Abstract
When a thermoplastic spacer is applied to a glass pane in the production of insulating glass panes, the nozzle from which the plastic with the desired cross sectional shape is extruded along the edge of the glass pane. The speed with which the plastic is applied along the edge of the glass pane is chosen depending on the temperature of the plastic. Here, for a stipulated temperature setpoint the speed with which the plastic is applied along the edge of the glass pane is stipulated. If the temperature increases, the speed is increased; conversely, when the temperature drops below the setpoint, the speed with which the plastic is applied along the edge of the glass pane is reduced. This ensures that the correct amount of thermoplastic is always extruded onto the glass pane and a spacer with a uniform cross section is obtained.
