Definitions

  • the present invention relates to devices for forming the crowd of a weaving loom which comprises a plurality of systems for opening and closing the crowd.
  • Each system comprises movable plastic hooks which move vertically back and forth as well as two movable hook retaining hooks and an electromagnet, while each of these is provided with a tongue cooperating with the hook corresponding retainer in order to achieve what is called in the technique "leveling".
  • This operation consists in tilting the retaining hook by means of the tongue of the movable hook in order to press said retaining hook against the pole piece of an electromagnet.
  • a device of the kind in question is known from European patent 0219 437 of the present Applicant, the movable hooks of which are made of a suitable plastic material which gives the leveling tongue bending performance.
  • this tongue is subjected to very high friction and deformation stresses, even with the use of very high-performance materials, there is a risk of permanent deformation or creep of the tongue, the mechanical properties of which are thus altered.
  • a loss of elasticity of the tongue leads to leveling defects which lead to weaving defects.
  • the improvements which are the subject of the present invention aim to remedy these drawbacks and to allow the production of a tongue which does not lose its qualities of elasticity.
  • each tongue is in the free state pressing against a metal spring leaf provided with means for assembling the corresponding movable hook so that the reminder from each tab to its rest position is assisted by the reaction of the leaf spring.
  • Fig. 1 illustrates a crowd training device produced in accordance with European patent 0214075 which has been shown on an enlarged scale. Due to the cut, we see only a separating partition 1, the upper part of which supports an electromagnet 2, while two tilting retaining hooks 3 and 4 are mounted for free rotation around axes 5 and 6 integral of the partition 1. It is observed that these levers 3 and 4 are pushed back by springs 7, 8 so that their lower spout 3 a , 4 a is disposed in the rest state above the head 9 a , 10 has two movable hooks 9, 10 of the device, which are joined by a funicular element 11. We will not return to this structure which is well known by the aforementioned European patent.
  • each hook 9, 10 is provided with a tongue 9 b , 10 b of curved shape and which is roughly parallel to a face 9 c , 10 c of the body of each hook 9, 10.
  • each tongue 9b , 10b which is opposite the face 9c , 10c of the body of the hook.
  • This blade 12 has the general shape of a widely open V, the branches 12 a , 12 b of which terminate in curved ends in the direction of the apex 12 c of the blade. It is observed that the ends of the two branches, including their curved parts, are each provided with a blind slot 12 d , 12 e .
  • the spring leaf is of course made of spring steel or any other metallic material having the same elastic qualities.
  • a mobile hook has thus been produced, the tongue of which retains its elastic function thanks to the assistance of the spring leaf 12, the longevity is very important.

Claims (3)

  1. Fachbildungsvorrichtung eines Webstuhls, mit mehreren Systemen, welche zwei mobile Haken (9, 10) aus Kunststoff die jeweils mit einer biegsamen Zunge (9b, 10b) versehen und in vertikaler Richtung hin- und herschiebbar sind, einen Elektromagnet (2) sowie zwei schwenkbare Rückhaltehaken (3, 4) aufweisen, mit denen die Zungen (9b, 10b) der mobilen Haken zusammenwirken, um die Rückhaltehaken (3, 4) elastisch gegen den Elektromagnet (2) zu drücken, dadurch gekennzeichnet, daß jede Zunge (9b, 10b) im freien Zustand an einem metallischen Federblatt (12) anliegt, das mit einer Anschlußeinrichtung an den entsprechenden mobilen Haken versehen ist, damit die Rückwärtsbewegung jeder Zunge (9b, 10b) in Richtung ihrer Ruhestellung durch die Wirkung des Federblatts (12) unterstützt wird.
  2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß jedes Federblatt (12) eine weit geöffnete V-förmige Gestalt annimmt, deren geschlitzte Enden der Schenkel (12a, 12b) zum Scheitel (12c) hin umgebogen sind, auf dem die Innenfläche der entsprechenden Zunge (9b, 10) im freien Zustand aufliegt.
  3. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, daß die Vorderseite (9c, 10c) des Körpers der mobilen Haken zu jeder Zunge (9b, 10b) hin weist und mit zwei Rippen (9f, 9g - 10f, 10g) versehen ist, die mit den Schlitzen (12d, 12e) der Schenkel des Federblatts (12) zusammenwirken, wobei die von der Vorderseite vorspringenden Teile gegenüberliegend und in einem die Länge des Federblatts (12) übersteigenden Abstand angeordnet sind, wenn dieses in Folge der Verformung der Zunge (9b, 10b) flachgedrückt wird.
