Abstract

A process for producing a laminated glass pane made up of a base pane, a first laminating film, a coated polymer film with a coating, a second laminating film, and a top pane having at least one sensor window is described. The process has steps a) to d), wherein a) the coated polymer film with the coating is tensioned pointing upward by way of a vacuum table, b) at least one region from which the coating is removed is produced on the coated polymer film by means of laser treatment, c) the first laminating film is arranged on the base pane, the coated polymer film is arranged on the first laminating film, the second laminating film is arranged on the coated polymer film and the top pane is arranged on the second laminating film, and d) the arrangement is autoclaved. The region from which the coating is removed is produced by way of glass plates with which the vacuum table is equipped.
