Filed: 1952-08-07
Abstract: 731,077. Carding machines. STEARNS & FOSTER CO. Aug. 7, 1952. No. 19903/52. Class 120(1). A carding machine has a carding cylinder rotated at a speed high enough to induce a counterflow of air between the cylinder periphery and a baffle so that the fibres are discharged from the clothing of the cylinder by the counterflow of air. A lap of fibres may be fed onto a carding cylinder 1 by a feed roller 4 in co-operation with a feed bar 7. Stripper and worker rollers 10, 11 rotate in association with the cylinder 1 and may be of 3 in. diameter and rotate at 60 and 15 r.p.m. respectively, the cylinder being of 12 in. diameter and rotating at 1,800 r.p.m. Part of the air current created by the high speed of the cylinder 1 strikes a baflle 13 and is deflected to pass through the clothing on the cylinder, thereby removing from the cylinder those fibres not thrown off by centrifugal action. Fibres then accumulate on a foraminous drum 15 from which they are discharged in the form of a lap 21. Instead of the drum 15, the fibres may be thrown onto a travelling belt. Specification 632,226 is referred to.
