After lifting the punch, the lower fora is moved to the side and the pia «" »« ϋϊϊΐΓνΓΰΐ DüWiö mlv gcvigaeben devices or stacked by hand. To increase the performance of such machines, one has sliding table press ^ which are fed alternately from both sides. Higher performing systems work with turntables. In all of these known machines and devices, completely identical plates must be used in each case be mowed, since the upper molding is only available once and on the press piston or a pressure piece is attached. So you have to move the same lower mold parts into the press again and again. For very large series is that also rational. The conversion of such machines to sin other format, however, requires one considerable effort, which can amount to a whole work platform. Frequent changes would therefore require considerable non-productive times. So must the manufacturer uses the machines for longer periods of time run with the same plate format. This will its delivery flexibility significantly affected. In many cases, however, different formats are constantly changing, for example a square plate and two different sized rectangular plates are required. For this the conventional machines would have to have two or be retooled three times. Especially in those

two oil fittings and additionally with different ones Form sets are worked in one work cycle, so that three different plate sizes can be produced in the same number of pieces. Small things are required for this Conversions. However, if the current requirement requires it, you can use the same device without retooling, just by changing the corresponding control, produce completely identical plates and then by switching switch to the other format.

The embodiment of FIGS. 5 and 6 is constructed in the same way in terms of the action and mode of operation of the molded parts and the upper molded part movement device. The press is also essentially the same, only here a turntable 80 is provided with a central column 81 on which the table 80 is rotatably guided with the aid of a long guide. It is also a three-column press with the two further outer columns 83a and 83b, which run on both sides of the upper molded part shifting carriage 50. The upper traverse 121 is correspondingly designed in a triangular shape. The lower cross member 122 is also triangular in shape. It only has one contact and support surface for the actual pressing process, because the jogging can take place elsewhere. The direction of rotation is indicated by 85. The turntable 80, as seen from the press 111, is followed by two depositing devices 91 for the various plate formats. This is followed by the first station, namely a paper insertion device 92 which, as the various rectangles show, is designed for inserting all the formats shown and with the help of a hydraulic cylinder and a corresponding carriage 94, which on guide

rails 95 is displaceable, the respective format 140 inserts into the mold. This is followed by the attachment filling device 113. The back-filling device 114 then follows. Furthermore, a pre-compression device 115 with a vibrator and a further pre-compression device 116 with a load are provided. All devices except for the press with the displaceable upper mold part carriage and the paper insertion device 92 are designed in the usual way. On the press and its associated elements, in particular the displacement device for the 6 upper wall sections, the same parts are provided with the same reference numerals as in the exemplary embodiment in FIGS. 1-4. The work cycle is accordingly and can be seen from the graphic representation, with the work being carried out in a rotating manner. A corresponding control ensures the flow and the movement of the individual members, the upper mold part carriage is shifted depending on the underneath reaching lower mold parts also here * This device allows an even more _, rational operation as the only "* embodiment according to FIGS. 1 to 4. However, it is structurally more complex.

Instead of to-and-fro upper-mold carriages running perpendicular to the feed direction of the lower mold parts these could also run in the same direction, provided there is space for it on the device. Of the vertical course ha «; However, the advantage that the next lying stations are not impaired. Should it be the space or the cycle as well make the machine structure appear sensible, the upper mold parts can also be moved in other ways. It is also possible to provide more than two different sets of molds on the sliding devices for the molded parts will. Then train the movement and control of Bind accordingly
