The exposure frame is a mobile equipment, on a wheel support allowing the movement of the frame in a position as close as necessary for the exposure; the support can be blocked in the end position. The frame is rotating and allows the easy access of the operator to fix the film in the horizontal position and to make the exposure, rotating the frame in the vertical position.
The foil which insure the contact of the film with the mesh is a flexible rubber foil; when the vacuum is applied, the foil is uniformly pressed against the glass of the frame, on the whole surface.
The control panel is attached to the frame and includes the ON/OFF switch and the control for the vacuum and the intake valve for pressure equalizing
