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).

Abstract: Apparatus for separating waste particles from a textile fiber flow is disclosed which includes a housing (2, 22, 34) with a deviation zone (4) and separation zone (6). Following the deviation zone is a fiber flow discharge channel (5). Following a separation means (10, 11, 23) is a waste chamber (7) for removing large and small particles of waste. The waste particle separation device includes a plurality of rod elements (10, 11) which are curved to guide lighter particles upwardly to prevent adherence to the separating element. Larger particles pass through openings between the rod-like elements to the collection chamber. Communication between the fiber flow and the waste flow may be had by using a valve member (27, 35) to intermittently connect a collection channel (25) with a suction removal source (8) via waste chamber (7).

Abstract: A textile fiber preparation feed system and method are disclosed in which processed textile fibers from a blender (A) are delivered to a flow-through textile cleaner (B) and then directed to a vertical chute feed (C). An air stream conveys the fibers from blender (A) to chute feed (C) across cleaning rollers (34, 36) of cleaner (B) without a nip feed providing increased cleaning efficiency. Control system (60) continues operation of top feed roll (52) after termination of carding machine (14) and discharge of fiber batt (12) from the chute feed to purge excess fibers in the air stream. In this manner, accumulation of the excess fibers in a fiber column (F) above top feed roll is prevented which would block air exit (50) and choke down top feed roll (52) upon resumption of the carding machine or fiber batt discharge.

Abstract: A carding machine is provided with two doffer units. Each doffer unit comprises a doffer roller and an intermediate roller coordinated thereto, which rollers are shiftable into two different operating positions. In a first operating position, the intermediated roller is out of operation and the doffer roller works in a usual manner in combination with the main cylinder. In the second operating position the doffer roller is out of operational contact with the main cylinder and the intermediate roller, which has the same direction of rotation as the main cylinder, is positioned so as to transfer the fibers from the main cylinder to the doffer roller. The fiber fleeces leaving each of the doffer units may be combined to form a compound fiber fleece.

Each card machine (16) is fed by a vertical chute feed (18) to which a fiber delivery air flow is delivered from supply units (60, 62, 64). In this manner, a first fiber batt of uniform density across its width is fed to the cleaning machines. The fibers are more uniformly fed and separated to provide more uniform opening and cleaning of the fibers. The individual and cleaned fibers are fed to a vertical chute feed wherein a second fiber batt is formed for feeding to the textile cards.

A toothed disk is mounted on a shaft which extends transversely of the grid rods and is supported to rotate in the space between the grid rods. The toothed disk has a plurality of teeth extending at an angle from the plane in which its central portion lies so that the tips of adjacent teeth revolve in the space between the grid rods in a different orbital path.

Abstract: An apparatus for reducing pressed fiber bales arranged in a row is disclosed which facilitates removal of fibers from the upper surface of the bales adjacent a stationary member (28). Transversely extending rollers (18, 19) parallel to milling rollers (4, 5) are provided with blocking means (25, 26). These blocking means may be actuated to prevent rotation of rollers (18, 19). As rollers (18, 19) are carried by housing (2) so as to extend slightly beyond the housing in the direction of travel (16). Upon reaching stationary member (28), blocking means prevents rotation of roller (19). The teeth of roller (19) act as a rake to remove fibers from bale (24a) adjacent stationary member (28) as reducing means (1) starts its travel in the return direction. In this manner, the fibers from the entire upper surface of bale (24) are more totally and uniformly removed.
