Steam locks for feeding and discharging a web of material preferably for high pressure.

The invention relates to a steam lock for the inlet and Removal of a web, preferably for a high pressure container.

The main problem with high-pressure containers is that the material web without pressure and steam loss, both in the Container lead in and out of it. There is nor the requirement that the material web at these locks may not be subject to mechanical stress in any way.

The invention is based on the object of a steam lock to create, on the one hand, relatively cheap to manufacture > is, works flawlessly and does not require any maintenance.

S. The invention is that two pairs of rollers each of K> ribbons enclosed in the running direction of the web such reasonable ^~: riind arranges that the co-rotating average $ ruma dense itself "

Rolling a wall connected to the container housing ' and at the implementation points, the strand is elastic Seals are provided for the passage of the same "

With that the problem of entry and exit is in a very simple way The material web is discharged into a high-pressure container, whereby the seal does not only take place in one line, which is particularly important when the associated sealing rollers are bent there is a risk of leakage, but there are practically sealing surfaces, since the parallel to each other Trums of the belts the - "web of goods over a longer distance relax between you and take it with you.

In the drawing are exemplary embodiments of the invention shown »It show:

1 shows a lock in a schematic cross section, FIG. 2 shows a lock in section near the line AB in FIG. 1 _; Figure 3 shows another embodiment.

In the exemplary embodiment in FIG. 1, the steam lock 1 consists of a box 3 which can be placed on the high-pressure container and is provided with reinforcing ribs 2. The box 3 is provided in the lower part with a passage slot 4 for the web 5 to pass through. §0 9811/0683

To pass through the web 5, two pairs of rollers 6, 6 'and 7 * 7 * are arranged, each surrounded by strips 8 and 9, which are arranged in the running direction of the web in such a way that the concurrent central strands 8 ¹ , 9 ¹ form a seal place them next to each other and enclose the web of goods to be taken between them. Of the roller pairs 6 and 7, one roller is arranged in the interior of the box 3 and one roller, namely rollers 6 'and 7', outside the box, with a wall 10 being arranged in the space between the belts, which are located on the guides of the strands of the bands δ and 10 elastic ₄ seals extending over the entire width of the bands>

11 wears * Di * seals 11 lie lip-like from both of them Pages on the straps 8 and 9 passed through and enclose them between them so that no steam escapes is possible.

The bands 8 and 9 are preferably made of steel, since steel can have a very smooth surface, so that the seal is guaranteed. Of course you can too Plastic tapes or plastic coated tapes use find, it is essential and decisive that the strips 8 and 9 have an absolutely smooth surface so that there is no drive at the sealing points and, above all, the sealing is guaranteed.
