Patent ID: 8371838

Claim:
A device for placing a material layer onto a relief mould for producing composite materials, the device comprising: an elastically-reversibly deformable body, the elastically-reversibly deformable body comprising: a surface that is configured to alternately assume a deformed state and a non-deformed state and further configured to generate a retention force while in the deformed state that fixes the material layer onto the relief mould and that places the material layer onto the relief mould upon a cancellation of the retention force; a foam material that is configured to return the elastically-reversibly deformable body from the deformed state to the non-deformed state; and a surface relief of the surface in the non-deformed state that corresponds to the relief mould, the surface is configured to elastically deform under a pressure force so that the surface is substantially flat against the material layer in the deformed state, wherein the elastically-reversibly deformable body is arranged with the material layer that has been fixed to a corresponding surface of the relief mould so that a surface relief of the material layer conforms to the relief mould; a holder configured to build up the pressure force by pressing the elastically-reversibly deformable body onto the material layer deposited on a placement area and further configured to reduce the pressure force by lifting the surface from the placement area, which relaxes the surface into the non-deformed state, and imparts to the material layer a corresponding surface relief that corresponds to the relief mould; and a suction stream that is configured to generate the retention force on the material layer and temporarily fix the material layer to the surface.
