Abstract: Apparatus for cleaning textile fibers such as cotton, etc. is disclosed wherein the fibers are conveyed by an air current to an opening roller cooperating with a grate, and the transport air is separated at a feed box. The separated air (17) serves for discharging contaminants accumulating in a space (9, 11) beneath the cleaning grate (8). The opening roller (7) may be provided with a toothed wire (20) whose teeth have a relatively acute top rake (22).

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).

Abstract: The apparatus acts on a textile fiber band or sliver (2) wound in a sliver can (3) to form primary coils helically aligned about the axis of said can to form superposed secondary coils. A grasping member (2) movable in a vertical direction raises some of said primary coils (4). A supporting member (17) is then moved close to one sliver length (28) descending from the raised coils (4) to arrange said length so that it may be disposed astride of the supporting member itself when said coils (4) are dropped into the can (3). Sliver (2) as a result of the rotation of the supporting roller (20) or as a result of the rotation of the supporting roller (17) to bring the free end (2a) of said sliver close to the supporting member (17). The free end (2a) is engaged between the feed rollers (10, 11) of a textile machine by moving the supporting roller (17) close to said feed rollers or by moving the feed rollers close to each other.
