  • the clamping rail 21a likewise has an abutment or reference edge 23 for forming a flange region 24, on which the corresponding side of the semifinished product 10, preferably its longitudinal side 12, is brought into abutment.
  • the clamping rail 21a as a component of the clamping module 21 can have a plurality of holding devices 25 arranged along the longitudinal direction 22, which are preferably designed as clamping devices or clamping jaws 25, which are preferably arranged at a uniform distance from one another on a preferably flexible clamping rail or a spring steel band 26.
  • the Clamping devices attached by means of connecting elements or by adhesive connections from the spring steel strip 26.
  • These clamping devices 25 can have a front surface 27, which faces the web area 2, and a rear surface 28.
  • Both the sewing frame 52 and the sewing frame 82 can alternatively also be designed in such a way that no holding device 54 for forming a foot is arranged or can be used at the edge region 1b.
  • a clamping module 21, a fixing device 16 or another type of clamping device can be provided on the sewing frame 52 or the sewing frame 87 for holding or clamping the edge region 1b.
  • a spacer or cavity filler or, preferably, a gusset 65 can be inserted between corresponding layers 63a, 63b of the (sub-) preform 20 in step 50 to form a foot 5 at the edge region 1b Longitudinal direction of the foot, or runs according to the course of the kink. This is preferably done when the Preform 20 is located in the workpiece holder 52 or 82.
  • a preferably provided gusset 65 is shown in Figure 8b.
  • the spacer can also be designed differently, in particular with regard to its cross-sectional shape, depending on the application. It is essential that it can be inserted between layers of the preform 20 and keeps the respective layers apart.
