  • Patent number: 4852217
    Abstract: A carder for manufacturing non-woven materials from fibrous material which includes at least one draw-in roller, and a licker-in roller following the draw-in roller and rotating in the same direction. There are at least two worker rollers of the same diameter following the licker-in roller, the two worker rollers rotating in the same direction and at a greater speed than the licker-in roller. At least one doffing cylinder cooperates with the last of the worker rollers. Further worker rollers follow the two worker rollers, with the various worker rollers being separated by transfer regions between adjacent rollers. The relative speeds and the spacings between adjacent rollers are adjustable to control the proportion of fibrous material that can be returned to previous worker rollers or sent to succeeding worker rollers. An air-guiding box projects into at least one of the transfer regions, the box being adjustable in height and width.

  • Patent number: 4523350
    Abstract: 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 spee
