摘要： The invention relates to a device (1) for individualizing fibers of a supplied fiber sliver end and to a spinning device (2) comprising such a device (1). The device (1) comprises a first hollow body section, to which pressure can be applied and which comprises an inlet channel segment (3) for receiving and guiding a supplied fiber sliver end together with a fluid in the direction of an unraveling channel segment (6) arranged downstream thereof, and the unraveling channel segment (6), which communicates with the inlet channel segment (3) and is arranged downstream thereof, for unraveling the fiber sliver end supplied together with the fluid into individual fibers. The unraveling channel segment (6) forms an annular channel (10) which communicates with the inlet channel segment (3). The annular channel (10) has a channel inlet (11) with a first passage width and a channel outlet (12) at a distance therefrom with a second passage width, wherein in a section extending from the first passage width to a central passage width of a channel center arranged between the channel inlet (11) and the channel outlet (12), the passage width of the annular channel (10) tapers constantly or in sections such that the central passage width is smaller than the first passage width.

摘要： In pneumatic feeding of fibers (20) to the fiber collection surface of an open-end spinning element, the air which circles together with the opener roller (10) and is conveyed past the inlet opening (40) of the fiber feeding channel (4) is fed back to the fiber feeding channel (4). In this process, the air is conveyed in the circumferential area of the housing (1) between the inlet opening (40) of the fiber feeding channel (4) and the feeding point (21) of the fiber sliver (2) to the opener roller (10) to at least one end of the opener roller (10) and is then fed back along this (at least one) end of the opener roller (10) to the inlet area of the fiber feeding channel (4). Here the air duct, by comparison with the distance between the end wall of the opener roller (10) and the end wall of the housing (1) facing it in the area which does not serve as air duct as seen in the direction of fiber conveying - is designed as an enlargement of the distance between these end walls between the opening (13) containing the feeding device (3) at least in part and the inlet opening (40) of the fiber feeding channel. It extends from the opening (13) containing the feeding device (3) at least in part to the area of the inlet opening (40) of the fiber feeding channel (4).

摘要： In order to make the start-up of spinning easier and to obtain a spinning triangular zone which is easily accessible and easily observed, the feeding in of fibers is provided at a rear triangular zone 35 whereas the twisted spun yarn 6 is withdrawn from the other triangular zone 36 in parallel to the plane 34 of the closest distance between the two spinning members 1, 2. The fibers have to pass a narrow section, since the triangular zone 36 is disposed oppositely to the triangular zone 35 versus the line of adjacency of the two spinning members. Suction openings 3' 4' of the suction provisions 3, 4 are directed toward that triangular zone 36 from which the spun yarn is withdrawn. The fiber input location 5' of the fiber feed provision 5 is directed toward the surface of that spinning member 1 whose surface 32 moves in the direction of the first triangular zone 35.

摘要： The invention refers to a spinning unit of an air jet spinning machine with a spinning nozzle (1) used to manufacture yarn (2) from a fiber strand (3) fed to the spinning nozzle (1), in which case the spinning nozzle (1) has an inlet (4) for the fiber strand (3), a swirl chamber (5) located inside, a yarn forming element (6) protruding into the swirl chamber (5) and a exhaust duct (24) for the yarn (2) as well as an outlet (7) for the yarn (2) produced in the interior of the spinning nozzle (1). According to the invention, it is suggested that an additive supply (8) be assigned to the spinning nozzle (1) designed so the spinning nozzle (1) is supplied with an additive, in which case the yarn forming element (6) has at least one additive duct (10) that ends in the swirl chamber (5) or exhaust duct (24), and in which case the additive supply (8) encompasses at least one additive supply line (14) connected fluidically to the additive duct (10) so that an additive introduced into the additive duct (10) via the additive supply line (14) can be introduced into the exhaust duct (24) and/or swirl chamber (5). In addition, a process for operating an air jet spinning machine with at least one spinning unit is suggested, in which case an additive is added, at least intermittently, to the spinning nozzle (1) of the spinning unit while it is operating with the help of an additive supply (8), and in which case the added additive is delivered through an additive duct (10) of the yarn forming element (6) to the exhaust duct (24) and/or swirl chamber (5).

摘要： A fiber control apparatus in an open-end spinning frame is disclosed. According to the invention, in an open-end spinning unit having a fiber passage through which fibers opened by the combing roller are carried into the spinning chamber of the rotor, one or more nozzles are provided in the unit, each nozzle having an outlet opening located adjacent to the fiber outlet opening of the fiber passage so that one or more streams of jet air, emitted from the nozzle or nozzles, direct and guide the fibers introduced into the chamber toward the interior peripheral surface of the spinning chamber of the rotor, thus causing the fibers to reach said surface immediately without being slowed or bent by ambient air streams within the chamber. Consequently, formation of yarn having bent or randomly attached fibers is substantially prevented, whereby the strength and quality of the spun yarn is greatly improved.
