ABSTRACT:
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.
