Abstract

The aim of the invention is to further develop conventional devices for stretching and/or shaping and/or applying a lamination of a film element. This aim is achieved, according to the invention, by a device for stretching and/or shaping and/or applying a lamination of a film element, which device comprises a support frame for gripping the film element relative to a shaping tool or to a component to be laminated, and having grippers for gripping the film element, which are mounted so as to be movable relative to the support frame, said device being characterized in that grippers are arranged in a multi-axially adjustable manner relative to the support frame in order to adapt the film element more precisely to a contour of the shaping tool or of the component to be laminated.

First claim

The invention claimed is:

1. A frame in frame device for at least one of stretching, shaping or applying a film element to at least one of a component or a shaping tool, the device comprising:
an outer bearing frame;
a support frame configured to stretch, shape or apply the film element to the at least one of the component or the shaping tool and arranged within the outer bearing frame such that the support frame is at least one of monoaxially and multiaxially adjustable with respect to the outer bearing frame;
a plurality of gripper units configured to move relative to the support frame to stretch or shape the film element, the plurality of gripper units each comprising an active gripper configured to grip the film element and to translate its position relative to its gripper unit; and
wherein each of the active grippers are arranged to move relative to the gripper units so as to apply the film element to the at least one of the component or the shaping tool.

2. The device according to claim 1 , wherein:
the film element defines a plane which is displaceable with respect to a bearing frame part plane defined by the outer bearing frame part; and
the outer bearing frame is further configured for supporting the support frame.

3. The device according to claim 1 , wherein the support frame is adjustable in space with respect to the outer bearing frame part with at least one and up to six degrees of freedom.

4. The device according to claim 1 , wherein the active grippers are adjustable in space with respect to at least one of the support frame and the outer bearing frame part with at least two and up to six degrees of freedom.

5. The device according to claim 1 , wherein
the active grippers and gripper units are supported by the support frame, and
the support frame is arranged so that it can be at least one of rotated or translated in space.

6. The device according to claim 1 , wherein the active grippers are configured to be actively and individually controllable.

7. The device according to claim 1 , wherein the active grippers are configured to be controlled with individual timing.

8. The device according to claim 1 , wherein the active grippers are configured to be tilted with respect to a plane defined by the film element.

9. The device according to claim 1 , wherein the active grippers are configured to be rotated with respect to a plane defined by the film element.

10. The device according to claim 1 , wherein the active grippers are configured to be individually adjustable in height.

11. The device according to claim 1 , wherein the active grippers are configured to be at least one of accelerated or displaced at individual velocities.

12. The device according to claim 1 , wherein gripping forces created by means of the active grippers are configured to be individually created and changed.

13. The device according to claim 1 , further comprising a plurality of adjusting units configured for spatially adjusting the gripper units and/or the support frame.

14. The device according to claim 1 , further comprising electric drive motors arranged for driving at least one of the gripper or the support frame.

15. The device according to claim 14 , wherein the electric drive motors are arranged at the support frame.
