ABSTRACT:
The invention relates to a method of producing a telescopic cover using one single profile which is straight in the initial state and has a groove into which a flat material blank intended to form the top wall and the side walls is inserted. This material blank and the profile are then bent together to form the top wall and side walls, the outer strip of the profile being stretched in the region of the two bend lines without cracking to form a rounded outer contour.
