Shaping device for continuous shaping

A forming device, system, and method for continuous forming of a semi-finished fiber product. The semi-finished fiber product is supported flatly from a first side and is at least locally restricted in its freedom of movement, for example pressed on and/or guided, on another side opposite the first side. The further restriction occurs in relation to a guiding area at at least one constant location or region past which the semi-finished fiber product is guided. Shaping tools and guiding areas defined thereby are used for support, and hold-down devices and their contact surfaces are used for further restriction. The further restriction is carried out transversely to a feed motion direction of the semi-finished fiber product through the forming device. The further restriction and the flat guidance serve to reduce formation of undulations and folds.
