Abstract
The card for producing a fiber includes a swift and a doffer which takes the carded fibers off the swift and supplies them to a nip formed between at least two rotating rollers. The fiber web emerging from the nip is deposited on the top run of a transverse conveyor which moves axially of the rolls between guide rollers in order to convey the fiber web laterally away from the card. The conveyor has a shoulder on at least one longitudinal side against which the fiber web may abut during travel along the transverse conveyor.
