Abstract
The invention concerns on the one hand a gripping device (10), particularly for automatic printing and/or inserting machines, with a first and second gripping element (22, 24) of which at least one gripping element (22) can be moved relative to the other gripping element (24) to grab sheet-like materials such as printed pages as well as with a measuring device (42) for the recording of at least one position of the gripping elements (22, 24) towards each other, and on the other hand a method for recording a relative position of gripping elements within a gripping device. In order to be able to adjust the gripping device to different sheet thicknesses as well as to improve proneness to malfunctions, the system provides for the measuring device (42) to have a transmitter (52) and a sensor (54) that is allocated to it for the continuous recording of the relative position of the gripping elements (22, 24) towards each other, with the transmitter (52) being arranged in a moveable gripping element (22) and the sensor (54) in the fixed gripping element (24), or vice versa. The invention provides for the position of the gripping elements towards each other to be continuously recorded, for a signal with different signal values to be generated in accordance with a number of sheet-like materials grabbed between the gripping elements and/or for the signal values to be compared to target values and for an error message to be generated in the case of a deviation.
