• the angle of rotation is then so far that the display film 1b is lifted when turning further backwards (to the left in the picture), then the movement follows downwards, then forwards again, in the direction of the cover film 1a and then behind the cover film 1a, so far upwards until the setting is reached.
• the axes 68 then remain stationary for the time being and the setting device (not shown) travels from left to right (or vice versa) over the entire display device, which is composed of several modules.
• the motor then rotates the axes 68 clockwise and thus lowers the display film 1b down to the display position shown in FIG. 18, in which the deflected cover elements 1a disappear behind the associated display elements 1b.
• the desired displacement of the display i with respect to the cover film 1a and the lifting thereof from the cover film 1a are combined into one large rotary movement and accomplished by only one motor which can be rotated back and forth.
• the modules that can be lined up have a spacing that is smaller than half the width of the display elements 2b. It is therefore possible that, for example, the outermost web of the display film 1b (seen on the left or right from the front) lies on the outermost steel web of the neighboring module.
• the cover films 1a also overlap on the right and left with their webs and the corresponding webs of the cover film of the adjacent module.
• the cover film 1a and the display film 1b are therefore only attached to the top and bottom tube profi les 64 and 65 respectively, but not to the side. This is also sufficient because there are only tensile forces in direction 8 or in the opposite direction.
• the square tube profiles 69 in FIG. 8 at the top and bottom carry guides, not shown, in which the setting device, not shown, can be adjusted like a slide.
