Abstract
A device for condensing a fleece emerging from a carding engine or a like machine has two adjoining and aligned sets of rollers (5, 5', 5', 5'') having hollows along their generating lines and which are rotated about their own axes perpendicularly to the plane at which the fleece is doffed, and which are spaced apart relative to a fleece doffing roller (3). The rollers belonging to a set rotate in a direction and those of the adjoining set are rotated in the sense opposite to the former. The rotation of the rollers of two adjoining sets can be concordant in direction so as to provide a central doffing spot (13) between the two sets, or such a rotation can take place in directions opposite to one another and diverging, so as to provide two doffing spots (13,13') placed laterally of the two roller sets. By the rotation of such rollers two airstreams are originated, whereby the fleece is airborne and so conveyed towards the doffing spot(s) where a fibre sliver is formed to be forwarded to a condensing unit.
