- In the manufacture of wooden cloth the processes are many, but they are really simple. Briefly stated, they are as follows. The fibers of the wool are cleaned, straightened, and twisted into threads. These threads are put into looms, one set running lengthwise. Crosswise threads are shot between the lengthwise threads by shuttles. The 2 sets of threads are beaten together finally, and cloth is thus formed. When the wool comes to the factory it must first be sorted. This is to get the fibers of different lengths and qualities in the same groups. From these different groups different qualities of cloth will be woven. The wool is next scoured to clean it of its grease and dirt. The scoured wool goes to the carding machine which separates the fibers from each other. Then comes the combing which takes out the curl from the fibers and which also lays them parallel to each other. Then follows the drawing. This draws the layers out and combines them with other layers until at last the fibers become roving. Roving is a loose, thick thread which has little strength, because the fibers are merely laid side by side and scarcely twisted. The roving is twisted to the right size so that the fibers lie closely together. This gives them their strength. It is at this point that the process shown begins. As the yarn is spun it is wound on the bobbins that you see here. The bobbins that are intended to be used in the warp, or the lengthwise threads of the cloth, are sent to the dressing room to be placed on a loom ready for weaving. The yarn used for the cross threads, or weft, is wound on small bobbins and sent to the weft room. Trace one of the threads that is being wound on a bobbin.
