  • Patent number: 8454876
    Abstract: Methods and apparatus for manufacturing an FC parison out of a laminate with at least two prepreg layers provide for: mounting at least a first edge section of the laminate in a first clamping device that can be moved relative to a fitting by means of a mechanical gearing, and a second edge section of the laminate lying opposite the first edge section in another clamping device, exerting a tensile stress via the first clamping device relative to the second clamping device over the area of the laminate lying between the clamping devices, while simultaneously moving the first clamping device in a direction directed away from the second clamping device up to a location where a rounded surface area of a fitting imparts to the laminate a curvature between the first clamping device and second clamping device as viewed in its longitudinal direction.
