Here itwill be seen the rack is of a different construction, and iscarried upon bowls in order to diminish the power neededto actuate it. The variation of the movement requiredfor the traverse is also obtained in a simpler way thanas shown before, being got from a slight eccentricityin the mount of the pinion driving the rack. This eccen-. Fig 154. tricity is so small as not to be discoverable in the illus-tration. The above types of machines are in almost general usethroughout the great weaving districts of North-eastLancashire, and in others where similar plain goods aremanufactured, or such fancy goods as do not need anypreliminary treatment, such as bleaching or dyeing of theyarn previously to its being woven. In many places, however, what is called the colouredgoods trade is the staple industry. This prevails inRochdale, Heywood, Radcliffe, Farnworth, Swinton, New-ton Heath, Failsworth, and a few other smaller places. In 264 COTTON WEAVING. these a large proportion of the yarns used, both warp andweft, have to be bleached or dyed, mostly the latter,before the weaving process. In these cases the windingprocess is changed for what is termed reeling. The yarn,instead of being wound upon bobbins from the cops orring bobbins, is wound upon reels, and when doffe
