Abstract:
A flat card in which the main card drum (10) is fed with a number of batches of fibers (A, B, . . . , H, L) by means of a plurality of feed devices (20A, . . . , 20L) comprising taker-in rollers or licker-in rollers (8A, . . . , 8L), which operate in parallel to feed, upstream of moving flats and in different points of the main carding drum (10), the fibers which they have already roughly spread and purified in a layer that adheres to clothing of each licker-in roller (8A, . . . , 8L), characterized in that the feed points with the various licker-in rollers (8A, . . . , 8L) are set in sequence and staggered according to angles (&agr;AB, . . . , &agr;HL) for an overall arc of circle of amplitude (&agr;AB, . . . ,&agr;HL), in such a way as to constitute a series of pre-carding areas that are specific for each batch fed in according to the succession of batches of fibers (A, . . . , L), and in that each licker-in and each pre-carding area is provided with equipment that can be specifically regulated and adapted for each batch of fibers that is being processed.
