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.

Abstract: The invention relates to a so-called spring cushion (5), for the ejection of moulded pieces (4) from a moulding tool (3), with a plunger (6), moving in a guide tube (9) within the moulding tool and loaded in the ejection direction (14) by means of a spring (15). According to the invention, the spring (15) is embodied as a draw spring, in particular as a spiral draw spring. Considerably longer service life can be achieved as draw springs do not have radial deflections on loading.

Abstract: The present invention relates to a device on a press and to a method for incrementally conveying workpieces in a longitudinal direction from a receiving station through at least one tooling station of the press with the aid of conveying means for the workpieces, which conveying means are moved back and forth in cycles and in synchrony with the movement of the press in the longitudinal direction, as well as in a transverse direction substantially perpendicular thereto in order to grip or release the workpieces. The conveying means are here moved in the longitudinal direction by means of an external drive unit which is merely synchronized with the movement of the press. The motor-powered external drive unit is mechanically coupled to the conveying means in such a way that the conveying means can be moved back and forth without reversing the rotation of the external drive unit.

Abstract: The invention relates to a method for producing lamella packets (e.g. 70) such as those used for adjustable steering columns in automobiles. According to the invention, at least one of the lamellae (e.g. 71) is provided with a collar (71.1) and is joined to another lamella (e.g. 72) so that the collar (71.1) of the first lamella (71) is supported against the other lamella (72) whereby defining the width (B) of a space between the lamellae (71, 72). Both lamellae (71, 72) are welded at at least one location of the collar (71.1). The welding is preferably carried out by resistance welding. In order to obtain defined ratios, the edge of the lamella collar (71.1) is preferably provided with projecting points (Z). The method is, among other things, advantageous in that the same material quality can be used for all lamellae (1–74).
