Almost all cotton comes to the mill in standard compress bales of five hundred pounds gross. The cotton is condensed to about 22 pounds per cubic foot at the compress, wrapped in coarse jute bagging, and circled with iron hoops. For some time there has been a movement to improve the so-called square bale, or to replace it with a different form of packing. Sea Island cotton is frequently packed in a smaller round bale, and there is much to be said for this practice. What we are concerned with here, however, is that the mill receives the cotton in a compressed form which must be loosened before anything can be done with it. [Sidenote: THE BALE-BREAKER] Accordingly, the first thing that happens is that the hoops are cut, the bagging removed, and the cotton thrown by hand into the feed-apron of the bale-breaker. This machine does nothing more than to pick the compressed cotton apart and deliver it in tufts about the size of a handfull on a belt conveyor. [Sidenote: _The Opener_] The travelling belt or feeder delivers these bunches of cotton into machines called Openers, which simply repeat the operation of the bale-breaker on a more thorough scale, reducing the large tufts into many smaller ones. These small pieces are dropped into an air chute and drawn along parallel rods up to the picker room. During transit in the trunk much of the heavier dirt falls between the rods and is removed. In the most recent installations larger bale-breakers are used which reduce the cotton to small tufts and deliver through an air pipe to a condenser in the picker-room. The condenser either empties into bins or else on to the automatic feed of the breaker-pickers. [Illustration: _Bale Breakers_] [Sidenote: _Pickers Remove Coarse Dirt_] As the tufts come out of the chute they fall into the first of three machines known as Pickers, whose function is to beat out the coarser impurities and deliver the cotton in rolls of batting called laps. In the first, or breaker-picker the tufts are thoroughly whirled and pounded over grid-bars by rollers armed with short flail-like projections, and then compressed into a continuous sheet or lap of a given weight per yard, which is wound on a large spool and delivered to the second, or intermediate picker. This machine practically repeats the operation only that it combines four laps from the first picker into one which it hands over to the last, or finisher picker. The latter again takes four intermediate laps and forms them into one sheet of fairly clean cotton, containing very little dirt or seed, but still fairly filled with small particles of leaf. In these preliminary operations the cotton has lost about five per cent. of its weight. [Illustration: _Picker Room_] [Sidenote: _The Function of the Card_]
