      Fadenbremsapparat    für     Textilmaschinen.       Bei den bisher bekannten     Fadenbremsap-          paraten,    bestehend aus zwei, gegeneinander  drückenden Bremsplatten,     bestand    der grosse       Nachteil,    dass, die     gewöhnlich        aus    gehärte  tem Stahl hergestellten     Platten    sich durch  den Faden rasch     einschneiden    liessen, da vor  und nach des     Fadenbremsapparates.        feste          Fadenleitorgane    vorgesehen werden mussten,

    welche den Faden     während,des        Durchlaufens     durch die Bremsplatten an eine     bestimmte     Stelle     fixierten.    Zweck !der Erfindung ist  nun, diesem Übelstand abzuhelfen, indem  mindestens einem der dem Bremsapparat     vor-          geschalteten        Fa,denleitorgane    eine Bewegung  erteilt wird, durch die der Faden stets seine       Durchlaufstellung    zwischen den Bremsplat  ten     ändert.     



  Zur Erläuterung diene nachfolgendes       Ausführungsbeispiel          Fig.    1 zeigt eine Seitenansicht,       Fig.    2 Draufsicht eines     Fadenbremsappa-          rates,          Fig.    3 Schnitt     A-B    durch die geschlos  senen Bremsplatten,         Fig.    4 Schnitt     A-B    durch die offenen       Bremsplatten.     



  Auf     einer        Tragstange    1     ist    ein Support  2 befestigt, in welchem .die beiden Brems  platten 3 und 4 angeordnet sind.     Platte    3 ist  beweglich um den     Scharnierstift    5,     während-          ,dem    Platte 4     mittelst        Schraube    6 auf dem       Support    2     befestigt    ist.

   Das. an einem Bind  faden 7 und     in,der    Rolle 8     hängende        Gewicht     9 zieht je nach Grösse des     Gewichtes    9 die       Platte    4 mehr oder weniger     fest    gegen die       Platte    3, wodurch die dem durchlaufenden  Faden 10     erteilte    Spannung geregelt     wird.     Auf einer weiteren     Tragstange    11 ist der  Hebel 14 mit Rolle 15 befestigt, die in ent  sprechender Weise     :gegen:

          eine    sieh drehende  Hubscheibe 16 gespiesst wird.     Fadenleitor-          gan    17 dient zur     leichten        Einführung    des  Fadens;

       zwischen    die     Bremsplatten,    während  das     Fadenleitorgan    18 den Faden, nach dem  Durchlauf en, durch die     Bremsplatten,        in        ge-          wo@llter        Richtung    weiter     leitet.    Durch die  Drehbewegung der     Hubseheibe    1-6, bewegt  sich nun der     Fadenführer    13 beständig zwi-      scheu :

  der in     Fig.    1 fest     eingezeichneten        und     der     punktierten    Stellung, somit     wandert        auch.     der Faden in der     Berührungsebene    der beiden       Bremsplatten    3     und    4     andauernd    zwischen  .den beiden eingezeichneten Stellungen, wo  durch ein Einschneiden :des     Fadens    in die       Bremsplatten    '3,     resp.    4     ausgesohlossen        ist.  



      Yarn braking device for textile machines. In the previously known thread brake devices, consisting of two brake plates pressing against one another, there was the great disadvantage that the plates usually made of hardened steel could quickly be cut by the thread, as before and after the thread brake device. fixed thread guides had to be provided,

    which fixed the thread in a certain position while passing through the brake plates. The purpose of the invention is to remedy this inconvenience by giving at least one of the guiding elements connected upstream of the braking apparatus a movement by means of which the thread always changes its passage position between the braking plates.



  The following exemplary embodiment serves as an explanation: FIG. 1 shows a side view, FIG. 2 shows a plan view of a thread brake apparatus, FIG. 3 section A-B through the closed brake plates, FIG. 4 section A-B through the open brake plates.



  On a support rod 1, a support 2 is attached, in which .die two brake plates 3 and 4 are arranged. Plate 3 is movable around the hinge pin 5, while the plate 4 is fastened to the support 2 by means of a screw 6.

   The. on a binding thread 7 and in, the roll 8 hanging weight 9 pulls the plate 4 more or less firmly against the plate 3, depending on the size of the weight 9, whereby the tension given to the thread 10 passing through is regulated. On another support rod 11, the lever 14 is attached with a roller 15, which in a corresponding manner: against:

          a rotating lifting disk 16 is speared. Thread guide 17 is used for easy introduction of the thread;

       between the brake plates, while the thread guide 18 forwards the thread, after it has passed through the brake plates, in the desired direction. As a result of the rotary movement of the lifting disc 1-6, the thread guide 13 now moves constantly between:

  the firmly drawn in Fig. 1 and the dotted position, thus also migrates. the thread in the contact plane of the two brake plates 3 and 4 constantly between .den two positions shown, where by cutting: the thread in the brake plates' 3, respectively. 4 is excluded.
