Abstract: A centering device for guiding a fastener or a drill during a setting operation. The centering device is arranged in or at a passage opening of a component, which forms a fastening point. The component can be a substantially flat metal part, in particular a lug or bracket for a façade element. The centering device is arranged at the plane of the back of the passage opening and includes a collar and connecting elements between the collar and the edge of the passage opening. The collar has a substantially flat to bead-like annular shape and is formed in the component. The central opening of the collar forms a centering seat for a fastener or drill during setting. A fastening arrangement has a component, centering device and matching screw. The screw forms a form fit via its lower head portion in the passage opening after completion of the setting process.

Abstract: An apparatus for mounting a piece of foil on a substrate comprises a holder for receiving a strip of foil which is wound up on a roll, a loop buffer, an alignment unit in which the strip of foil is guided between two parallel plates and is deflected at least twice, a feed unit for the intermittent feeding of the strip of foil and a cutting unit for cutting a piece of foil. The cutting unit comprises two blades which touch each other in a contact point in order to cut the piece of foil.

Abstract: A device for pressing on semiconductor chips situated on a substrate comprises a substrate support and a tool movable in relation to the substrate support in a predetermined movement direction, which has multiple pressing plungers mounted so that they are displaceable in the movement direction of the tool for pressing on the semiconductor chips. The tool has a pressure chamber to which compressed air may be applied. All pressing plungers are situated along a straight line. Each of the pressing plungers has a bar running perpendicularly to the movement direction of the tool and perpendicularly to the cited straight line on its end facing toward the pressure chamber. Pistons are situated in the area between the pressure chamber and the pressing plungers, which are displaceable in the movement direction of the tool. One side of the pistons is subjected to the pressure existing in the pressure chamber and the other side rests on one of the bars of the pressing plungers.
