Device for automatically replacing thread bobbins and spooling device

A process for producing different types of windings, especially a flyer winding or a composite winding, in the formation of a spool on a core sleeve of a spindle in a draft-twisting machine or frame in which, instead of displacing the ring rail over the full height of the spool to be formed, the full height is subdivided into zones and the ring rail is reciprocated in each of these zones only through a fraction of the total structure of the ring rail. During the winding in each zone, the spindle speed is held approximately constant and the spindle speed is changed only upon a transition from one zone to another.

Method of producing different types of spool windings, especially flyer

A high speed yarn winding device performing a parallel winding, with the winding having yarn windings which intersect within each winding layer. The parallel winding is formed on a sleeve rotatably and interchangeably mounted on a carrying device through a driven friction roller. The friction roller is partially looped by the yarn to be wound on and a yarn winding body involved in a winding of the yarn abuts at its outer circumference with the friction roller. A guide bar is adapted to execute lifting movements parallel to an axis of rotation of the friction roller, with the bar carrying a rotatably mounted wheel driven by the yarn fed to it and coming in contact with it and superimposing much more rapid and shorter modulating strokes on the relatively slow lifting movements of the guide bar. To improve the winding conditions of the yarn and the composition of the parallel winding, the wheel has at least one round drive surface concentric to the axis of rotation. The yarn cooperates with the drive surface so as to drive the wheel. A yarn transport device is connected in series with the wheel and delivers the yarn to at least one yarn deflecting element disposed concentrically on the wheel. At least one yarn deflecting element deflects the yarn to the friction roller.
