons for this are- (1) Less loss in oil, the yarns being “dry" spun. (2) Sometimes more perfect workmanship, and (3) A greater length spun without a joining. The dire results of knots, slubs and bad places in yarn during the actual knitting operation need not be elaborated upon—they are self-evident. It will, there- fore, pay the hosiery yarn spinner to spin his yarns as perfectly as possible, and then to wind on to the conical- shaped cheese of large diameter so strongly favoured in the hosiery industry. Many hosiery manufacturers regard the perfect building up of the cheeses they use on to > ale Hoon . me. army 404 L. 309
