Description

  

      Fadenabschneidvorrichtung    an     Webstühlen    mit     Schusswechselapparat.       Den Gegenstand der vorliegenden Erfin  dung bildet eine     Fadenabschneidvorrichtung     an Webstühlen mit     Schusswechselapparat.     



  Auf der beiliegenden     Zeichnung    ist eine  beispielsweise Ausführungsform des Erfin  dungsgegenstandes dargestellt, und zwar zeigt:       Fig.    1 eine Seitenansicht der Vorrichtung,       Fig.    2 eine Ansicht von links in     Fig.    1  unter Weglassung und Schnitt einiger Teile,       Fig.    3 einen Vertikalschnitt nach der  Linie     A-A    der     Fig.    2.  



  Ein Aufnahmestück 1 weist eine Bohrung 2  auf, mit welcher es an eine Stange 3 gesteckt  und an derselben mittelst einer Schraube 4  festgehalten ist. Die Stange 3 ist in einen  mit     Schusswechselapparat    ausgestatteten Web  stuhl eingebaut. Das Aufnahmestück 1 besitzt  zwei seitliche Platten 5, in denen eine Achse 6  drehbar gelagert ist. Auf dieser sitzt eine am  Umfang mit Schmirgelbelag 7 verkleidete  Walze 8 fest. An den über die Platten 5  vorstehenden     Endteilen    der Achse 6 sitzt  einerseits     ein-    Stellring 9 und anderseits eine  am Umfang mit spitzen Zähnen versehene  Antriebsscheibe 10 fest. An einem am Auf  nahmestück 1 festsitzenden Träger 11 sind    mittelst zweier Bolzen 12 zwei aneinander  liegende Flachfedern 13 befestigt.

   Zwischen den  selben ist ein um die Walze 8 gelegtes endloses  Band- 14 hindurchgeführt, welches von der  Walze 8 in umlaufende Bewegung versetzt  wird. Des fernem ist am Aufnahmestück 1  ein Scherenhebelarm 15 festgeschraubt, wel  cher     angelenkt,    einen zweiten Scherenhebel  arm 16 trägt. Dieser steht unter Wirkung  einer Schraubenfeder 17.  



  Die Wirkungsweise des beschriebenen       Fadenabschneiders    ist folgende  Der seitliche Rand des vom Webstuhl  hergestellten     Stoffes    wird, in     Fig.    2 betrachtet,  rechts vom Aufnahmestück 1 und damit an  den beiden Flachfedern 13     vorbeibewegt,     wobei das Antriebsrad 10 in den sich über  dasselbe hinwegbewegenden     Stoff    eingreift,  von diesem gedreht- und mit dem Band 14  in Umlauf versetzt wird. Hierbei kommen  die seitlich am Stoffrand vorstehenden Faden  enden auf das Band 14 aufzuliegen, mit  welchem sie zwischen den Flachfedern 13       hindurchbewegt    werden, bis dieselben von  der Schere 15, 16 abgeschnitten werden.

    Die Schere wird     zweckmässigerweise    durch      die     Ratiere    des     Webstuhles    betätigt, mit  welcher sie durch ein am Scherenhebel 16  angreifendes, über eine Leitrolle 18 geführtes  Zugorgan 19 verbunden ist.



      Thread cutting device on looms with gunshot apparatus. The subject of the present invention is a thread cutting device on looms with a gun gun.



  In the accompanying drawing, an exemplary embodiment of the subject of the invention is shown, namely: Fig. 1 is a side view of the device, Fig. 2 is a view from the left in Fig. 1 with the omission and section of some parts, Fig. 3 is a vertical section according to the Line AA of FIG. 2.



  A receiving piece 1 has a bore 2 with which it is plugged onto a rod 3 and held on the same by means of a screw 4. The rod 3 is installed in a chair equipped with a gunshot web. The receiving piece 1 has two lateral plates 5 in which an axis 6 is rotatably mounted. A roller 8 covered on the circumference with an emery coating 7 sits firmly on this. On the end parts of the axle 6 protruding beyond the plates 5, an adjusting ring 9 on the one hand and a drive pulley 10 provided on the circumference with pointed teeth on the other hand are firmly seated. On a fixed on the take-up piece 1 carrier 11 two adjacent flat springs 13 are fastened by means of two bolts 12.

   Between the same, an endless belt 14 placed around the roller 8 is passed, which is set in rotating motion by the roller 8. Furthermore, a scissors lever arm 15 is screwed to the receiving piece 1, wel cher hinged, a second scissors lever arm 16 carries. This is under the action of a helical spring 17.



  The mode of operation of the thread cutter described is as follows: The lateral edge of the fabric produced by the loom, viewed in FIG. 2, is moved to the right of the receiving piece 1 and thus past the two flat springs 13, with the drive wheel 10 engaging the fabric moving over the same this is rotated and set with the belt 14 in circulation. The threads protruding laterally on the edge of the fabric come to rest on the band 14 with which they are moved between the flat springs 13 until they are cut off by the scissors 15, 16.

    The scissors are expediently actuated by the ratchet of the loom, with which they are connected by a pulling element 19 which engages on the scissor lever 16 and is guided via a guide roller 18.
