Elementary treatise on the finishing of white, dyed, and printed cotton goods . theoperation to stop the machine, to allow the clothto remain on the cylinders, until it is completelydry, as well as to straighten the selvages andguide the fabric, through the machine from enteringuntil it is batched. It is clear therefore that thismachine can only be used for completely solublethickening materials and that there can be noquestion of employing it for starches charged withinsoluble or mineral matters. This machine is principally employed whenthe cloth is to be softened by breaking the thicken-ing already deposited with the colours on the cloth,by the action of the steam, which, in evaporating,carries away with it, the last traces of acid, notremoved by steaming. This is the case in furni-ture styles with unwashed grounds such as arelargely manufactured in England. Fig. 19, page 120, represents a drying ma-chine similar to the preceding, but it worksmore rapidly. The arangement is for only onewidth of material and we have already noticed FINISHING IX (,KXKR \l. 120 B. FOLDOUT NOT DIGITIZED MACHINES EMPLOYED IN FINISHING. 121 a similar apparatus combined with a starch mangle fig. 11. Fig. 22, page 123, represents a similar ma-chine with 11 cylinders seen on the side of thesteam outlet. Drying machines, where the surface and backof the piece come alternatively in contact withthe cans are very good for ordinary and unweightedstyles. But it is evident that with this kind ofdrying machine, it is difficult to guide the pieceand there is the disadvantage of the great stretch-ing and tension of the cloth passing over somany cylinders. The fabric can lose as much as10% and even more of its original width, that isto say, its width before starching. For instance,with handkerchief styles, care is taken to stretchthem as little as possible and to widen them byhand as much as possible before the piece touchesthe first cylinder. We find this arrangement in machine shewnin fig. 20, page
