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

What is claimed is:

1. A method of applying a film element to at least one of a shaping tool or a component, the method comprising the steps of:
providing a frame in frame device comprising:
an outer bearing frame;
a support frame displaceably arranged on and/or within said outer bearing frame;
a plurality of gripper units arranged within the support frame, the plurality of gripper units configured to be selectively displaced relative to the support frame to stretch and/or shape the film element; and
an active gripper on each of the gripper units, the active grippers each configured to move relative to its gripper unit and to grip the film element; and

moving the active grippers relative to the gripper units to apply the film element to at least one of the shaping tool or the component.

2. The method according to claim 1 , further comprising the steps of:
moving a plane of the film element relative to the shaping tool or the component.

3. The method according to claim 1 , further comprising:
replacing the support frame with another support frame.

4. The method according to claim 1 , further comprising independently controlling at least one of the gripper unit or the active grippers.

5. The method according to claim 1 , further comprising the steps of shifting at least one of the gripper unit and active gripper in space as a function of a spatial position or a spatial displacement of the support frame.

6. The method according to claim 1 , further comprising controlling at least one of the gripper units or active grippers as a function of a film material of the film element.

7. The method according to claim 1 , further comprising the steps of actively controlling the gripper units and active gripper to pre-stretch the film element.

8. The method according to claim 1 , further comprising shifting support frame in space as a function of a spatial displacement of at least one of the gripper unit or active gripper.

9. The method according to claim 2 , wherein moving the plane of the film element occurs while displacing at least one of the gripper unit or the active gripper.

10. The method according to claim 2 further comprising, displacing at least one of the gripper unit or the active gripper after moving the plane of the film element.
