These confine the action of the air draught to theback of the cages. After leaving the vStripping rolls, the cotton, now in acontinuous but thick sheet, passes along a plate and then between twoheavy calender rolls, around the front of the lower one, between it and a.

It is then carried over a large fluted roll to a secondsimilar one. Between these two, on the top of the sheet of cotton, an ironrod is placed. About this the cotton is trained, and the revolution of thelarge fluted rolls keeps the mass in motion and rolls it up. In order to PREPARATORY PROCESSES AND MACHINES 25 make the lap tightly compressed so that much msLj be put into little space,a weighing device is applied which will soon be described. The calenderrolls, heavy of themselves, and additionally weighted by levers andweights, make the sheet of cotton quite thin; but the elasticity of thecotton would make the lap expand unless it were formed under 20 and 21 show the lap-forming mechanism at the front of themachine. The sheet of cotton can be seen passing between the two lowest cal-ender rolls, and its
