Abstract
An apparatus includes a carding machine which has a web trumpet gathering a running fiber web into sliver and a calender roll pair arranged immediately downstream of the web trumpet for pulling the sliver therethrough. The apparatus further includes a sliver coiler having a rotary coiler head through which the sliver passes and a first sliver trumpet having an inlet which constitutes the inlet opening for the coiler head. A sliver drawing unit is arranged at the inlet opening for the coiler head for drawing the sliver running therethrough prior to entering the coiler head. Further, a second sliver trumpet is arranged at the inlet end of the drawing unit for guiding the sliver thereto.
