the wool on the burr, d, into an iron box, g, from whencethey are removed at intervals. The transfer of the wool fromthe burr roller to the cylinder is effected by the first stripperroller, W \ under which is placed a fly roller, //, for the purposeof catching up any dropped fibres and preventing their fallingto the ground. The Intermediate Card. As a glance at the five-roller intermediate card in Fig.219 will show, this machine differs from the scribbler in noimportant particular. The weighed lap spread by hand onthe lattice feed creeper, a, is seized by the feed rollers, b, c,and—there being no burr roller-—is presented direct to thecylinder, T, which, with its assistant rollers, disposed in theusual manner, repeats the carding operation, with whichobject they are all covered with a finer count of card clothing. The full-width fleece, removed by the doffer comb, d,passes under the guide and compression roller, e, to theMartin lap former, where it is converted into a lap of man\

When the lap has attained the requisitethickness it is torn off at / in a direction parallel to the longi-tudinal axis of the roller, and is wound on a wooden bobbin,k, supported on the inclined arms, /, to form a bobbin of lap,;;/. The wooden bobbin revolves by contact with the canvasband: and, as the diameter of the wound lap increases, thebobbin is able to move away freely in its bearings. The Finisher Card. This final member of the carding set is identical with theintermediate card, except that the card clothing is finer andthat the resulting fleece is no longer formed into a lap, but isdelivered direct to the divider or condensing mac
