Taping down tool and method for the automated, series application of adhesive tape, in particular on surface parts of vehicle bodies. The taping down tool comprises a mount for an adhesive-tape roll containing adhesive tape to be applied, an application roller for the application of adhesive tape, which has been pulled off from the adhesive-tape roll, and a holding device, which is arranged upstream of the application roller, for holding ready adhesive tape, which has been pulled off from the adhesive-tape roll, between two application processes, the holding device moreover serving for the pressing-on of held-ready adhesive tape on the surface to be covered, so as to initiate an application process, and, after a forwards movement of the taping down tool, adhesive tape, which has been pressed on by the holding device, being taken over by the application roller which can be extended essentially perpendicular with respect to the plane of the pressed-on adhesive tape in the direction of the adhesive tape and is used for the force-controlled pressing-on of the adhesive tape.

In a method and apparatus for automatically applying self-adhesive protective sheeting to surface parts of vehicle bodies, a specific rectangular piece of protective sheeting in the form of stock roll is grasped on its non-adhesive side, using a robot-controlled tentering frame with suction legs, is drawn off and is cut off. Before the sheeting blank is laid on to the body, in the freely stretched-out state tear-off lines are perforated, preferably from the non-adhesive sheeting side, in the region of accessory parts by means of a perforating device guided along definite contour lines. Thereafter the protective sheeting, which is thus prepared and stretched out so as to be free of creases in the tentering frame, is lowered in the correct position onto the associated part by the handling robot and laid onto the surface part so as to be free of bubbles. The sheetings are subsequently pressed down in a brushing manner under an elastic brushing bar extending over the entire vehicle width. In the region of glued-over gaps in the vehicle body surface, the protective sheeting is severed and the cut edges are pressed down. In the region of accessory parts, protective sheeting parts are drawn off along the perforated tearing lines and openings are thus made in said regions in a manner appropriate for assembly.

Device and method for changing film rolls, with apparatus for holding a first film roll in a working position in which film can be pulled off and separated from the film roll as desired, and holding a second film roll in a standby position. The second film roll can be moved from the standby position into the working position, with the first film roll being removable from the working position by moving the second film roll.
