A shaping shoulder has a shoulder part and a prism part, joined at a shaping edge, for producing a web, shaped longitudinally in the web transport direction and having an open or closed cross-section and at least one area inside the web in which the cross-section is curved outwardly. The shoulder part has a web inlet and extends from the web inlet to the shaping edge. The prism part has an exit for the shaped web and extends from the shaping edge to the exit. The shaping edge is slanted relative to a cross-sectional prism plane. The prism cross-section is curved partially inwardly and outwardly not only in the vicinity of a web edge. The curvature of areas of the shaping edge belonging to outwardly curved areas of the prism part extend counter to the exit and the corresponding shoulder part areas are curved away from the exit.

1. A shaping shoulder for producing a web shaped longitudinally relative to a transport direction of the web and having an open or closed cross-section and at least one area inside the web in which the cross-section is curved outwardly, the shaping shoulder comprising:a shoulder part and a prism part joined to one another at a shaping edge; wherein the shoulder part has a web inlet and extends from the web inlet to the shaping edge and wherein the prism part has an exit, where the web exits after shaping as a shaped web, and extends from the shaping edge to the exit; wherein the prism part has a longitudinal extension in the transport direction of the web along the prism part toward the exit and has a cross-section perpendicular to the longitudinal extension; wherein the shaping edge is slanted in a direction toward the exit relative to a plane of the cross-section of the prism part; wherein the cross-section of the prism part has inwardly curved areas and outwardly curved areas located at least in the vicinity of a web edge, wherein the shaping edge is slanted less relative to the plane of the cross-section of the prism part at the outwardly curved areas of the prism part than at the inwardly curved areas of the prism part. 2. The shaping shoulder according to claim 1, wherein the shoulder part is comprised of several shoulder components arranged on both sides of the web.3. The shaping shoulder according to claim 2, wherein some of the shoulder components are formed as a roller.4. The shaping shoulder according to claim 1, wherein, for shaping a double tube from a single film web, in an area of the prism part (3) correlated with a web center of the web, the cross-section of the prism part (3) has a straight area (20) adjoining on both sides of the web center, wherein the outwardly curved areas are connected to the straight area.5. The shaping shoulder according to claim 1, wherein, for shaping a parallel tube chain, the prism part (3) beginning at a web center of the web is partially inwardly curved and, after closing a cross-section of the web and forming a seam on the web, again curves outwardly.6. A device for producing longitudinally shaped webs with a closed cross-section, the device comprising:a shaping shoulder according to claim 1, removal members arranged underneath the shaping shoulder and configured to grip the shaped web in the form of a tube formed by the prism part at overlapping areas. 7. The device according to claim 6, wherein the removal members comprise one or several roller pairs or grippers.8. The device according to claim 7, wherein, when several of the roller pairs are provided, the roller pairs can be operated with different speed.9. The device according to claim 7, wherein, when several of the grippers are provided, the grippers are operated with different removal stroke.10. The device according to claim 6, wherein the removal members are configured as welding members.11. A shaping shoulder for producing a web shaped longitudinally relative to a transport direction of the web and having an open or closed cross-section and at least one area inside the web in which the cross-section is curved outwardly, the shaping shoulder comprising:a shoulder part and a prism part joined to one another at a shaping edge; wherein the shoulder part has a web inlet and extends from the web inlet to the shaping edge and wherein the prism part has an exit, where the web exits after shaping as a shaped web, arid extends from the shaping edge to the exit; wherein the prism part has a longitudinal extension in the transport direction of the web along the prism part toward the exit and has a cross-section perpendicular to the longitudinal extension; wherein the shaping edge is slanted in a direction toward the exit relative to a plane of the cross-section of the prism part; wherein the cross-section of the prism part has inwardly curved areas and outwardly curved areas, wherein the outwardly curved areas are defined by an inner angle of the prism part that is greater than 180 degrees, located at least in the vicinity of a web edge, wherein the shaping edge is slanted less relative to the plane of the cross-section of the prism part at the outwardly curved areas of the prism part than at the inwardly curved areas of the prism part.
