Sliver-forming device in a fiber processing machine

摘要

A fiber processing machine includes an arrangement for producing a running fiber web having a width extending perpendicularly to the running direction; a roll unit having a roll axis and a roll surface engaging the running web; a web guiding element disposed downstream of the roll unit for laterally gathering the web for reducing the width thereof; and a web trumpet disposed downstream of the web guiding element. The web trumpet has an outlet opening for discharging the running web. The outlet opening has an outlet height and an outlet width greater than the outlet height. The outlet width is oriented to the roll axis at an angle other than zero for reorienting the width of the web during run thereof from the roll unit to the outlet opening. A calender roll pair is disposed downstream of the web trumpet.
