摘要： A process and apparatus for piecing a yarn on spinning assemblies of an open end spinning machine is provided. A prepared yarn end is pieced to a sliver ring produced in a spinning rotor during running up of the spinning rotor from a predetermined slower speed toward its operational normal spinning speed. In order to accommodate application of the yarn end to the sliver ring, the formation of the sliver ring, and the drawing off of new yarn pieced together at the sliver ring, the invention provides for a control of the acceleration behavior of the spinning rotor so as to lengthen the time segment in which the piecing steps can be performed. In preferred embodiments, non-contact electromagnet or electrical eddy current braking means are provided for countering the driving torque of a common drive means for the rotors of several spinning assemblies, whereby the acceleration curve is flattened with a lengthening of the time period for existent desirable piecing speeds. In other preferred embodiments, inter-exchangeable spinning rotors of different diameters are provided with similar mass moments of inertia so as to exhibit similar flattened acceleration curves, even for very small diameter spinning rotors. In other preferred embodiments, driving mechanisms and/or braking mechanisms for the spinning rotor shafts are provided for controlling the running up or acceleration behavior.

摘要： Servicing apparatus is provided for servicing a multiplicity of spinning assemblies arranged side by side in open end spinning frame. The apparatus includes a plurality of part instruments for performing separate servicing operations at respective ones of the spinning assemblies, such as part instruments for cleaning, piecing up operations, and spindle bobbin exchanges. Since these part instruments are geometrically wider in the travel direction thereof than are the individual spinning assemblies, the invention involves a geometric arrangement of the various parts within the part instrument so as to accommodate simultaneous servicing of adjacent spinning assemblies by two different part instruments, without the part instruments blocking one another. In preferred embodiments of the invention the parts of the mobile instrument which must directly cooperate with the parts of the individual spinning assemblies are all arranged at one edge zone of the part instrument, with associated driving mechanisms and the like being located in another zone of the part instrument. In this manner, and by placing the respective edge zones of adjacent spinning machines as facing one another in the travel direction of the part instruments, it is possible to simultaneously serve immediately adjacent spinning assemblies without the part instruments blocking one another. In certain preferred embodiments, the height of the part instruments is so limited as to permit passage of the part instruments with respect to one another and also to permit simultaneous working at different parts of a spinning assembly by two different part instruments.
摘要翻译：提供维修设备，用于维护在开口纺纱机中并排设置的多个纺纱组件。该装置包括用于在各个纺纱组件中执行单独维修操作的多个部件工具，例如用于清洁，接头操作的部件工具和主轴筒管交换。由于这些零件工具在行进方向上比单独的纺纱组件在几何上更宽，所以本发明涉及零件工具中各种零件的几何布置，以便通过两个不同的零件工具同时维修相邻的纺纱组件，而不需要零件乐器相互阻隔。在本发明的优选实施例中，移动式仪器的必须与各个纺纱组件的部件直接协作的部件都被布置在零件工具的一个边缘区域处，相关联的驱动机构等位于零件仪器。以这种方式，通过将相邻的纺纱机的各个边缘区域沿着零件工具的行进方向彼此面对，可以同时服务于相邻的旋转组件，而不会使部件的装置彼此阻塞。在某些优选实施例中，零件工具的高度被限制为允许零件工具相对于彼此通过，并且还允许通过两个不同的零件工具在纺纱组件的不同部分同时工作。

摘要： A method and apparatus is provided for accommodating transfer of yarn supplied by an open-end spinning machine from a mobile piecing device to a spinning assembly. The yarn transfer apparatus includes a mechanism for automatically adjusting the speed of the yarn take-off during the transfer from the piecing device to the spinning assembly, for ensuring a continuous uniform denier of the yarn produced both before, during, and after the yarn transfer movement. Preferred embodiments include mechanisms for accommodating the shortening of the travel path between the spinning rotor and a winding spool at the spinning assembly resulting during this yarn transfer. Certain embodiments include direct control of the sliver feed to the spinning rotor so as to correspond to the change in speed of the yarn take-off during the transfer, while other embodiments leave the sliver feed unaffected while adjusting the yarn take-off mechanism to avoid changes in yarn take-off speed that would otherwise affect the quality of the yarn after the piecing operation.

摘要： A spinning machine arrangement is provided having fiber feeding and opening apparatus arranged upstream of the spinning turbine with respect to a supply of fibers to be spun. This apparatus includes a feeder roll and an opening roll arranged serially in the travel path of the fiber stream, said rolls being housed in a housing having one side formed by a flat baseplate. Individual separate guide parts are detachably attached to this baseplate for guiding the flow of fibers and air through the feeder roll and opening roll. These guide parts are constructed of different materials and machined to different tolerances in dependence upon the specific loads and requirements experienced in use due to the configuration and operation of the apparatus. A cover plate is disposed parallel to and in facing relationship to the baseplate, with the opening and feeder rolls, as well as at least a portion of the guide parts disposed therebetween. In preferred embodiments, the axle for the opening roll also operates as a pivot axis for the baseplate, with the opening roll being bearingly supported in the base plate. In this manner, pivotal movements of the baseplate effect engagement and disengagement of the opening roll with driving means thereof. At least some of the guide parts are attached to the baseplate to be adjustable in the radial direction with respect to the opening roll axis, so as to accommodate variable exact positioning thereof.

摘要： A servicing arrangement selectively displaceable along an open-end spinning machine which includes a number of individual spinning stations. At least one measuring head is arranged on the displaceable servicing means so as to selectively monitor the quality of the running thread or yarn at the individual spinning stations. A control apparatus is operatively associated with the measuring head and receives signals therefrom, whereby the control apparatus regulates elements for arresting a spinning operation at a spinning station and/or marks individual spinning stations and/or blocks a piecing operation at the spinning stations when the quality of the running thread or yarn at such stations is below a predetermined quality.

摘要： The fiber sliding surface and the fiber collecting groove of an open-end spinning rotor are provided with hard particles embedded therein. After a certain length of operation time of the spinning rotor, the particles in the fiber collecting groove have a larger particle size than the particles in the fiber sliding surface. Thus it is ensured that the fiber collecting groove has a better "grip effect" relative to the fibers to be spun than the smoother fiber sliding surface.

摘要： In the case of an open-end spinning machine, a suction roller is provided which serves to transport a fiber veil, expanding transversely to the circumferential direction of the suction roller, to a yarn formation line. The length of the transport path and the width of the fiber veil are determined by defining edges of a suction insert located inside the suction roller. At least one of the defining edges extends at least along a section of the transport path at an acute angle to the circumferential direction. Thus the fiber veil is widened in comparison to the sliver-shaped fed fiber material and/or the fiber tip at the beginning of the yarn formation line is shortened.
