Abstract
A fiber sliver producing apparatus includes an arrangement for making a running fiber web; a transverse web gathering device gathering the fiber web; and a sliver trumpet through which the gathered fiber web passes for being densified and discharged thereby as a running sliver. The sliver trumpet has a cross-sectionally rectangular outlet opening which has a width that is at least 10 times greater than its height. The apparatus further has a calender roll pair formed of two calender rolls through which the sliver passes after being discharged by the sliver trumpet. The calender roll pair defines a bight in which the outlet opening of the sliver trumpet is disposed.
