The invention relates to a continuously operating machine for producing one of two outer ones Top layers and a middle filling layer of existing dough sheet. They are machines for this purpose known, the two groups of dough rollers (primary rollers) together with feeding devices for the separate shaping of the Dough existing top layers, an insertion device for inserting the filling layer between the dough layers brought together with the help of conveyors, a further group of rollers (secondary rollers) for rolling out the three-layer dough sheet produced and a device for depositing the Have dough band on a steady means of transport. In the known machines, the one Primary roller group formed dough layer with a filler, such as fat, sugar, Cream, etc., and then the top layer formed in the other primary roller group on the Filler layer applied. This mode of operation requires a horizontal design of the machine correspondingly high space requirements, with lengths of up to 12 m and more. Such large machines can no longer be supervised by a single person, so that because of the need for a second operator result in increased operating costs. Besides, it's because of the horizontal design of the machine, the introduction of a new one and, in particular, the re-threading a torn strip of dough is very difficult and can only be done by particularly skilled operators. One must take into account that the re-threading of the torn dough sheet normally has to be done with the machine running.

There are also standing machines with primary roller groups for separate molding of one each Dough sheet together with feeding devices and with an insertion device for inserting the filling layer known between the layers of dough brought together with the help of conveyors, but the do not work steadily and do not deliver dough strips. Rather, the stationary machines are used for Step-by-step production of filled shaped dough pieces, each of which has a single piece at the end one work cycle is discharged from the machine. Since the production of these fittings is cyclical, So if it takes place discontinuously, strains and upsets of the dough layers are unavoidable, those of the filling point running steadily from the primary rollers. This plays a role in the production of filled dough pieces, the machine that is no longer rolled out after filling

practically no role. But if you wanted to convert the well-known stationary machines - or. add that the resulting three-layer dough structure is then rolled out and made a steady one Means of transport would be abandoned, because of the aforementioned strains and compressions never a three-layer sheet of dough with a uniform and consistently small thickness of the dough layers produce.

The task is therefore to create a dough forming and layering machine that is able to three-layer dough strips of even and consistently small thickness, the two outer layers of dough and contain a middle filler layer, to be produced without distortion, and the lowest possible Has space requirements. The inventive solution to this problem is the combination of a plurality some of the characteristics known per se. The machine according to the invention is designed upright, the primary rollers and their feeders on either side of the feeder for the filling compound are located. The conveyor to bring the two together in the primary rollers separately formed dough layers are arranged below these rollers that the dough layers After the merging, leave a vertical gap between you, in the with the help of the insertion device filling compound is continuously entered from above. From the place of creation of such resulting three-layer dough band by the one used to roll out this band Secondary rollers up to the inlet of the depositing device mentioned at the beginning is essentially one vertical guide provided for the three-layer tape. The depositing device has a per se known Way, two endlessly revolving conveyor

In the machine according to the invention, both of the doughs produced in these groups of rollers are In contrast to the known version, the 5 layers 19 and 20. To bring the two endlessly revolving conveyor elements such two dough layers 19 and 20 serve two such designed and supported buckle, that the passage below the primary roller groups 2, 3 and 4, S and passage slot in each position of the conveyor elements one of the insertion device 6 arranged constant rollers Has length and its lower discharge tracks 7 and 8 that the dough layers 19 and 20 end in a constant small distance from io after merging a vertical one after the means of transport in a horizontal plane leave open gap between you. In these and moved. Gap can with the help of the device 6 steadily a

The machine according to the invention enables the suitable filling compound to be entered from above.
