Method and device for producing an edgefold

A method to produce an edgefold on a component, which comprises a support and a cover layer, the method comprising:

• providing a non-inflatable elastic body,
• providing the component, wherein the support has a front side and a back side and the cover layer is laminated to the front side of the support, wherein the support has an opening completely defined by an edge of the support and a recess in the back side surrounding the edge, and wherein the cover layer comprises a protrusion which overlies a portion of the opening defined by the edge of the support,
• deforming the non-inflatable elastic body, wherein the deforming of the non-inflatable elastic body forms a bulge in the non-inflatable elastic body which is passable through the opening,
• after the bulge is formed in the non-inflatable elastic body, moving the non-inflatable elastic body and/or the component relative to each other, wherein the bulge in the non-inflatable elastic body contacts the protrusion of the cover layer which overlies the portion of the opening and moves the protrusion towards the back side of the support, and the non-inflatable elastic body moves through the opening, as the non-inflatable elastic body and/or the component move relative to each other,
• after the bulge in the non-inflatable elastic body contacts the protrusion of the cover layer which overlies the portion of the opening and moves the protrusion towards the back side of the support, further deforming the non-inflatable elastic body, wherein the bulge in the non-inflatable elastic body increases and, as the bulge increases, the bulge further moves the protrusion towards the back side of the support wherein the protrusion enters the recess and contacts the back side of the support in the recess surrounding the edge wherein the protrusion forms the edgefold over the edge of the support defining the opening.
