Packaging machine and method for adjusting multiple machine elements on a packaging machine

A method for adjusting multiple machine elements on a packaging machine, wherein the position of each machine element is changeable by driving an assigned spindle in a rotary manner, and wherein a position measuring device by means of which the position of the assigned spindle is measurable is present on each spindle, and wherein the measurement data of the different position measuring devices are transmittable to a control, the method comprising the following method steps:

• a) coupling an adjusting device to a spindle, wherein the spindle is drivable in a rotary manner by driving the adjusting device;
• b) driving the adjusting device with a predefined detection adjusting movement, wherein the spindle is adjusted along a detection adjustment path by means of the predefined detection adjusting movement;
• c) detecting the spindle, for which the adjustment along the detection adjustment path has been transmitted, via the control;
• d) determining the deviation between the measured actual value (αist) and a predetermined target value (αsol1) of the position of the spindle via the control;
• e) via the control, generating an adjustment signal for controlling the adjusting device when adjusting the spindle from the actual position (αist) into the target position (αsol1).
