The trumpet has separable parts between which the web in introduced. In a first position the two trumpet parts are at a relatively large distance from one another, whereby the web is discharged by the trumpet in a substantially unaltered state and in a second position the two trumpet parts are at a relatively small distance from one another, whereby the web is compressed and discharged by the trumpet as a sliver. There are further provided a web delivery arrangement under the trumpet for receiving and removing the web; and a calender roll pair arranged under the trumpet for receiving and advancing the sliver discharged by the trumpet.
