摘要： The invention relates to a method of and a system for controlling the operation of open-end spinning machines comprising a plurality of spinning units, which method is based upon a permanent cyclic communication of a central unit of the system with the individual spinning units. According to the invention, at a given instant, a single spinning unit only is connected to the central unit of the control system, said central unit being supplied with information data about the condition of the spinning unit connected thereto while said central unit simultaneously transmits instructions for said spinning unit, the other spinning units operating automatically on the basis of the stored instruction the validity of which lasts for the time of one control cycle.

摘要： Improved yarn spinning-in process and apparatus in open-end rotor spinning units which raises the quality of the spun-in point in the yarn to a level comparable with the quality of the entire yarn length. The yarn open end is pieced on to high-quality fibers while low-grade fibers are separated from the high-quality fibers and do not participate in the spinning-in process.

摘要： An arrangement for tensioning the end of an inserted weft for beat-up of the weft into a fell by a rotary reed is described. An elongated weft-gripping mechanism is movable forwardly opposite the direction of movement of the portion of the reed which engages the weft being inserted along an axis oblique to the rotary reed into a frontmost position where it engages a weft carried by each of a succession of weft inserters as soon as the inserter has moved past the end of the reed into which the weft has just been inserted. A pair of jaws on the outer end of the gripping mechanism then close to grip the engaged weft and to move it rearwardly into a securing position between a thrust plate and a toothed, weft-guiding disc coaxial with the rotary reed. After the weft is secured, the jaws of the gripping means open and the gripping mechanism is moved forwardly again to grip the next weft.

摘要： An improved technique for presetting the adjustment cams that move the heddles of a travelling wave loom between their upper and lower shed-forming positions as described. The succession of control cams or guiding members, which engage actuating butts on the lower ends of the successive heddle members in the weaving region of the loom, are carried by a first endless conveyor; the succession of guiding members includes spaced adjustment portions including a slider element having three superposed cam track junction portions. A control section in the form of a travelling endless program member resembling a second endless conveyor upstream of the weaving region is selectively coupled to a link which engages a roller supported on the slider of each adjustment portion of the succession of guiding members. The link is movable into three positions corresponding to the three positions of adjustment of each slider. Facilities are described for securing each slider in its adjusted position, and for indicating an alarm and/or a loom stopping mechanism if the slider inadvertently moves out of its adjusted position prior to reaching the weaving region.

摘要： A travelling-wave loom is provided with a pair of endless chains which respectively carry a plurality of weft inserters and a plurality of winding units for feeding weft threads from associated bobbins to the weft inserters. The chain carrying the winding unit is formed from a plurality of spaced rigid carrier members interconnected by standard links. Each carrier member has a groove for removably receiving the winding head, and when in position a spring-loaded pawl affixed to the carrier member releasably secures the winding head in the groove of such carrier member. Such chain also carries transversely spaced sets of rollers which are individually supported on opposite sides of an oval guide rail. One of the roller sets is spring-loaded to maintain the carrier member in firm contact with the guide surfaces.

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： 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.
