Definitions

  • a method and apparatus for electrically operating elements, such as yarn brakes, yarn cutting devices, windolf accessories and feed mechanisms, mounted within or on a yarn package carrier comprises inductively transmitting the necessary AC electrical voltage across an air gap needed for ballooning yarn thereby permitting the external control of the above-mentioned elements.
  • the primary of a transformer is mounted on a balloon limiter or on a separator and opposite this primary, in the yarn package carrier, a corresponding secondary of the transformer is installed with the primary and secondary components of the transformer being in reciprocal relation with one another across the air gap for the ballooning yarn.
  • the present invention relates to a method of and apparatus for the operation of a multiple twist, spinning, slubbing or like machine.
  • This problem is solved according to the invention by means of a method which comprises influencing the controllable functional elements electrically and transmitting inductively across an air gap for the ballooning yarn. This is done by means of an AC voltage and preferably with more than 50 c./s., even though frequencies up to or above 20 kc./s. can be used.
  • the alternating current may have a sinusoidal curve or consist of individual pulses which can have for example sawtoothor square form.
  • the method according to the invention provides on the one hand a central setting of the controllable functional elements from one place and on the other hand it is possible to act on the particular control elements individually.
  • brakes for example must be set laboriously at each spindle e.g. brakes for the twist-flyer and for the yarn, it is now possible to bring this about in a simple way by varying the voltage centrally and it is also possible, in certain cases, to act individually on each spindle. Obviously group actuations are also possible.

  • Opposite to this primary there is provided in the yarn package carrier the correspondingly installed secondary of the transformer.
  • the two parts are in respective relation over the air gap necessary for the transit of the yarn.
  • one such transformer is provided; in certain circumstances it is also possible to arrange several such transformers on the periphery which are then connected in each case to a controllable functional element. It may be expedient to connect a rectifier between the functional elements and the secondary of the transformer, in order that DC motors or even DC-supplied magnets can be attached.
  • the terminals of the secondary of the transformer can be applied to an electromagnetically excited yarn brake; they can also be applied to an electromagnetic brake for a rotating draw-off accessory, for example a twist-flyer, and in these instances it is also possible to work with a rectified voltage.
  • a yarn cut-ofl device can also be operated.
  • Such a severing arrangement can advantageously be put under the influence of a yarn controller or of a bobbin thickness measurer. Moreover operation from a central point or by hand at each spindle is possible.
  • the invention also makes it possible to provide, inside the yarn supply package carrier, a yarn feed or drawing mechanism.
  • a yarn feed or drawing mechanism By means of the feed mechanism it is possible to apply positive traction to the yarn in the input tube and thus to exclude variations in tension of the yarn, which result from withdrawal from the supply package and effect a rotation stop.
