摘要

The method involves removing a slim body from a position on a float, while maintaining a state of compound. A treatment device (1) is guided over an impression device (13) of the slim body. The treatment device is moved to an intermediate position between the former position and another position on a driving surface of the slim body, where the intermediate position is remote from the former position. An intermediate section is linked to a top of an initial section. An independent claim is also included for a combination of treatment device and slim body, comprising a mobile system.
