In a nonwoven card for the production of nonwoven fabric of fiber material, with a drawing-in means (2,4), a licker-in (6), a main cylinder (16), and at least one fiber doffer means (18) engaged with the main cylinder (16), for doffing a card web, the drawing-in means (2,4) transferring the fiber material to the licker-in (6) and a transfer means (8) transferring the fiber material at least double from the licker-in (6) to the main cylinder (16) via rollers (10, 10a, 10b, 10c, 12, 12a, 12b, 14), it is provided that at least one of the rollers (10, 10a, 10b, 10c, 12, 12a, 12b, 14) of the transfer means (8) is a random roller (10, 10a, 10b, 10c) rotating in the same direction as the main cylinder (16) and the licker-in (6).
A nonwoven card for the production of nonwoven fabric of fiber material comprising a drawing-in means (2,4) in the form of rotating drawing-in (2) and taker-in (4) rollers, a licker-in roller (6) rotating oppositely to the rotation of said taker-in roller (4), a main cylinder (16), at least one fiber doffer means (18) engaged with the main cylinder (16) for doffing a fibrous web, the drawing-in means (2,4) transferring the fiber material to the licker-in roller (6) and transfer means (8) for transferring the fiber material from the licker-in roller (6) to the main cylinder (16) along two different transfer paths of travel via a plurality of transferring rollers (10, 10a, 10b, 10c, 12, 12a, 12b, 14), characterized in that at least one of the transferring rollers (10, 10a, 10b, 10c, 12, 12a, 12b, 14) of the transfer means (8) is a random roller (10, 10a, 10b, 10c) rotating in the same direction as the main cylinder (16) and the licker-in roller (6).
A method of producing nonwoven fabric of fiber material by means of a nonwoven card by supplying the fiber material via a rotating drawing-in roller (2) to an oppositely rotating taker-in roller (4) to a licker-in roller (6), by transferring the fiber material from the licker-in (6) to a main cylinder (16) for carding the fiber material, and by doffing at least one fibrous web from the main cylinder (16), characterized by the step of transferring the fiber material along two different transfer paths from the licker-in (6) to the main cylinder (16) by using at least one random roller (10, 10a, 10b, 10c) on at least one of the two different transfer paths.
