Abstract: The device for cutting and separating dough from continuously/cyclically guided strips of dough, has conveyor (4) and cutting unit with tool bar (6) with knife-like cutting tools, which are supplyable by lifting drive for carrying out cutting movements on the dough strip present on the conveyor and are removable from this. A longitudinal guidance of the tool bar provided with a linear drive, oriented on transportation- and dough strip-movement direction in order to cause a separation of the cut passing vertically to this movement direction, from the dough strips. The device for cutting and separating dough from continuously/cyclically guided strips of dough, has conveyor (4) and cutting unit with tool bar (6) with knife-like cutting tools, which are supplyable by lifting drive for carrying out cutting movements on the dough strip present on the conveyor and are removable from this. A longitudinal guidance of the tool bar provided with a linear drive, oriented on transportation- and dough strip-movement direction in order to cause a separation of the cut passing vertically to this movement direction, from the dough strips. The cutting unit with the tool bar proceeds in the movement direction around a given amount under taking the cut of the dough sequence. The tool bar is provided with a rotary drive for revolving of the tool bar and exhibits polygonal cross sections and several knife plates, on which in each case different cutting tools or cutting tool combinations are fastenable. On each of the side surfaces, a knife plate is arranged exchangeably. The rotary drive with a rotation axis passing in longitudinal direction of the tool bar stands in effective connection in its internal running axis of rotation of the tool bar. In the movement direction of the cutting unit, a relocatable rotation-spreading mechanism (17) transverse to the movement direction, is intended. The rotation-spreading mechanism comprises a working head, which receives a rotary drive (7) and which is displaceable from a linear drive in transverse direction oriented on the movement direction. The rotary drive has hollow-cylindrical axle, which stands in connection with a receiving plate, on which bolts are arranged in order to lead a needle plate movable perpendicular to the movement direction for fixing the dough. On the ends of the bolts, a stripper plate is fastened, which exhibits passage openings. In the hollow-cylindrical rotary drive axle, a lifting cylinder is arranged, whose cylinder bar stands in connection with the needle plate. The rotation-spreading mechanism is arranged on an additional linear guidance (20) passing in the movement direction in order to move this mechanism out of a working position near the tool beam into a bar distance-maintenance position. The structural units from the receiving plate, the needle plate and the stripper plate are easily solvable from the rotary drive and lifting cylinder. Both the working head and the linear drive are enclosed in transverse direction in dust proof manner. For the enclosure of the transverse direction-linear drive, brush strips partly overlapping the rotation-spreading mechanism are intended, which lock a passage gap. Within the area of the passage gap, a coupling flange is present, which carries the respective working head and which stands in connection with the transverse direction-linear drive. In the section of the cutting movement carried out below the conveyor by means of the tool bar with one of the knife plate, a rotary endless belt as cutting base is arranged, which stands partially in contact with the lower surface of the conveyor (4) and which is dragged along with this during the movement of the conveyor.
