Abstract
An apparatus for gathering a textile fibre fleece from a doffer (3) of a card and forming therefrom a fibre sliver which is then fed to a conveyor (7) is disclosed. The apparatus includes a trough (8) which extends from a take-off location defined by a take-off roller (2). The trough (8) has width substantially corresponding to that of the take-off location and has a bottom (9) and sidewalls (10) which preferably converge in the shape of a funnel. The apparatus also includes a funnel disposed at one end (19) of the trough (8). The funnel is formed as a compressed-air-operable injector (11) for conveying and forming the sliver (5). End (19) of the trough (8) is connected to exhaustor means (23) which suck the fibre fleece (4) towards injector (11).
