Abstract
For coating a glass sheet (1) with a flexible transparent film (2) glass sheet (1) and film (2) are brought together at an acute angle .alpha. and are continuously moved together. In the area ahead of the contact of film (2) with glass sheet (1) a continuously movable hollow space (8) is created with the help of a slot nozzle (3) which is in sliding contact on the one side with glass sheet (1) and on the other side with film (2). Air is continuously sucked from this hollow space (8) with the help of slot nozzle (3). By the resulting pressure difference acting on film (2), film (2) is preliminarily bonded to glass sheet (1). This preliminary bonding is followed by a final bonding by use of increased temperature and increased pressure.
