Patent ID: 7856895

Claim:
A device for acquiring and correcting deviations between a desired contour and an actual contour of a large area flexible component, taking into account the component's own weight, comprising: a plurality of stamps arranged on a base area to form a stamp field for accommodating the large-area flexible component at points of support, wherein each stamp comprises at least one force measuring sensor for measuring a weight force F m that acts at the point of support, and at least one distance measuring sensor for measuring a travel path S m travelled by the stamp, and a computing unit for each point of support for determining a theoretical weight force F g and/or a theoretical travel path S g from component data, wherein the force measuring sensors and the distance measuring sensors are coupled to the computing unit and the stamps are controllable by the computing unit and independently of each other and can travel at least essentially perpendicularly to the base area, and wherein the stamps can be manually positioned and fixed, independently of each other, substantially parallel in relation to the base area; wherein the computing unit is adapted for determining a deviation between an actual contour and a desired contour of the component by comparing the measured weight force of each force sensor with the theoretical weight force of the respective force sensor; wherein, if there are any deviations in the contour, a contour of the large-area flexible component is changed until all weight forces F m that are measured at the points of support substantially agree with the theoretical weight forces F g , and the desired contour of the large-area flexible component has been achieved.
