| SORTING RAW WOOL INTO GRADES. We now follow the wool into the factory. There are two grading processes through which the raw wool passes before being spun into yarn. The first is the sorting of the wool as shown in the picture. This may be termed a grading for quality. The second process is the combing, which may be termed a grading for fiber length. Wool comes to market in fleeces, just as it is sheared from the sheep.

CARDING MACHINE. Carding the wool, formerly done by hand, is now accomplished by machinery, the carding machine consisting of a series of rollers which are covered with teeth. The rollers are of different sizes, set at different distances and revolving at different speeds. The raw wool is fed into the machine at one end, and by action of the rollers the fiber is combed and straightened and finally delivered in the form of a fluffy woolen rope, which you see coming out of the front end of the machine.

| SPINNER. Here we have a view of a spinning room. The carded rolls are here spun into threads, which are later woven into cloth or twisted into yarn, as desired. In the various improvements of spinning machinery, the object has been to invent devices for working a large group of spindles together and running them at a very high speed.

|
TWISTER. This machine is called a twister and here the threads are drawn from the carded rolls and are twisted into yarn. Twisting is a part of the spinning process proper, which, in making worsteds, consists in first drawing out or drafting; second, twisting the drawn-out fibers; and third, winding the fibers, now called yarn, on the bobbin.
