Filed: 1962-12-12
Abstract: 964,479. Carding engines. E. SHAPIRO. Dec. 12, 1962, No. 46963/62. Headings DID and D1N. A carding machine having a card-clothed cylinder rotatable within a close-fitting cover has the clothing teeth formed with their forward edges disposed radially of the cylinder. Fibre lap is fed between feed rolls 21, 22 to a first cylinder 15 shrouded by a cover 38 and the fibres treated by the cylinder 15 are thrown on to the teeth of the cylinder 16 which rotate at a greater, e.g. twice, peripheral speed in the same direction. Fibres are dragged around the edge of the cover which protrudes into the zone between the two rollers and where an air space is arranged in order to facilitate the change of direction of the fibres about the edge. Although not essential, high speed clearer rollers 27, 28 may be provided to eliminate any possibility of fibres accumulating in the teeth of the cylinders 15, 16. The clearance between the teeth of the cylinders and their covers may be about 0. 015 inch. Because a carding effect is obtained by fibres dragging on the inner surfaces of the covers, these surfaces may have a slight roughness imparted to them, as by sandblasting. Transfer of fibres from cylinder to cylinder is facilitated by the configurations of the teeth employed which are as indicated in Figs. 7a to 7g. Cylinder 15 and doffer 31 are adjustable relative to the cylinder 16 by manual movement of wedge-plates. Lateral adjustment of cylinders is also provided to affect clearances with respect to end cowls, such clearances being of the order of 0. 005 inch. As shown the carding elements are vertically aligned and it is preferred to mount machines in pairs, back to back on a common frame. An electric motor 100, Fig. 11, may be mounted on the frame for driving the carding elements through belts, with a worm drive 114, 115 to the feed rolls 21, 22. The doffer 31 may be independently driven from a motor 111. A machine utilizing flats is described with reference to Fig. 12 that has three carding cylinders 150, 152, 154, clearer rolls 177, 178 and flats 156. The carding cylinders are adjustable relative to each other and their bearing blocks are held in adjusted position under spring loading to allow movement in the event of foreign bodies being encountered. It is stated that, in lieu of flats, other means may be utilized for providing a confining surface which is rough for accentuating the carding action, and that the vertical positioning of the elements may be reversed so that sliver issuing from the machine may readily be fed into a can. A stop motion is provided to operate if the feed rolls are pushed back for any reason.
