Abstract: The invention relates to a method and a device for applying films (10) to interior wall sections of the bodywork (7) of a vehicle with the aid of an instrument or robot (6) comprising a multi-membered articulated arm (18, 19) and gripping elements (21) for the films. To reduce the mounting time, the robot (6) is driven through an opening (14) in the interior of the bodywork (7), the films (10) to be applied are transported by transport elements (11) to the vicinity of the interior or into the interior of the bodywork (7) and the delivered films (10) are taken from the transport elements by the robot (6) and its gripping elements (21) and are applied to the respective interior wall sections.
