  • Patent number: 11801649
    Abstract: 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.
    Type: Grant

  • Patent number: 10899390
    Abstract: A self-supporting underframe for a vehicle, the vehicle, and a production method thereof. The underframe has two elongate monocoques arranged parallel and spaced apart from each other and at least 50% closed on at least four sides, wherein the monocoques each have a single-part, trough-like element having at least one lower base and two side walls extending upwards from the base. At least one cover element closes the trough-like elements over at least 50% of the longitudinal extent of the particular trough-like element. The at least one cover element of each of the two monocoques in each case includes at least one cross-strut cover element, and the cross-strut cover elements of the two monocoques are designed as a common, single-part cross-strut cover element spanning an intermediate space located between the trough-like elements of the monocoques. The cover elements are fixedly connected to the side walls of the monocoques.
