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.

Process and device for coating a glass sheet with a flexible film

Process for laminating a glass or plastic sheet with a flexible film

A calendering device has a plurality of pressure rollers and an opposing plurality of counterpressure rollers, each rotatably mounted on a piston rod movable in a direction for permitting the pressure rollers and counterpressure rollers to approach one another to calender a product. The pistons of the piston rods are mounted within pneumatic casings and are moved by a diaphragm within the pneumatic casings. There is no contact between the pistons and the walls of the pneumatic casings, thereby reducing the frictional resistance to the movement of the rollers. Means are provided for equalizing the pressure applied to a roller and its corresponding counter roller. Separate pneumatic casings and diaphragms may be provided for each piston rod, or several of the pressure rollers or countepressure rollers may be moved by a single diaphragm, which can be in the form of an elongated hose. In the case of the provision of individual pneumatic casings for each roller, pressure regulating means can be provided for each pair of a pressure roller and its corresponding counterpressure roller.
