Abstract
In order to control cotton fibre fluctuation between the compactor device (5) and the drafting unit (6) within a card (1A), the drafting unit (6) can be moved (either along a rectilinear trajectory and/or along a circular trajectory) between a first position (L) coinciding with its maximum distance from the compactor device (5) and a second position coinciding with its minimum distance from said compactor device (5) until said distance is reduced to the minimum possible. The distance between the drafting unit (6) and the compactor device (5) varies in a manner inversely proportional to the operating speed of the card (1A). In an alternative embodiment: a support and guide element (40) for the web (9) is positioned between the doffer (2) and the pair of rollers (7, 8) of the compactor device (5); a conveyor device (24) is interposed between the compactor device (5) and the drafting unit (6) (FIG. 2).
