Abstract

The invention relates to a method for producing a windshield (10), comprising at least the following method steps: (a) providing an outer pane (1) and an inner pane (2), (b) heating the outer pane (1) and the inner pane (2) to at least their softening temperature, (c) jointly bending the outer pane (1) and the inner pane (2) or individually bending the outer pane (1) and the inner pane (2), (d) cooling the outer pane (1) and the inner pane (2), (e) laminating the outer pane (1) and the inner pane (2) with the insertion of a thermoplastic interlayer (3) to form a composite pane (10), in which step d) the outer pane (1) and / or the inner pane (2) is cooled in a first surface region (X1) at a first cooling rate (A1), and in step d) the outer pane (1) and / or the inner pane (2) is cooled in a second surface region (X2) at a second cooling rate (A2). And the outer pane (1) and / or the inner pane (2) is cooled in the second surface region (X2) at a second cooling rate (A2), wherein the absolute value of the first cooling rate (A1) is greater than the absolute value of the second cooling rate (A2).
