But under any circumstances the hosiery spinner will do well to bear in mind the difficulties of knitting, and to supply the hosiery manu- facturer with the most perfectly spun and wound yarn possible. 4. For Export.—The fundamental problem here is the tare” account. The many costs incident upon exporting yarns on bobbins or spools practically rule out these methods of delivery. For the home trade the “Spool Counting by Weighing" machine of Messrs. Avery and Co., is strongly to be commended. The idea is to place the skep, paper, etc., on the platform of the machine and balance (recording the weight); then to fill the skep with spools and weigh these spools by making ten or twenty representative spools as the unit for weighing, the pointer indicating the number of spools in the skep. Fig. 91 is an illustration of this type of machine. While not quite as accurate as counting,” it is much more accurate than any es- timating,” even by experienced hands. Practically all the export trade is done in yarns directly spun on to paper tubes, or wound on to cheeses or in hank form. Again conditioning should be avoided if at all possible. 5. For Dyeing.–Yarns may be dyed on the following methods : (a) Hank dyeing; (6) Warp dyeing; (c) Cop dyeing; and (d) Cheese dyeing. For hank dyeing the yarn must be reeled into hanks 9 ( 310
