Die Erfindung 'bezweckt die Herstellung eines. Laufmantels, der auf einem Teil seiner Dicke durch· lose Fäden, insbesondere Baumwollfäden, die in der Masse eingebettet sind, verstärkt ist. Diese Baumwollfäden sind vollständig· unabhängig· voneinander und verlaufen in ebenen Schnitten, die senkrecht durch den den Mantel bildenden Ringwulst gelegt sind, wobei der Fußwulst aus einer Reihe von Fäden besteht, die ringförmig angeordnet und ebenfalls in eine Kautschukmasse eingebettet sind.The invention aims to produce a. Barrel jacket that is on part of his Thick through loose threads, especially cotton threads embedded in the mass, is reinforced. These cotton threads are completely independent of one another and run in flat cuts, which are placed vertically through the annular bead forming the jacket, the foot bead consisting of a It consists of a series of threads, which are arranged in a ring and also in a rubber mass are embedded.

Es ist bekannt, Laufmäntel aus segmentförmig gestalteten Gummistreifen herzu-It is known to produce barrel jackets from segment-shaped rubber strips.

'5 stellen. Nun werden gemäß; der Erfindung mit Gummi getränkte Fäden zu einem. Band zusammengesetzt, dessen Breite in an sich· bekannter Weise abwechselnd zunimmt und abnimmt, und zwar so1, daß1 die einzelnen Teile des Bandes Segmente des herzustellenden Reifens bilden. Die Teile werden darauf auseinandergeschnitten, in radialer Richtung über einen Kern gelegt und durch Pressen vereinigt.'5 places. Now, according to; of the invention with rubber soaked threads into one. Band composed alternately increases its width in per se known manner and · decreases, and in such a 1, that 1 the individual parts of the belt segments of the tire to form. The parts are then cut apart, placed over a core in the radial direction and united by pressing.

Eine geeignete Vorrichtung1 dient zur Ausübung dieses Verfahrens. Die getrennt voneinander durch ein Gummiband und dann durch einen Kamm, der in der Ebene des Fadenbündels hin und her geschwenkt wird, laufenden Fäden gehen dann zwischen Walzen hindurch, zwischen denen sie zu einem Band zusammengepreßt werden.A suitable device 1 is used to carry out this method. The threads running separately from one another by a rubber band and then by a comb which is pivoted back and forth in the plane of the thread bundle then pass between rollers, between which they are pressed together to form a band.

Die Zeichnungen veranschaulichen ein Ausführungsbeispiel des Erfindungsgegenstandes, sowie das Verfahren und eine Vorrichtung zur Herstellung des Mantels. Abb. r zeigt einen senkrechten Schnitt durch den Mantel in schematischer Darstellung, Abb. 2 eine Zusammenstellung· von Fäden, fertig für die Herstellung des Mantels. Abb. 3 ist eine Gesamtansicht einer Vorrichtung für die Herstellung des Mantels und Abb. 4 die Ansicht eines Teiles der in Abb. 3 veranschaulichten Vorrichtung. The drawings illustrate an embodiment of the subject matter of the invention, and the method and apparatus for manufacturing the jacket. Fig. R shows a vertical section through the Sheath in a schematic representation, Fig. 2 a compilation of threads, ready for the manufacture of the coat. Fig. 3 is an overall view of a device for the Manufacture of the jacket and FIG. 4 is a view of part of the device illustrated in FIG.

Der in Abb. 1 veranschaulichte Mantel besteht aus einer Masse von Kautschuk 1. In einem Teil der 'Kautschukmasse ist eine Reihe von Fäden· 2 angeordnet, welche in regelmäßigen, senkrecht durch Iden Mantel gelegten Sdhnittebenen verlaufen, die, erweitert, sämtlich' durch den Radmittelpunkt gehen würden. An den Fußenden des Mantels sind diese Fäden derart angeordnet, daß sie um den Fußwulstß geführt sind, welcher auf diese Weise mit der Masse des Mantels verbunden ist. Der Fußwulst 3 besteht seinerseits ebenfalls aus einer Kautschukmasse, in welcher Fäden 4 ringförmig, dem Umfang des Reifens folgend, in Ebenen angeordnet sind, welche demnach rechtwinklig zu derThe jacket illustrated in Fig. 1 consists from a mass of rubber 1. In part of the 'rubber mass is a number of threads x 2 arranged, which laid in regular, perpendicularly through the sheath Sdhnittplanes run which, extended, “all” go through the center of the wheel would. At the foot of the jacket, these threads are arranged in such a way that they are around the Fußwulstß are performed, which on in this way is connected to the earth of the jacket. The bead 3 in turn consists also made of a rubber compound in which threads 4 are arranged in a ring, following the circumference of the tire, in planes are, which are therefore at right angles to the

Ebene der Abb. i, parallel zur Radebene, verlaufen. Auf der Außenfläche des Mantels sind in an sich bekannter Weise Schutzschichten aus massivem Kautschuk 5 vorgesehen. The plane of Fig. I, parallel to the plane of the wheel. On the outer surface of the mantle protective layers made of solid rubber 5 are provided in a manner known per se.

Die Mantel nach der Erfindung können z.B. auf folgende Weise hergestellt werden: Man fertigt zunächst eine Anzahl von Streifen 6 an, in der Art, daß man eine gewisse Zahl von Baumwollfäden parallel durch ein Kautschukbad führt. Die Länge dieser Streifen 6 entspricht der Länge der Abwicklung des Mantelquerschnitts (Abb. 2). Man gibt den Streifen vorteilhaft die in der Zeichnung dargestellte Form, welche erhalten wird, indem man den Mantel in eine gewisse Anzahl gleicher Teile, z. B. 64, unterteilt. Ditrch Nebeneinanderlegen der 64 Teile mit dichter Berührung würde man also genau die Form des Mantels bekommen.The sheaths according to the invention can be manufactured, for example, in the following way: You first make a number of strips 6, in such a way that you have a certain Number of cotton threads running in parallel through a rubber bath. The length of these strips 6 corresponds to the length of the development of the jacket cross-section (Fig. 2). It is advantageous to give the strips the ones in the drawing The shape shown, which is obtained by dividing the jacket into a certain number of equal parts, e.g. B. 64, divided. Ditrch juxtaposing the 64 parts with close contact would be accurate get the shape of the coat.

Die Streifen werden nun bei geeigneter Temperatur und zweckmäßigem Druck behandelt, um ihre völlige Einbettung zu erreichen. Hierauf bringt man die so behandelten Streifen auf einen zweckmäßig gestalteten Kern, z. B. derart, daß man diese Streifen aneinanderlegt und eine gewisse | Zahl von Schichten aufeinanderlegt. Durch Druck werden diese verschiedenen Schichten und Streifen völlig unter inniger Verbindung der einzelnen Kautsrihukteile miteinander verschmolzen, so daß ein einheitliches Ganzes gebildet wird, und es völlig unmöglich ist, die ursprünglichen einzelnen Streifen noch voneinander zu. unterscheiden. Der Fußwulst wird derart hergestellt, daß man einen ringförmigen Kranz von Baumwollfäden durch ein Kautschukbad führt. Die Streifen, welche den Fußwulst des Mantels bilden sollen, werden an ihrem Ende derart getrennt, daß sie den Fußwulst vollständig umgeben (Abb. 1). Schließlich bringt man auf den in vorstehender Weise hergestellten Mantel noch die aus Kautschuk bestehende Schutzdecke 5 auf, worauf das Ganze, zwecks Verfestigung und Verschmelzung zu einem einzigen Block der Vulkanisation unterworfen wird. In Abb.3 und 4 ist eine.Vorrichtung zur Herstellung von Mänteln nach der Erfindung beispielsweise veranschaulicht. Ein Gestell 7 (Abb. 3) trägt eine Reihe von gleichlaufenden Rollen, über welche die Fäden 2 geführt werden. Nachdem diese Fäden über eine weitere Leitrolle 9 gelaufen sind, werden sie über eine Rolle 11, die in dem Kautschukbad 10 angeordnet ist, geführt. Beim Verlassen des Bades 10 werden die Fäden mit Hilfe eines Kammes 12 voneinander getrennt und hierauf einer Trocknung unterworfen, z. B. mit Hilfe eines Heißluftgebläses 13. Die Fälen gehen nun über eine Rolle 14 und von hieraus durch eine zweite Vorrichtung, deren Teile mit den Teilen 10, 11, 12, 13 und 14 ler beschriebenen Vorrichtung identisch sind. Von hieraus gelangen die Fäden auf eine Rolle 15, welche an Gestell 16 gelagert ist. Auf Gestell 16 sind ferner noch zwei weitere drehbare Rollen bzw. Walzen 17 und 18 vorgesehen, über welche die Fäden 2 geführt werden. Die Walze 17 ist mit einer Einbuchtung oder Rille versehen, welch der in Abb. 2 dargestellten Form des Streifens entspricht. Das Streichnetz der Fäden 2 erhält ■genau die Form dieser Einbuchtung mit Hilfe eines vor Walze 17 angeordneten Kammes 20, welcher von einem Arbeiter bedient wird, der dem Kamm die jeweils gewünschte Einstellung gibt. In Gestell 16 ist ferner noch: eine Walze 21 verstellbar angeordnet, deren Höhenlage vermittels eines Schraubengewindes 22 geregelt wird. Diese Walze ist mit Innenheizung ausgerüstet. Mit Hilfe der Walze 21 wird der Fadenstreifen, während er über Walze 17 läuft, unter Druck gesetzt. Auf Welle 18 erhält man schließlich ein verstärktes Kautschukband, welches in Stücke, deren Länge den auf Abb. 2 veranschaulichten Streifen entspricht, geschnitten wird. Die Herstellung des Mantels mit Hilfe der auf diese Weise erhaltenen verstärkten Kautschukstreifen erfolgt dann in der vorher beschriebenen Weise.The strips are now treated at a suitable temperature and pressure, to achieve their complete embedding. The strips treated in this way are then placed on a suitably designed one Core, e.g. B. in such a way that you put these strips together and a certain | Number of layers laid on top of one another. Pressure creates these different layers and strips completely with an intimate connection of the individual rubber parts with one another fused so that a unified whole is formed, and it is utterly impossible the original individual stripes still close to each other. differentiate. The bulge of the foot is made by passing an annular ring of cotton threads through a rubber bath. The Stripes, which are to form the base of the coat are separated at their end in such a way that that they completely surround the bulge of the foot (Fig. 1). After all, you bring up the Coat made in the above manner nor the protective cover made of rubber 5 on, whereupon the whole, for the purpose of consolidation and amalgamation into a single one Block is subjected to vulcanization. In Fig.3 and 4 is a device for Manufacture of jackets according to the invention exemplified. A rack 7 (Fig. 3) carries a number of co-rotating rollers over which the threads 2 are guided will. After these threads have run over another guide roller 9, they will guided over a roller 11 which is arranged in the rubber bath 10. When leaving of the bath 10, the threads are separated from one another with the aid of a comb 12 and then subjected to drying, e.g. B. with the help of a hot air blower 13. The traps now go over a roller 14 and from here through a second device whose Parts with parts 10, 11, 12, 13 and 14 ler described device are identical. From here the threads come to one Roller 15, which is mounted on frame 16. Two further rotatable rollers 17 and 18 are also provided on the frame 16, over which the threads 2 are guided. The roller 17 is indented or provided a groove, which corresponds to the shape of the strip shown in Fig. 2. The backing of the threads 2 is given exactly the shape of this indentation With the aid of a comb 20 arranged in front of roller 17, which is operated by a worker which gives the comb the desired setting. In frame 16 is also still: a roller 21 is arranged to be adjustable, its height position by means of a screw thread 22 is regulated. This roller is equipped with internal heating. With the help of the roller 21, the thread strip is while it runs over roller 17, pressurized. Finally, on wave 18, you get a reinforced Rubber tape, which in pieces, the length of which illustrated in Fig. 2 Strip corresponds to being cut. The manufacture of the jacket with the help of the reinforced rubber strips obtained in this way are then carried out in the manner previously described Way.
