<p>A method and apparatus (10) for forming a sliver (30) from a fibrous web (18) leaving a carding machine and comprising: a cooperating pair of control rollers (13, 14) arranged one above the other to receive the fibrous web (18) issuing from a doffer (12); a condenser arrangement (15) downstream of the control rollers (13, 14) and comprising a cooperating pair of endless conveyor belts (16, 17) which extend generally lengthwise of the rollers (13, 14) and define a nip N located intermediate the ends of the control rollers (13, 14) which receives and condenses the web (18); and sliver-forming means (19) arranged downstream of the nip N in which the endless conveyor belts (16, 17) comprise: a) web-guiding runs (22, 23) which face the control rollers (13, 14) and which guide and condense the web (18) towards the nip N; b) return ends (24, 25); and c) rotatable return ends (26, 27) at the ends of each conveyor belt (16, 17) which have an axis of rotation (29) which extends obliquely upwards and towards the sliver-forming means (19), to provide improved gripping and guidance of the condensed web (18a) which is fed to the sliver-forming means (19).</p> |
