The invention provides an image processing method. At least one of the profiles facing the other profile comprises pointed andor sharp-edge bounded visible surface that is outwardly visible in the assembly position, which is formed by an at least regionally overlapping arrangement of the first and second profile. Accordingly, the plurality of the turbo streams can be transmitted far more easily. A vent is not opened until the operating section is opened, and closing section of opening and closing hole is provided so that the opening and closing hole may not be not clogged after being opened.
