Fig. 332 exhibits a back view ofthis machine ; and fig. 333 a sec-tion of some of the parts not veryvisible in the former figure. Theback of the machine is the side atwhich the cotton is introduced be-tween the drawing rollers.

The cans, or lap-bobbins filledwith slivers at the drawing frame,are placed in the situation markedb, fig. 333, in rows parallel withthe length of the machine. Thesliver of each can, or the unitedslivers of two contiguous cans, areconducted upwards along the sur-face of a sloping board f, andthrough an iron staple or guide e,betwixt the usual triple pair ofdrawing rollers, the first of whichis indicated by a, b. In fig. 332,for the purpose of simplifying thefigure, the greater part of theserollers and their subordinate partsare omitted. . After the _ slivershave been sufficiently extendedand attenuated between the rollers,they proceed forwards, towards thespindles Hi, where they receivethe twist, and are wound upon thebobbins h. The machine defineated contains thirty spindles, butmany bobbin and fly frames con-tain double or even four times thatnumber. Only a few of the spindies are shown in fig. 332, for fearof confusing the drawing.
