Abstract: Disclosed are a method and device for sealing insulated glass blanks, wherein the insulated glass blank is moved substantially continuously through a sealing station. When sections of the edge joint of the insulated glass blank that are oriented transverse or oblique to the conveying direction are filled with sealing mass exiting from a filling nozzle, the filling nozzle is likewise moved in the conveying direction. When sealing mass is introduced from the filling nozzle into sections of the insulated glass blank that are parallel to the conveying direction, the filling nozzle is not moved in the conveying direction or is moved in the conveying direction at a velocity V2 deviating from the velocity V1 at which the insulated glass blank is moved.

Abstract: An apparatus for depositing a material layer on a sample inside a vacuum chamber comprises a sample stage (100) for arranging at least one sample (103a, 103b, 103c, 103d); an evaporation source (101, 201), connected to a current source, for a thread-shaped evaporation material (102, 202); a quartz oscillator (105) for measuring the deposited material layer thickness; and an evaluation device (113) associated with the oscillator (105). An electronic control system (112) associated with the evaporation source (101, 201) is configured to deliver electric current in the form of at least two current pulses having a pulse length less than or equal to 1 s. The evaluation device (113) takes into account transient decay behavior of the oscillator (105) immediately after a current pulse to derive the material layer thickness deposited after each pulse. The invention further relates to a method that can be carried out using said apparatus.
