The cones may be forced together so hard that 24 KNITTING. 15 the leather friction band will not transmit the power it shouldwith proper tension. Too much pressure will make the winderrun hard and cause trouble with the winding and is entirely un-necessary. One edge of the leather friction band should not beallowed to stretch more than the other and will not if the conesare kept the same distance apart at each end. This distance maybe adjusted by means of check nuts just beneath the bearings ateach end of the shaft on the lower or driven cone. If the abovedirections are followed carefully the cone drive will help thewinder to build a more evenly uniform bobbin and build itquicker with less breaking of the yarn in the Old Type of Knitting Table. 16 KNITTING. KNITTING YARN TABLES AND CALCULATIONS. The methods of designating the weight of mule spun yarnvaries in different localities. The custom in the Cohoes Mills is todesignate the yarn by the weight in grains of three threads fromone draw of the jack; that is, after the jack has run back anddrawn the roving off the spools, spun it and run to the further-most point from the drawing roll, which is about 6 feet 3 inches,take three threads (from the spindle to tlie drawing rolls) breakthem off, and weigh them together. The weight in grains ofthese three threads, about 6] yards in length, is the grain of theyarn. For instance, if these three threads weigh 111 grains, tlieyarn is classified as Hi grain yarn. The Amsterdam method is to take 6 draws. This gives acloser
