Abstract:
1. A method for bonding a first surface and a second surface by means of an interlayer, comprising the steps: a) providing a first item which has the first surface, b) providing flowable, solidifiable material for the interlayer, c) providing a second item which has the second surface, d) applying the material for the interlayer onto the first surface so that a circumferential bulge encircling the first surface is produced, wherein the interlayer is distributed from a center to an outside edge of the first surface and the circumferential bulge is an elevated area along the outside edge of the first surface, e) applying a vacuum around the first item and the second item, f) bringing the second surface of the second item into contact with the circumferential bulge so that a sealed-off cavity is produced, g) increasing the ambient pressure so that the cavity is eliminated without resulting in a stream of gas flowing into the cavity and h) increasing the viscosity of the material for the interlayer.
