ABSTRACT:
Folding mandrels (11) of a folding turret (10) are in the form of elongate thin-walled hollow bodies and are susceptible to mechanical stress. The folding mandrels (11) are monitored by a monitoring unit (13) with inductive tracers (14, 15; 29, 30) as regards correct arrangement and shape. Any changes in the shape of the mandrels actuate an error signal which is is assigned to the respective folding mandrel (11). The tracers may be arranged on one side of the path of movement of the folding mandrels (11) at different distances thereto. Alternatively, tracers can be installed at equal distances on either side of the path of movement of the folding mandrels (11).
