 EMI2.1
 



   In order to be able to punch out porcelain crockery with a very small diameter, for which purpose the embodiments already described cannot be used well because the opposing knives leave only a small distance between them and also have to be set very obliquely to one another, another movement device is necessary to attach for the punching knife and bezw at the same time with the proven to be appropriate cover. Encapsulation of the guide pieces p to connect.



   This embodiment is shown in FIGS.



   The punch blades a are guided in the lower disk c1 as in the previously described embodiments. A cup-like part o1 is connected to the latter, the edge of which is provided with a corresponding number of guide slots into which the guide pieces p fit. As soon as all knives respectively. Guide pieces are used, a hood t is pushed over the guide pieces, which is mounted so as to be vertically displaceable and lockable on the central axis of the device. Each of the punching knives a, consisting for example of the four knife parts r (FIG. 8), is articulated to a pressure rail s, the upper free end of which can be pivoted up and down in an appropriate manner. In the case of very small devices, it is also possible to set two punching knives a lying next to one another in motion by a single rail s.
