Abstract: An extrusion die (1) with a calibrated exit orifice (6) for extruding extruded sections (3, 3', 3") of different profile cross-sections onto a glazing or glass plate (2) is provided with an obturating slide (22) movably positioned in front of the calibrate exit orifice (6) through which the die cross-section can be adjusted. The slide (22) is operated by a pneumatic jack (16).

Abstract: A method of shaping an extruded section of polymer directly onto the surface edges of a glazing or glass plate. In one embodiment, a rotatable plate member having a plurality of calibrated die cross sections is placed in front of the exit orifice of an extrusion die. The plate member is rotated to obtain, an extruded section having different profile cross sections and the flow rate of the polymer through the die is controlled in response to the position of the plate member so that the amount of polymer being fed corresponds to the respective profile section being extruded. In another embodiment, an obturating slide member is placed in front of an extrusion die exit orifice sized to correspond to the largest desired profile cross section. To produce abrupt changes in profile cross section, the slide is moved quickly at predetermined locations along the path of the extrusion die. To produce a continuous transition between profile sections, the slide is moved slowly during extrusion.

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.
