Abstract: A conveying unit of a textile machine has an endless circulating and drivable conveying element, the conveying element having a conveying area on an outer side thereof to receive and convey textile material. Opposite side walls are disposed to hold the textile material in the conveying area in a transverse direction of the conveying element. A sealing device is arranged between each of the side walls and the conveying element such that an interior space enclosed by the conveying element is at least partially sealed with respect to the textile material. The sealing device includes a sealing element connected to the conveying element so as to extend transversely away from and above the outer side of the conveying element.

Abstract: A fiber material storage device for a textile includes a storage chute having a chute housing and a supply line leading into the storage chamber. Fiber material is pneumatically conveyed with conveying air into the storage chamber. A cleaning unit in the storage chamber cleans contamination from the conveying air and includes a cleaning chamber. A semipermeable dividing wall is situated between the storage chamber and the cleaning chamber to retain the fiber material in the storage chamber and allow the contaminated conveying air to flow into the cleaning chamber. A filter element is situated in the conveying air flow between the cleaning chamber and outer surroundings to retain the contamination in the cleaning chamber and allow filtered conveying air to escape into the surroundings. The cleaning housing has a collection chamber situated underneath the cleaning chamber, wherein the contamination retained by the filter element settles in the collection chamber.

Abstract: A fiber conveyor for a fiber blending unit includes a blending belt, wherein fiber material dropped onto the blending belt from a bale opener is transportable away by the blending belt. Opposite guide walls are arranged laterally to the blending belt to guide the fiber material on both sides of the blending belt. A rotary distributor is arranged above the blending belt so that the fiber material dropped onto the blending belt is distributable in a transverse direction of the blending belt between the two guide walls by rotational movement of the rotary distributor.

Abstract: A pan scale for weighing and ejecting fiber components onto a mixing belt includes an upwardly open container having a plurality of side walls and a bottom formed by a single piece comprising a rotatably hinged bottom flap rotatable from a closing position abutting on one of the side walls into an open position folded away from such side wall, or two pieces comprising rotatably hinged bottom flaps that are rotatable away from one another from an inner closing position abutting against one another into an outer open position. The single bottom flap or at least one of the two bottom flaps includes a retaining device on a bottom surface thereof. Upon opening of the respective bottom flap, a part of the fiber components are retained in the container by the retaining device up to a partial opening angle (?) of the bottom flap.

Abstract: A fiber processing system for opening and mixing fiber material includes a plurality of bale openers for opening fiber bales. Conveying devices are arranged downstream of the bale openers for mixing and conveying the opened fiber material to a downstream processing device. The bale openers are divided into at least two opener groups, wherein each opener group produces a respective fiber mixture. Each opener group is allocated one or more of the conveying devices arranged in such a manner that the respective fiber mixtures are transported directly away from their associated opener group in different directions and the fiber mixtures are subsequently combined before or in the processing device into an overall fiber mixture.

Abstract: The invention relates to a fiber feed device (16) for a fiber blending unit (1) comprising a blending belt (15), by means of which fiber material (2) dropped onto the blending belt (15) from a bale opener (3) can be transported away, and comprising two guide walls (17, 18) arranged laterally to the blending belt (15) for guiding the fiber material (2) on both sides of the blending belt (15). According to the invention, the fiber feed device (16) comprises at least one rotary distributor (19) arranged over the blending belt (15), by means of which the fiber material (2) dropped onto the blending belt (15) can be distributed in the transverse direction of the blending belt (15) between the two guide walls (17, 18) by means of a rotational movement. The invention further relates to a fiber blending unit (1).

Abstract: The invention relates to a pan scale (1) for weighing and ejecting fiber components (32) onto a mixing belt (34) with an upwardly open container (2), comprising a multiple number of side walls (4, 5, 6, 7) and a bottom (9) divided into two parts in the longitudinal direction of the container, whereas the bottom (9) is formed by two rotatably hinged bottom flaps (10, 11), which can be rotated away from one another from an inner closing position abutting against one another into an outer open position. In accordance with the invention, the two bottom flaps (10, 11) are formed in a manner asymmetrical to one another, such that they feature bottom surfaces of different sizes (18, 19).

Abstract: The invention relates to a fiber processing system for opening and mixing fiber material, with a multiple number of bale openers (2) for opening fiber bales (FB) and conveying devices (4a, 4b; 14a, 14b) downstream of the bale openers (2) for mixing and conveying the opened fiber material to a downstream processing device (10), for example a mixing chamber or a carding feed.

Abstract: A method and a device for opening and dosing fiber feeds the fiber material via a feeding shaft of an opening device. The fiber material is processed in a first opening step of a dosing opener and is fed without an interconnecting pneumatic means to the feeding shaft of a second opening step. A large-volume feeding shaft has been placed before the first opening device from which the fiber material is delivered to a feeding shaft with a considerably smaller volume that delivers the fiber material to a second opening device. Both opening devices and their associated feeding shafts are placed on top of one other.

Abstract: Method of and apparatus for bundling fibers of a sliver in the drafting frame of a spinning machine in which a fiber-bundling zone is provided downstream of the last pair of drafting rollers. The fiber-bundling zone can be formed with a transporter for the sliver, e.g. a belt, provided with an array of perforations having a width which is at least equal to the traversing width of the sliver. The suction orifice juxtaposed with the array of perforations of the belt is inclined to the direction of the travel of the sliver and preferably extends over the full width of the traversing motion. The edge of the orifice can be rectilinear or curved.
