- FIG. 6 shows a further possibility of defining an image section 50 with which the absence of a roll bar 26 can be detected.
- corresponding image section 50 extends here over a correspondingly larger Extension transverse to the direction 52 of the roll bar carpet 22a.
- a triggering signal is generated only after passing a predetermined number of characteristic components, for example, after passing five rolling rods 26, with the shutter 42.
- a predetermined number of characteristic components for example, after passing five rolling rods 26, with the shutter 42.
- an image 46 is detected.
- the image section is so large that a corresponding number of the to be detected
- Components for example, five rolling rods 26, are detected simultaneously. Each of the component to be detected is thus recorded only once each pass of the roll bar carpet 22. In this way, a total of one processing time can be reduced.
- control / evaluation devices used for example the control / evaluation devices 40, the central control device 60 and any other control / evaluation devices, may be implemented as separate units or at least partially combined and / or common components realized.
