The SCUTCHER, which has also a lap machine combined with it (fig- 4), in many respects resembles the opener. In some cases it is fed with cotton in a loose fleece, and in others, instead of the loose cotton, three or four laps aro placed upon the feeder, and the beater or beaters are used in place of the cylinder. The cotton is further cleaned PIG. 7. Combing Machine. and carried forward in the same manner as in the opener making laps for the second or finishing scutcher, which is of similar construction to the first, the laps going from this machine to the carding engine. The CAKDING ENGINE (figs. 5 and 6) consists of one large or main cylinder covered with cards, a smaller one called the do/er, and a still smaller one called the taker in. The main cylinder is surmounted with small ones, called rollers, covered in like manner with cards, by whose revolu tions in opposite directions to those of the large cylinder, and with different velocities, the cotton is carded and r .. on the second cylinder or defer. In some cases the main cylinder is furnished with what are technically termed ats a series of flat cards revolving to form an endless travelling lattice. The third cylinder, or taker in, which is really the first to act upon the cotton, is usually FIG. 8.

The cotton is taken the doffer in a very light fleece by means of a vibrat comb, and this fleece is drawn together into a iunne
