A-35026/ESA/LCB Abstract of the Disclosure A coating system utilizing application under vacuum technology in which entrance and exit ports for the material to be coated are defined by a pair of horizontal gates and a pair of vertical gates at the inlet and outlet apertures of the coating chamber. A mounting arrangement at each port mounts the top vertical gate and the two horizontal gates in sliding relation with associated edges of the inlet and outlet apertures. Positioning arrange- ments are provided for each of the slidably mounted gates for setting an initial position of the associated gate, and each gate is provided with spring means for biasing that gate toward its initial position. A dimension sensing-adjusting arrangment is provided with a dimension sensing element mounted in the coating chamber by a mounting arrangement which enables the dimension-sensing element to detect strips of larger than normal thickness and automatically adjust the vertical position of the top vertical gate at the exit port to maintain clearance between the bottom edge of that gate and units of material passing through the exit port. In one embodiment, a masking element is provided between the entrance and exit ports to preclude application of coating material on preselected surface portions of material passing through the chamber.
