    In Fig. 1 is a perspective view of the plunger 1 with a view on the underside or on the press rings 11 a, 11 b, 11 c, ... shown. The inventive device 10 for processing dough comprises at least one pressure stamp 1. An embodiment of the pressure stamp is shown in FIG. The plunger 1 comprises seven pressing rings 11a-11g, the first pressing ring 11a being arranged in the center of the pressing rings 11a-11g. The first press ring 11a is formed fully cylindrical. Around the first press ring 11a, the second press ring 11b is arranged. The pressing ring 11b is arranged concentrically in a plane with the pressing ring 11a and lies with its inside against the first pressing ring 11a. The third press ring 11c, the fourth press ring 11d, the fifth press ring 11e, the sixth press ring 11f, and the seventh press ring 11g are each concentric with the first press ring 11a and are arranged side by side in a staggered manner. In this case, the first press ring 11a has a slightly smaller outer diameter than the inner diameter of the second press ring 11b. Analogously to the outer diameter of the first press ring 11a and the inner diameter of the second press ring 11b, the further press rings 11c-11g are telescopically arranged one inside the other, wherein in each case adjacent pressing rings, such as the press ring 11b with the press ring 11c or the press ring 11c with the press ring 11d, arranged displaceably relative to one another with respect to their ring axis 14. The pressing rings 11a-11g are respectively supported and guided on the inner periphery and the outer periphery on the adjacent pressing rings 11b-11g. The guidance of the pressing rings 11a-11g allows a displacement of the pressing rings 11a-11g to each other and thus allows a staggered displacement of the individual pressing rings 11a-11g. The plunger 1 has on one of its side surface arranged on the plunger 1
    Drive device 20 on. The drive device 20 comprises a camshaft 21 (FIGS. 2 to 4) and an electric motor 22, which can rotate the camshaft 21 in its axis 27. Around the largest or outermost press ring 11g around an edge ring 12 is arranged on the plunger 1. The pressing rings 11a-11g have a flat end faces and are arranged coplanar in a plane in a first position (FIG. 2) and in the first position form a flat end face 13 of the pressure ram 11.
    In Fig. 2 is a sectional view of the plunger 1 is shown in a first position. The pressing rings 11 a - 11 g are arranged coplanar in the first position, so that their end faces form a flat end face 13 of the plunger 1. The pressing rings 11a, 11g are arranged so as to be telescopically displaceable relative to one another in the ring axis 14. The plunger 1 has a radially extending to the ring axis 14 of the pressing rings 11a - 11g recess 15 which completely passes through the pressing rings 11a - 11g and the plunger 1. The drive device 20 has a motor 22 and a camshaft 21 in this embodiment. The camshaft 21 is completely inserted into the recess 15 and extends coaxially to the circular or cylindrical recess 15. The camshaft 21 has fourteen cams 23b to 23g and 24a to 24g. The camshaft 21 is thereby introduced into the recess 15 such that seven of the cams 23b to 23g come to lie on one side with respect to the ring axis 14 and the other seven cams 24a to 24g lie on the diametrically opposite side of the ring axis 14. The cams 23b to 23g and 24a to 24g respectively act on or contact a pressing ring 11a to 11g. The cams 23b to 23g and 24a to 24g are arranged in pairs, wherein the respective cam pairs 23a and 24a act on the same pressing ring 11a and are arranged diametrically opposite the ring axis 14 along the camshaft 21. The cams 23a to 23g and 24a to 24g of the camshaft 21 are further in each case at two diametrically opposite points of the wall of the recess 15 and the axis 27 of the camshaft 21 at. Upon rotation of the camshaft 21 in the axis 27 is about the cam 23a to 23g or 24a to 24g of each of the cams 23a to 23g or 24a to 24g hinged press ring 11a to 11g adjusted in the direction of the ring axis 14 and slides and slides each at the adjacent press ring 11a - 11g, for example, the third press ring 11c on the two press rings 11b and 11d, along and is guided by this. The plunger 1 further has an edge ring 12, whose inner diameter is made larger than the outer diameter of the largest press ring 11g. The edge ring 12 has a
    Negative shape of the edge of the dough piece to be pressed and has in this embodiment, a semi-circular mold.
    Fig. 3 shows the plunger 1 of the device 10 according to the invention in a second position according to the sectional view shown in Fig. 2. The second position of the press rings 11a-11g is present, for example, after the pressing operation of a dough piece, wherein in this second position the press rings 11a-11g are staggered and the outermost press ring 11g is extended furthest. The shape of the cams 23a to 24g determines in each case the position of the pressing rings 11a to 11g to one another or the course of the position of the pressing rings 11a to 11g to each other and their distance from the support 13 and the dough.
    The device 10 further comprises a limiting device which sets and specifies the minimum and maximum spacing of the pressing rings 11a to 11g from the support 3 and the abutment, respectively. A detailed view of the limiting device is shown in FIG. 4. The limiting device consists in this embodiment of a wedge system. Between each cam 23a to 24g and the respective pressing ring 11a to 11g, a wedge pair 81 to 87 and 91 to 97 are arranged (Fig. 2, Fig. 3). The wedge pairs 81 to 87 and 91 to 97, are in each case diametrically opposite each other with respect to the ring axis 14 between the respective press ring 11a to 11g and the corresponding cam 23a to 23g and 24a to 24g. The wedge pair 81 connects the cam 23a with the pressing ring 11a, diametrically with respect to the ring axis 14, the wedge pair 91 is arranged analogously between the cam 24a and the pressing ring 11a. The further wedge pairs 82 to 87 and 92 to 97 are likewise arranged in pairs with respect to the ring axis 14 at respectively between two cams, for example the cams 23b and 24b, and the second press ring 11b. Depending on the thickness of the wedge pair 81 (FIGS. 2, 3), the maximum or minimum distance between the respective press ring 11a to 11g and the support 3 is changed and adjusted. The wedge pair 81 consists, as well as the other wedge pairs 82 to 97, of a first wedge 81a and a second wedge 81b, each diametrically opposite between the respective cam 23a to 24g and the wall of the recess 15 and the respective press ring 11a to 11g are arranged.
    6 shows a detailed view of a wedge, here the second wedge 82b, which has the same curvature as the press ring 11b with the cam 23b and is arranged congruently with the press ring 11b (FIGS. 2, 3, 4). The first wedges 81a to 87a and the second wedges 81b to 87b are each formed as a wedge ring segment and each have the same average diameter as the pressing rings 11a, 11b to 11g, on which the respective wedge 81a to 87b is arranged. The wedges 81a to 87b have a varying thickness along their circumference, with the thickness increasing uniformly over the circumference or uniformly increasing or decreasing from one end of the wedge 81a to 87b (FIG. 6) to the other end thereof. The increase or decrease in thickness of the keels 81a to 87b forms an inclined plane inclined to the base of the respective wedge 81a to 87b as shown in Fig. 6 for the keel 82b. The respective wedge pair 81 to 87 thus forms with the respective cam 23a to 24g of the camshaft 21 in each case two touch levels lying parallel to one another. The thickness of the first wedge 81a and second wedge 81b, respectively, lying between the camshaft 21 and the pressing ring 11a determines the position of the pressing ring 11a with respect to the camshaft 21 via the thickness of the wedges 81a and / or 81b (FIG. 4). , By twisting one of the wedges 81a, 81b or the wedge pair 81 or the pairs of wedges 82 to 87 and 91 to 97 about the ring axis 14 and thus the change in the voltage applied to the cam 11a thickness of the wedge pair 81 is the depth of descent or the distance between the respective press ring 11a to 11g and the support 13 and the abutment adjusted. The rotation of the remaining wedge pairs 82 to 87 or 91 to 97 analogous to the wedge pair 81 also causes an adjustment of the distance to the support 3 of each of the wedge pair 82 to 87 arranged press ring 11 b to 11 g.
    To adjust the wedge pairs 81 to 87 and 91 to 97, the first wedges 81a to 87a and 91a to 97a are each arranged on an adjusting ring 90a to 90g, wherein in each case the adjusting rings 90a to 90g have the same inner diameter and outer diameter as the respectively arranged underneath press rings 11a to 11g (Fig. 4) and are arranged on this on the support 13 remote end face of the pressing rings 11a to 11g. For the suspension of the adjusting rings 90a to 90g and the pressing rings 11a to 11g, four guide pins 89a to 89g are respectively provided, which hang or support the adjusting rings 90a to 90g or the pressing rings 11a to 11g on a retaining disk 88. The retaining disk 88 has in each case in the region of the guide pins 89a to 89g a slot-like recess extending over a peripheral region, whereby the guide pins 89a to 89g in these recesses and thus the pressing rings 11a to 11g or the adjusting rings 90a to 90g are rotatable in an angular range. By rotation of the pressing rings 11a to 11g or the adjusting rings 90a to 90g, the thickness of the wedges or wedge pairs 81 to 97 arranged thereon is changed in each case and thus the exit depth of the pressing rings 11a to 11g or the distance between the pressing rings 11a to 11g and changed the edition 13.
    For the production or processing of dough, in particular the production of pizza bases, the process according to the invention will be described below by way of example with reference to FIGS. 6a and 6b:
    For the production of pizza bases or other pieces of dough, a dough piece 6, shown in Fig. 6a, placed on the support 3 of the device 10 (Fig. 2, Fig. 3). The plunger 1 is positioned in height above the support 3, so that the innermost pressing ring 11a comes to rest over the dough piece 6. The pressing rings 11a to 11g are now brought onto the dough piece 6 in a sequence, so that the dough of the dough piece 6 begins to flow. For this purpose, the pressing rings 11a to 11g are lowered successively, staggered from the innermost pressing ring 11a to the outermost pressing ring 11g, from the first position (FIG. 2), in which the pressing rings 11a to 11g are arranged coplanar and form a flat end face 13 of the pressure ram 1, wherein the pressing rings 11 a to 11 g act on the dough piece 6 and the dough piece 6 increases its area under the pressure of the pressing rings 11 a to 11 g. The pressing ring 11a is the first from the first position down in the direction of the support 3 and acts on the dough piece 6, so that it increases its area. By rotation of the camshaft 21, the pressing rings 11b, 11c to 11g are now successively lowered and act successively on the dough piece 6. The cams 23a to 24g or the camshaft 21 are designed such that a sequence of lowering of the pressing rings 11a to 11g takes place and after a predetermined pressing time the respective pressing ring 11a to 11g is lifted off the deformed dough piece 6 again. It is always only a part of the pressing rings 11a to 11g with the dough piece 6 in contact, wherein the contacting pressing rings are each adjacent pressing rings. The lowering movement of the pressing rings, which is caused by the camshaft 21, resembles a waveform that is carried out from the center of the plunger 1, so the ring axis 14 of the compression rings 11a to 11g outwardly to the outermost press ring 11g. The resulting wave-like propagation of the dough piece 6 causes an enlargement of the surface of the dough piece 6 in the radial direction and causes the production of the knitted dough piece or a pizza base. After lowering the last press ring 11g and the largest press ring 11g this is held in position, so that the dough flows into the optionally present edge ring 12 and forms the edge of the dough piece. The wave-shaped lowering and re-raising of the pressing rings 11a to 11g thereby causes an advantageous flow movement of the dough of the dough piece 6 without this tearing or unfavorable stresses on the dough.
    In Fig. 7, a further embodiment of the device 10 is shown in a perspective view. The device 10 has two pressure pistons 100, 200, which are arranged on a mobile frame, in this embodiment a trolley 300. The first plunger 100 is arranged opposite to the second plunger 200, wherein the ring axes of the compression rings 111a to 111g of the first plunger 100 and the pressing rings 211a to 211g of the second plunger 200 are arranged concentrically with each other. The pressing rings 111a to 111g of the first pressure ram 100 and the end face 113 of the first pressure ram 100 face the end face 213 of the second pressure ram 200 and the end face of the pressing rings 211a to 211g of the second pressure ram. The pressing rings 111a to 111g of the first pressure ram 100 and the pressing rings 211a to 211g of the second pressure ram 200 are in each case adjustable towards the opposite pressure ring of the opposing pressure ram 100, 200. In this embodiment of the device 10 according to the invention, the first pressure ram 100 is the support or the abutment of the second pressure ram 200 and the second pressure ram 200 is the support or the abutment of the first pressure ram 100. A dough piece 6 in this embodiment of the device according to the invention 10 placed on the second plunger 200 and the described pressing process by both plunger 100, 200, either delayed or synchronized, executed simultaneously. The arrangement of the two pressure pistons 100, 200 allows a variable shape of the dough piece or a different thickness profile of the pizza base or the dough piece over the diameter. The pressure plungers 100, 200 are each fastened to an adjusting device 4a or 4b, the adjusting devices 4a and 4b being formed by a hydraulic cylinder. The adjusting 4a and 4b allow the adjustment of the plunger 100, 200 to each other. Fig. 8 shows a sectional view of the device 10 described in Fig. 7, wherein the adjusting means 4a, 4b and the trolley 300 or the frame are not shown. The second plunger 200 is the same design as the first plunger 100, wherein the second plunger 200 has no edge ring 12. The arrangement of the two pressure pistons 100, 200 enables an improved wave-shaped kneading device, wherein both pressure pistons 100, 200 synchronized from the center to outwardly perform a wave-like kneading movement and deform a dough piece 6, optionally arranged between them, uniformly to a pizza base or another dough piece.
    As an alternative to the above-described press rings 11a to 11g, a different number of press rings can also be present, it also being possible for the thickness of the press rings or the shape, in particular the end face, to be profiled.
