DETAILED DESCRIPTION

[0025] In FIG. 1, a dough processing facility 1 is illustrated in a schematic side view. The dough processing facility 1 may comprise different working stations, which are disposed sequentially along a production direction R. The dough processing facility 1 may further comprise one or more supports 2. Dough may be depositable in different states onto a support 2. As illustrated in the present embodiment, the support 2 or supports 2, respectively, may be embodied as a conveyor band or conveyor bands, respectively. The dough processing facility 1 may comprise a dough stamping device 3. In the illustrated portion of the dough processing facility 1 the dough stamping device 3 may embody the first working station. A skilled person, however, will recognize that various working stations may precede the dough stamping device 3 in the dough processing facility 1, for example a dough sheeter (not shown). The dough processing facility 1 may further comprise a filling station 4. The filling station 4 may be disposed after the dough stamping device 3 in the production direction R. The dough processing facility 1 may further comprise a winding station 5. The winding station 5 may be disposed after the dough stamping device 3 and the filling station 4 in the production direction R.

[0026] The support 2 may be configured to convey a dough sheet 6. The dough sheet 6 may be depositable on the support 2. The dough sheet 6 may initially be delivered to the dough stamping device 3 by the support 2. The dough stamping device 3 may be configured to sever dough pieces 7. The severed dough pieces 7 may be transported from the dough stamping device 3 to the filling station 4 by the support 2. The filling station 4 may be configured to apply a filling 8 onto the dough pieces 7. This may in particular be a pasty filling 8, for example a fruit or nut paste. Subsequently, the dough pieces having the filling 8 applied thereon may be transported from the filling station 4 to the winding station 5. The winding station 5 may be configured to wind up the dough piece 7. In particular, the winding station 5 may be configured to wind up the dough piece 7 in such a way that the filling 8 is enclosed in the dough piece 7. After the winding, wound dough products 9 may be present.

[0027] In FIG. 2, the dough stamping device 3 is illustrated in a schematic frontal view, wherein the direction of view is indicated in FIG. 1 by the line II-II. Now it can be seen that the dough stamping device 3 may comprise a frame 10. The frame 10 may be built portal like. The support 2 may extend through the frame 10. The dough stamping device 3 may comprise a blade assembly 11. The blade assembly 11 may be disposed at a tool carrier 12. The tool carrier 12 may be movably connected to the frame 10. The blade assembly 11 may be movable with respect to the frame 10 and or with respect to the tool carrier 12. In particular, the blade assembly 11 may be configured to oscillate in a substantially vertical direction V. The blade assembly 11 may comprise a stripper 13. FIG. 2A shows the blade assembly 11 in a position disposed at an upper dead center, which in the following may be referred to as starting position A. In FIG. 2B, the same view is illustrated as in FIG. 2A. However, the blade assembly 11 is shown in a cutting position S. In the cutting position S the blade assembly may be lowered with respect to the starting position A towards the support 2.

[0028] In FIG. 3, a schematic view from below of the blade assembly 11 is illustrated. The direction of view is indicated in FIG. 2A by the line III-III. The stripper 13 can be seen. It can be further seen that the blade assembly 11 may comprise a first group 14 of blades 14a. The blade assembly 11 may further comprise a second group 15 of blades 15a.

[0029] In FIG. 4, schematic top views of the dough pieces 7 are illustrated, which may be severable from the dough sheet 6 by the blade assembly 11. The dough pieces 7 may each have an outer contour 16. Further, at least one slit 17, in the present embodiment three slits 17, may be provided in each of the dough pieces 7. The slits 17 may be disposed inside of the outer contour 16, particularly completely inside the outer contour 16. The blade assembly 11 may be configured to sever the dough pieces 7 from the dough sheet 6. The first group 14 of blades 14a may be configured to generate the outer contour 16. The second group 15 of blades 15a may be configured to generate the slits 17.

[0030] In FIG. 4, the dough pieces 7 are shown in different positionings with respect to the production direction R. Immediately after the severing by the blade assembly 11, the dough pieces 7 may initially be disposed in a severing position T. After that, they may be shifted into an aligned position P. In particular, the dough stamping device 3 may be configured to shift the dough pieces 7 from the severing position T into the aligned position P. For this purpose, the tool carrier 12 may be movably disposed at the frame 10. For example, the tool carrier 12 may be configured according to the disclosure of DE 197 20 689 A1 and related U.S. Pat. No. 6,158,315, the contents of which are incorporated by reference into the present disclosure.

[0031] The aligned position P may facilitate a winding up of the dough pieces 7. In particular, a winding edge 18 may be aligned in front with respect to the production direction R. The winding edge 18 may be the edge of the dough piece 7, at which the winding process is started. An imaginary winding axis 19 may extend along the winding edge 18. A winding up of the dough pieces 7 may occur around the winding axis 19. After shifting into the aligned position P, the dough pieces 7 may be transported to the filling station 4, in particular by the support 2, in the present embodiment the conveyor band. The filling station 4 may be configured to apply the filling 8 onto the dough pieces 7. For example, the filling station 4 may comprise a filling station conveyor (e.g., conveyor belt or band), which may be part of the support 2, for transporting the dough pieces 7 (e.g., in the production direction R) and/or one or more filling nozzles for applying a filling onto the dough pieces 7 disposed on the conveyor. After a further transport by the support 2, in the present embodiment the conveyor band, to the winding station 5, dough products 9 may be generated by the winding station 5 by winding the dough pieces 7 around the winding axis 19 starting at the winding edge 18. For example, the winding station 5 may comprise a winding station conveyor (e.g., conveyor belt or band), which may be part of the support 2, for transporting the dough pieces 7 (e.g., in the production direction R) and/or a winding mat and/or a winding board and/or a winding band and/or a winding belt and/or one or more hooks, wherein the winding mat and/or the winding board and/or the winding belt and/or the one or more hooks may each be engageable with the dough pieces 7 to facilitate winding of the dough pieces.

[0032] In FIG. 5, a wound up dough product 9 is shown in a schematic perspective view. FIG. 5 shows a wound up state Z of the dough piece 7. The dough product 9 is shown in a baked state. The baked state may be characterized in that the slits 17 have widened and exposed the filling 8.

[0033] In FIG. 6, a schematic sectional view of the dough product 9 is shown, wherein the cutting plane is indicated in FIG. 5 by the line VI-VI. The cutting plane extends through one of the slits 17. From FIG. 6 it can be seen, that the dough piece 7 may spirally extend around the winding axis 19 in the wound state. It can also be seen that the slit 17 may spirally extend around the winding axis 19.
