There is disclosed a method of carding a fibrous feedstock to form a carded sliver using a carding engine (10) having a main toothed wire cylinder (11), a taker-in (12), a doffer (13), and a series of flats (14) movable along a closed loop (15) having a working path (16) arranged alongside the outer periphery of the cylinder (11) between the taker-in (12) and the doffer (13) in order to carry out a carding operation on the feedstock in cooperation with the teeth of the rotating cylinder (11) and to remove waste or trash particles and short fibres from the feedstock, in which the cylinder (11) is driven to run at normal production speed giving a circumferential speed Y of e.g. 60,000 inches per minute whereas the linear speed X of the flats (14) is a substantially increased speed compared to normal running speeds e.g. at least 16 incles per minute, thereby to produce a sliver with surprisingly improved quality which can approach that of a carded, and subsequently semi-coned (scratch-combed) or combed sliver. |
