- FIG. 2a shows a sensor 16 for detecting the leading edge of the Guts 10 shown.
- the signals detected by the sensors are in this case transmitted to a control device for controlling the rotary devices 1, 2 and in particular for controlling the motors 3a, 3b; 4a, 4b, which drive the rotating means of the first rotating means 1 and the second rotating means 2, respectively.
- a control device for controlling the rotary devices 1, 2 and in particular for controlling the motors 3a, 3b; 4a, 4b, which drive the rotating means of the first rotating means 1 and the second rotating means 2, respectively.
- the entire turning process has been divided into two sub-steps, namely in a first sub-step in the first rotating device 1 and a second sub-step in the second rotating device 2. It is also possible to divide the overall turning process into more than two sub-steps and for this purpose provide further rotating devices, which then connect in the transport direction x to the second rotary device 2 and the subsequent transport device 18.
