Apparatus for automatically starting formation of sliver from a carded

Abstract

An automatic startup device in a carding machine includes a roll assembly for discharging the fiber web; and a web transporting arrangement situated under the roll assembly for gathering and advancing the web. The web transporting arrangement is formed of two adjoining, driven endless belts which together define a gap through which the web is discharged downwardly. The two endless belts or portions thereof are simultaneously shiftable horizontally to cause the web discharge gap to assume first and second locations spaced horizontaly from one another. There is further provided a trumpet situated under the web gathering belts. The trumpet has separable parts between which the web is introduced from the web discharge gap. In a separated 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 joined 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. The trumpet, or parts thereof are moveable horizontally, so that the trumpet inlet is situated substantially vertically underneath the shiftable discharge gap in both of its locations. There are further provided a web delivery arrangement which is underneath the trumpet outlet when the web discharge gap is in its first location and a calender roll pair which is underneath the trumpet outlet when the web discharge gap is in its second location.
