Abstract: A radiator shutter for a motor vehicle for controlled engine ventilation, having a frame in which at least two louvres are mounted rotatably to pivot from a closed position to an open position. A motor which drives a single louvre is provided in or on the frame on an engine side of the frame. On the same side is a coupling element which synchronously transmits the rotation of the louvre to the other louvres. A locking disc is provided for each louvre on the mounting side of the frame facing away from the engine side of the frame, in the region of the mounting provided there for the louvres. The locking discs have a form which, if at least one of the locking discs does not rotate synchronously with all the other locking discs, blocks the rotational movement of the locking discs in a force-fitting and form-fitting manner.

Abstract: The invention relates to a method for the production of a rolled edge from an edge section (11) of a tube, wherein a flanging die is driven onto the edge section and flanges it into a roll. According to the invention, an initial area (14) of the edge section (11) is previously rolled in a positive fit manner by means of a forcibly controlled tool (30). This prevents buckling of the initial area (14), which has a controlled geometry as a result of rolling. The novel method is preferably used in the production of valve seats in so-called aerosol domes (10) for spray cans.
