Method and apparatus for applying self-adhesive protective sheeting to vehicle bodies
First Claim
1. Method for applying self-adhesive protective sheeting to surface parts of vehicle bodies, the protective sheeting being provided in at least one stock roll, said method comprising:
- drawing a measured sheeting piece from the stock roll by means of an application robot;
stretching said sheeting piece so that it is free of creases and with inherent stress;
in the stretched-out state of the sheeting piece, before the application of the sheeting, forming perforation lines in a first preselected position in the sheeting piece by means of an apparatus capable of being moved in a programmed manner and carrying a perforating tool;
said robot lowering the perforated sheeting piece in a second preselected position, onto a surface part of the body; and
pressing said sheeting piece down onto the said surface part so as to be free of creases and bubbles.

Abstract
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.
