FIG. 9 shows a cross section of a preferred embodiment of the first or second press station 601 or 602 with a flat lower mold and a corresponding upper mold in the compressed state.

The upper mold 760 is attached to a plate 701 which is height-adjustable on slide rods 715 , 716 . This plate 701 is located thereabove further connected via a hydraulically controlled toggle mechanism 705 having an on the slide bars 715, 716 disposed plate 702, wherein the toggle mechanism 705 achieved the actual pressing operation.

A hydraulic mechanism 710 is provided above both plates 701 , 702 , which presets the lifting position of the toggle mechanism 705 . The hydraulic mechanism 710 is attached to a frame 720 for holding the slide rods 715 , 716 .

As shown in FIG. 9, the lower mold and the upper mold have a flat shape when compressed, so that the hydraulic mechanism 710 is extended far.

A case analogous to FIG. 9 with a deep shape corresponding to a deep shape of the part to be pressed is shown in FIG. 10.

Therein, the same reference numerals designate the same parts as in FIG. 9, and the explanation thereof will be omitted below.

In particular, according to the arrangement shown in FIG. 10, the hydraulic mechanism 710 is hardly extended due to the deep shape.

As shown in FIG. 9 and 10, the hydraulic mechanism 710 must accommodate the pressure of the hydraulically controlled toggle mechanism 705 during pressing. Therefore, in the embodiments shown in Figs. 9 and 10, there is a disadvantage that the hydraulic mechanism must be large and requires a large amount of oil to be adjusted.

This problem can be avoided by a further preferred embodiment of the first and second pressing stations 601 , 602 , which is shown in FIG. 11.

Fig. 11 shows a cross-section of this further preferred embodiment, the pressing station having a flat shape and corresponding counter-shape in the relaxed (uncompressed) state.

In FIG. 11, the same reference numerals in FIGS. 9 and 10 show the same parts and will therefore not be explained again.

As can be seen from FIG. 11, the hydraulic mechanism in this embodiment has a substantially smaller shape, because it is only used to adjust the lifting height of the two plates 701 and 702 . In contrast to the examples shown in FIGS. 9 and 10, the hydraulic mechanism no longer has to absorb the pressure of the toggle mechanism 705 .

For this purpose, ie to take up the pressure of the toggle mechanism 705 , in the embodiment shown in FIG. 11, notches 780 and corresponding raster devices 790 are attached to the upper plate 702 on the slide rods 715 , 716 . This pressure is thus advantageously diverted via the frame of the slide rods 715 , 716 , and therefore the hydraulic mechanism 710 can be dimensioned correspondingly small.

Although according to the above-described embodiments Press device according to the present invention on the Pressing roofing tiles made of ceramic mass was, however, is the pressing device according to the present Invention in principle on the pressing of any parts interpretable.

Although according to the above-described embodiments of the left and right pressing station at most two to be pressed Parts have been fed is an extension to more than two parts to be pressed easily possible.
