und Ringzwirnmaschinen.and ring twisting machines.

Gegenstand der Erfindung ist ein Ring für Ringspinn- und Ringzwirnmaschinen, der seine Lauffläche entsprechend der verschiedenen Fadenspannung ändern kann. Ringe dieser Art sind zwar schon bekannt, indem ihre Wandungen infolge der eigenartigen Bauart der Ringe der Fadenspannung federnd nachgeben, doch kann diese Veränderung der Lauffläche naturgemäß nur innerhalb enger Grenzen sich bewegen.The invention relates to a ring for ring spinning and ring twisting machines, which is his Tread can change according to the different thread tension. Rings of this kind are already known because their walls are due to the peculiar design of the Rings of the thread tension give way, but this can change the running surface naturally only move within narrow limits.

Vorliegende Erfindung betrifft nun einen Ring, dessen Durchmesser und damit seine Lauffläche innerhalb weiter Grenzen veränderlich eingerichtet ist, indem der Ring nicht mehr geschlossen, sondern gespalten ist und bei Verengung des Durchmessers, die mittels einer eigenartigen Vorrichtung bewirkt wird, über sich selbst spiralförmig sich zusammenrollt.
■ Auf beiliegenden Zeichnungen stelltThe present invention now relates to a ring whose diameter and thus its running surface can be varied within wide limits, in that the ring is no longer closed, but split and, when the diameter is narrowed, which is effected by means of a peculiar device, spirals up on itself .

Wie die Fig. 1, 2 und 3 zeigen, besteht der Ring aus einer aus Flachmetall gebogenen Feder, die sich auseinanderziehen und verengern läßt. Der Ring kann auch gebohrt, gestanzt, gezogen oder gestoßen sein, je nach dem Grade der Biegsamkeit, die man ihm geben will. Er kann aus einem oder aus zwei übereinandergelegten Stücken bestehen, zwischen welchen der Läufer gleitet. Die Veränderung des Durchmessers des Ringes kann man mittels jeder Vorrichtung erzielen, die einen konzentrischen Druck erzeugt. Fig. 4, 5 und 6 zeigen beispielsweise eine solche Einrichtung, bei der der konzentrische Druck durch Rollen α bewirkt wird. Letztere sind lose auf den Zapfen b gelagert, die ihrerseits in radialen Ausschnitten c des Ringträgers d verschiebbar sind. Ein Deckel e, der gleichfalls mit Ausschnitten f für die Zapfen b versehen ist, ruft beim Drehen um die Achse g in der Pfeilrichtung (Fig. 4) ein Abrücken der Rollen α von der Achse g hervor, wodurch der Ring h sich infolge seiner Federkraft ausdehnt (Fig. 5). Die Drehung der Deckel e erfolgt durch Verschiebung der Zapfen i, die in einem Schlitz k seines Armes I geführt werden. Diese Zapfen i werden durch eine gemeinsame Welle verschoben, die durch nachstehende Anordnung in Bewegung gesetzt wird.As FIGS. 1, 2 and 3 show, the ring consists of a spring bent from flat metal which can be pulled apart and narrowed. The ring can also be drilled, punched, drawn or poked, depending on the degree of flexibility you want to give it. It can consist of one or two superimposed pieces, between which the runner slides. The change in the diameter of the ring can be achieved by means of any device which generates a concentric pressure. For example, FIGS. 4, 5 and 6 show such a device in which the concentric pressure is effected by rollers α . The latter are loosely mounted on the pin b , which in turn can be displaced in radial cutouts c of the ring carrier d . A cover e, which is also provided with cutouts f for the pin b , causes the rollers α to move away from the axis g when rotated about the axis g in the direction of the arrow (Fig. 4), causing the ring h to move as a result of its spring force expands (Fig. 5). The rotation of the cover e takes place by shifting the pins i, which are guided in a slot k of its arm I. These pins i are displaced by a common shaft which is set in motion by the following arrangement.

Auf der Exzenterwelle m (Fig. 9 und 10) ist ein Exzenter η befestigt, welches den Hebel 0 bewegt, der in p drehbar gelagert ist. Auf denOn the eccentric shaft m (Fig. 9 and 10) an eccentric η is attached, which moves the lever 0 , which is rotatably mounted in p. On the

Claims

1905 & 1 lever arm ο is supported by an angle lever q, which is pivoted in the upper part of the screw nut r. The nut is on the axially non-displaceable spindle s, which is guided in t and at the end of which is the gear u. The same is set in motion by the pawl ν, which in turn is moved by the levers w, χ and y. With each rise ίο of the lever w, the pawl ν rotates the teeth of the gear wheel u, which causes a rotation of the spindle s and thus an advance of the nut r and the lever q. Depending on how the bobbin (thread package) is formed, the Hebei q takes part in the alternating up and down movement of the lever 0, which is caused by the eccentric η. The vertical arm of the lever q ends in a roller z on which the curved stop 1 rests, which is wedged onto the shaft 2. This shaft 2 carries two levers 4 under the influence of the springs 3 and a lever 5 at each end, which are connected by hinges 6 to the pull rod 7, which extends through the length of the machine and the pins i and thus the cover e moves (Fig. 4 and 5). At the beginning of the stroke, since the pull rod 7 is under the influence of the spring 3 and the cover e is in the position shown in FIG. 4, all rings are closed to their smallest diameter; the runner can easily run over the ring "and the tension of the thread is low. Each time the lever w is lifted, the gear wheel u and the spindle s turn, the lever q moves forward over the lever 0, roller ζ lifts the lever / , Lever 4 rotates in the direction of the arrow drawn, with it the levers 5 sitting on the same shaft 2, which move the tie rods 7 by means of the hinges 6, which in turn moves the pins i and thus the cover e allows it to open and expand progressively as the spindle carriage descends so that, if the winding takes place at the lower end of the descending layer, the diameter of the ring will be greater than at the upper end of this layer Rotational movement continues, the lever 0 lowers and at the same time lever q and roller z with it. The spring 3 can contract again, the pull rod 7 is moved back by it, and the rings can move again progressively close so that when the winding takes place at the upper end of the ascending layer, the rings have their smallest diameter again. This alternating movement of the opening of the rings at the lower end of the yarn layer and their closure at the upper end (Fig. 7), which is caused by the non-circular disk η, takes place depending on the diameter at the base of the bobbin and when the base is done, the amount of movement of the lever q corresponds to the largest opening of the rings. At this moment a lever 8 throws back the pawl ν and prevents it from turning the gear further. The rings now open and close to the same extent at the top and bottom of each layer, and winding takes place just as easily at the top as at the bottom, since the tension of the thread has become the same in every position. 9 and 10 show the arrangement of the rings with variable diameter on a spinning machine in which the spindles perform an alternating ascending and descending movement with progressive ascending, the ring carriers being fixedly mounted. It can also be used in machines in which the spindles are mounted in a fixed spindle bank and the ring rail makes the ascending and descending movement. In the same way, the arrangement can take place in machines which form packages with conical ends (Fig. 8). In this case, the diameter of the ring remains the same during the formation of a layer, but gradually increases in proportion to the growing diameter of the coil. Pati: nt-Aν Proverbs:
