Abstract
A device for shaping a semi-finished fiber product for manufacturing a C-shaped or I-shaped former, and including clamping mechanisms and a forming tool. Each clamping mechanism has a first and a second clamping element and together they hold a semi-finished fiber product along two longitudinal and opposite edges. The clamping elements and forming tool move in a coupled manner between starting and end positions. During this movement, the longitudinal edges of the semi-finished fiber product are transformed into a curved shape, wherein a length of one of the longitudinal edges of the semi-finished fiber product does not change and a length of the other longitudinal edge becomes greater. During the movement, the forming tool is transformed into a curved shape and guided relative to the clamping elements against the semi-finished fiber product such that the semi-finished fiber product is deep drawn over the forming tool.
