摘要： A spinning unit of an open-end spinning machine comprising a spinning rotor to which separated fibers are supplied to be formed into a yarn which is withdrawn through a take-off duct and wound onto a bobbin. At its inlet end portion, the yarn take-off duct is rounded and embodied as an exchangeable funnel around which the yarn sweeps while it is given a false twist. In accordance with the invention the funnel and the body of the yarn take-off duct constitute a pair of members, the funnel being coupled with the body of said duct by magnetic coupling means so that funnels may readily be changed in accordance with the requirements of various fibrous materials to be processed by the spinning unit.

摘要： Open-end spinning unit having two housings connected to each other, a first housing containing a spinning rotor adapted to be supplied through a supply duct with separated fibers carried by an air stream while yarn is withdrawn therefrom through a take-off duct, the second housing containing a sliver supply roller and a combing-out cylinder followed by said fiber supply duct extending through a lid inserted into the spinning rotor and forming a part of said second housing, the spinning rotor being surrounded with an air collecting space adapted to collect the air to be withdrawn from the spinning rotor. The spinning rotor turns about a vertical axis of rotation and is driven by an individual motor through the axis of which the yarn take-off duct extends in an upward direction. The lower front part of the spinning rotor extends into a cavity provided in the top part of said second housing. The combing-out cylinder and the sliver supply roller have horizontal axes of rotation perpendicular to the longitudinal axis of the open-end spinning machine. The top of said cavity is covered by said first housing while the cavity forms said air collecting space, a central part of the bottom of said cavity being formed by said lid.

摘要： Open-end spinning unit with a spinning rotor having a lower side and an upper side. A lid is inserted into a front opening provided in said lower side, said lid being bored so as to form a fiber supply duct to convey separated fibers into the interior of said spinning rotor. A yarn take-off duct extends through said upper side of the spinning rotor and conveys the yarn via an outlet port out of the interior of the spinning rotor. A separator is secured to said lid and is designed to divide the rotor interior into a fiber supply zone and a yarn producing and take-off zone. The front surface of said separator which faces said yarn take-off duct constitutes a directing wall for directing the yarn end being returned to be spun-in, the circumferential edge of said directing wall being located in a space defined by a pair of planes perpendicular to the spinning rotor axis, one of said planes passing through the maximum yarn producing and take-off zone diameter and the other plane being spaced 6 mm therefrom in the direction toward the yarn take-off duct.

摘要： A method of separating fibers from a fibrous sliver and conveying them in this condition to a twist forming element of an open-end spinning unit. The fibers traverse a fiber separating zone which is formed by the annular space between a combing-out cylinder and the bore of a housing. Ambient air is sucked into this fiber separating zone as well as into a sliver feeding zone. The air being sucked in is the resultant of air flowing in planes perpendicular to the axis of the combing-out cylinder, in planes passing through said axis and in planes parallel to said axis.The apparatus for carrying out the aforedescribed method which includes a housing with a bore, a combing-out cylinder coaxially mounted in the bore, a sliver feeding device mounted in a cavity of the housing adjacent to the combing-out cylinder, and a lid covering the housing, but at least the region of the sliver feeding device being at least partially exposed to permit ambient air to be sucked into the sliver feeding and fiber separating zones.

摘要： A plurality of separate fiber slivers are introduced into spaced portions of a fiber-separating zone disposed in a combing cylinder-type fiber separating apparatus. The separated fibers are separately discharged into a common duct via a fiber-stripping zone associated with each combing cylinder. The regions of introduction of the separate slivers to the combing cylinder are suitably spaced so that the resulting separated fibers discharged into the duct form a common flow in the portion of the duct between the fiber-stripping zone and the downstream end of the duct. A yarn-spinning apparatus is disposed at the downstream end of the duct for receiving the common flow of the fibers, and such apparatus is mounted for rotation about an axis which is skewed with respect to the axis of the combing cylinder.

摘要： Apparatus for separating cotton type staple fibers from a fibrous sliver supplied to an open-end rotor spinning machine, said apparatus having a surface for supporting the so-called fiber beard of the sliver to be attacked by a card clothing of the combing cylinder. The dimensions and position of said support surface relative to the sliver feeding means and said card clothing are defined in dependence on the count of the sliver as well as on the gauge and staple length of the fibers to be processed. Such an optimization of the support surface dimensions and position makes it possible to attain an excellent evenness of fiber separation and consequently a good final yarn quality even with relatively low speeds of the combing cylinder, and also to reduce the risk of card clothing damage.
