Machine à filer à anneaux avec, pour chaque poste de filage, un détecteur particulier (302; 346) qui émet un signal, lequel peut être évalué aussi bien pour indiquer une casse de fil que pour indiquer un "état d'avance lente" de la broche (116, fig. 1) attribuée au détecteur, et une analyse de performance (PCB; SL) qui évalue le signal aussi bien après la présence d'une casse de fil qu'également après un état d'avance lente de la broche (116), et où l'analyse de performance (PCB; SL) travaille en coopération avec un moyen d'indication, lequel indique la présence d'un état d'avance lente,
    caractérisée par le fait que
    le moyen d'indication comprend des indications (306; 316,318; 348) qui sont prévues chacune près d'une broche (116) attribuée à l'indication en question.
  2. Machine à filer à anneaux selon revendication 1,
    caractérisée par le fait que
    l'analyse de performance (PCB; SL) peut provoquer l'illumination de l'indication (306; 316,318; 348) d'un poste de filage concerné par un état d'avance lente.
  3. Machine à filer à anneaux selon revendication 2,
    caractérisée par le fait que

  5. Machine à filer à anneaux selon l'une des revendications précédentes,
    caractérisée par le fait que
    le détecteur (302; 346) produit un champ magnétique.
  6. Machine à filer à anneaux selon l'une des revendications précédentes,
    caractérisée par le fait que

  7. Machine à filer à anneaux,
    caractérisée par le fait qu'une indication particulière (306; 316,318; 348) est attribuée à chaque poste de filage pour indiquer l'état "d'avance lente de la broche".
  8. Machine selon revendication 7,
    caractérisée par le fait que
    l'attribution est choisie de telle manière qu'une personne de service, qui se trouve près de cette indication (306 ; 316,318 ; 348), doit se tenir également près du poste de filage concerné par l'état d'avance lente.
  9. Machine selon revendication 7 ou 8,
    caractérisée par le fait que
    l'indication (306; 316,318; 348) montre d'une manière non équivoque quel poste de filage est concerné par un état d'avance lente, et où l'indication (306; 316,318; 348) est, de préférence, perceptible visuellement, par exemple, sous forme d'une lampe de signalisation.
  10. Machine selon revendication 9,

    caractérisée par le fait que
    les indications individuelles (306; 316,318; 348) des postes de filage sont complétées par des indications de grands espaces (LLA, LLB), lesquelles peuvent effectuer le service, depuis relativement loin, dans un lieu qui est approprié comme point de départ pour la mise en marche de l'indication (306; 316,318; 348) d'un poste de filage concerné.
  13. Machine selon revendication 12,
    caractérisée par le fait qu'une indication de grands espaces (LLA, LLB) est prévue par face de machine, à au moins une extrémité de machine, de préférence à chaque extrémité de machine.
