Layer assembly comprising mineral material and glass and method for the production thereof

A method for producing a layered composite material, wherein said layered composite material comprises a substrate, a cover layer and an adhesive layer disposed between the substrate and the cover layer and the adhesive layer at least partially contacts the substrate and the cover layer, including the steps of:

• A) providing an assembly which comprises a substrate and a cover layer, wherein
• the substrate comprises a first substrate side with an upper substrate edge when viewed in the vertical direction, a lower substrate edge when viewed in the vertical direction, a first substrate side edge and a second substrate side edge disposed opposite to the first substrate side edge;
• the cover layer comprises a first cover layer side with an upper cover layer edge when viewed in the vertical direction, a lower cover layer edge when viewed in the vertical direction, a first cover layer side edge and a second cover layer side edge disposed opposite to the first cover layer side edge;
• the first substrate side and the first cover layer side face to each other in the assembly under an angle α and a bisector of the angle α is formed;
• the upper substrate edge and the upper cover layer edge are disposed opposite to each other in the assembly;
• the lower substrate edge and the lower cover layer edge are disposed opposite to each other in the assembly;
• the first substrate side edge and the first cover layer side edge are disposed opposite to each other in the assembly;
• the second substrate side edge and the second cover layer side edge are disposed opposite to each other in the assembly;
• in the assembly the distance between the upper substrate edge and the upper cover layer edge is larger than the distance between the lower substrate edge and the lower cover layer edge;
• in the assembly a first seal is provided between the lower substrate edge and the lower cover layer edge which prevents the escape of fluids between the lower substrate edge and the lower cover layer edge;
• in the assembly a second seal is provided between the first substrate side edge and the first cover layer side edge which prevents the escape of fluids between the first substrate side edge and the first cover layer side edge;
• in the assembly a third seal is provided between the second substrate side edge and the second cover layer side edge which prevents the escape of fluids between the second substrate side edge and the second cover layer side edge;
• such that the assembly forms a one side open container for receiving fluids and further a curable adhesive is provided in said container;
• B) pivoting the substrate and the cover layer towards each other such that the distance between the upper substrate edge and the upper cover layer edge decreases and the adhesive is moved towards the upper substrate edge and the upper cover layer edge,
• wherein step B) is carried out such that during at least a part of step B) the bisector of the angle α with respect to the vertical is in the range of ≧−45° to ≦45°.
