Carder for manufacturing non-woven formed fabric from fibrous substances comprising a plurality of principal rollers and workers and clearers working with said principal rollers, comprising a draw-in roller (1) and a licker-in (2) running in the same direction and with high drawing, comprising a first principal roller (3) running in a direction opposite the licker-in (2) and with low drawing, comprising at least one pair of rollers consisting of a worker (4) and a clearer (5) cooperating with said first principal roller (3), and comprising a first matting roller (8) running in the same direction as said first principal roller (3) and with low crushing or with low drawing, whereby the draw-in roller (1), the licker-in (2), the principal rollers (3, 9), the matting rollers (8, 12), the doffing cylinders (13, 18) and the second crushing cylinders (15, 20) are driven by respectively separate, independently controllable motors such that a change of the speed of the principal roller (3) effects a change of the speed of all other rollers (FIG. 1).
In an improved carder for fleece manufacture from fibrous material comprising at least one draw-in roller, a licker-in roller running oppositely to said draw-in roller, at least one master roller, and including worker roller means and clearer roller means cooperating therewith, the improvement wherein each master roller is followed by a fleece matting means, each fleece matting means comprising a matting roller means running in the same direction as the associated said master roller, said matting roller means producing a fleece drawing between 1 and 2 times compared to the associated said master roller a fleece draw-in depression cooperatively formed with said draw-in roller, whereby a fleece drawing of from about 100 and 200 times is provided between said draw-in roller and said licker-in roller with said licker-in roller running in the same direction;
