Device for vulcanizing tires in the mold under pressure.

The vulcanization of soaps, in particular the vulcanization of Jüiederhermistellenden Heifenmäiiteln, usually takes place, after appropriate preparation and accommodation in a mold, by inserting a rubber chamber into the interior of the Ilantel. ^; then compressed air with the required pressure is introduced so that the jacket being processed can adapt itself completely to the walls of the shape. In this way, the coat to be treated hot is completely restored .. .- "..

However, the use of the air chambers introduced into the annular interior space of the jacket involves difficulties. So "" / versehleißtidie made of / rubber. Luftkamme.r _s exposed to high temperatures, very quickly and must be renewed frequently,

2 -

This increases the cost of repair ... strong, the repair can also located "jacket" can be damaged if the · air chamber is loaded beyond the permissible limits and about bursts ..

In addition, in modern high-performance repair machines, the Use of compressed air chambers of the known type is problematic, and the need for a new system has already been repeatedly pointed out by interested industry been.

The increase in price fulfills the requirements for a simple and quick restoration of the tire oil while avoiding all of the disadvantages mentioned, in that the pressure chamber to be introduced into the jacket is completely eliminated. Rather, the inside of the soap jacket itself is used to form a completely annular pressure chamber into which compressed air is then introduced to generate the pressure to apply the jacket against the walls of the mold.

Various devices are shown in the drawings;

1 and 2 show the overall arrangement in cross-section with the annular devices consisting of one or more pieces _? which are inserted into a shell in the mold,

Fig. 5 shows an annular elastic device, which is changeable in shape under the action of the compressed air, in

Figures 4 and 5 are annular devices with an air pressure seal shown,

Fig. 6 is an annular device with a double air pressure seal acting externally on the jacket, and

FIG. 7 shows a detail from FIG. 6.

According to Figure 1 of the drawings, the device consists of a Sing 1 with end faces 2, which, made in one piece, preferably made of solid rubber: - or consists of an elastic material and must be variable in shape at the same time. A tube 3 with a valve through which the compressed air is fed leads through the ring. "~ -"

The ring-shaped device 1 is inserted into the jacket 4 to be repaired mounted, which is in a form of known type. The introduction takes place so that the surfaces 2 against the inner surfaces 6 of the corresponding opposite sections 7? about, the bulges pressure-exerting a pressure on the jacket. When the Tulkanisierforin- over the luantel 4 is closed, creates its chamber 8 in this way, the atLS the coat itself and the ring 1 is formed. This chamber is completely tight. -

By de, s valve 3 the compressed air is now admitted into "the Ksjiimer 8, which takes on the function of a pressure chamber d. H. Yrerden does not use any special aids such as the well-known aerial chambers. This can therefore be saved. The width of the hanging must be a little bigger than the sf / ischen. the sections 7 of the jacket existing distance so that a pressure-tight seal is achieved,

In another embodiment, the annular device. As FIG. 2 shows, consist of a ring 9, which has special sealing pieces 10 and .11 on the end faces. These sealing pieces act on the face 6 of the sections 7s giving the same result is achieved, as in the embodiment according to FIG. 1..

In. Fig. 3, the ring-shaped device consists of a spring ring 12 ,. which is provided with elastic sanders 13 and 14. These edges iVben a "constant pressure on the outer surface and ensure the perfect tightness of the resultingan chamber.8.

In Fig. 4, a metal ring 15 is provided through which a valve tube 3 was passed through and one on each of its faces The hat is cut out for the seat of two hollow diagonal strings 17 and 18. These are by means of pressure of the corresponding pipe 19 supplied compressed air inflatable.

Fig. 5 shows a Vo.rrichtttng with a hollow, two Eingplatten 22 ύοϊι Hing The plates have beads 24 and 25 help NIIT the mentioned seal ring held us 2-3 'of upper and lower, carried Dichtung.gring 21, is . Sr can thereby inflate the pressure of the compressed air guided through a corresponding drilling line 26 and thus seals off the Iriiienraum 8.

Be another ax form, according to fig. 6 and 7 ordered the device, which in this case is particularly suitable for soaps with large dimensions, from a hanging 27 _{5 of} the two annular beads 28 in which grooves 29 for the attachment of. Seals are provided .. Each hollow sealing ring 30? äer exerts pressure on the surface 35 of the jacket section is connected to an ear 3Ί, which in turn represents the upper section of another tube 32. This is in connection with the drill 33s which is passed through the inlet 27. The ear 33 is at the bottom, on which the tube, with valve. 34 is attached., Closed / Through the ".! Tube the compressed air is simultaneously led into the chamber 8 of the jacket and the hollow sealing rings 30. ·.

In this case, too, the Alipressung of the ".Tire is guaranteed to the surfaces of the vulcanizing mold by the air pressure acting directly on the inner surface of the chamber 8 of the casing 4, the pressure-tight seal being achieved via the hollow sealing rings 30, which as already mentioned, act on the inner surface 35 α.βτ shell sections . "-. . -. .

The devices do not require any special "maintenance" as they are robust and are easy. A possible escape of air, this can only gradually going forward, there is a rapid and total loss of pressure impossible, can be done by sealing with conventional aids be prevented. A rupture of the devices "is" as long as the vulcanization machine is closed can not. An advantage of great importance .is that the devices for the most diverse Soaps are to be used, provided only the inside diameter and widths are the same.
