  • Patent number: 12759089
    Abstract: A device for trimming and welding strip ends, in particular for use on laser welding devices or resistance welding machines, in which the strip ends to be joined are positioned at a distance from one another and are trimmed parallel to one another before welding by a mechanical cutting device, includes at least one heating device provided on the laser welding device for heating the actual welding region that can be positioned relative to at least one of the cutting regions of the strip ends to be joined before cutting and can be actuated in such a way that the cutting region is heated and at least one strip end can subsequently be cut in the heated state. A corresponding method is also described.

  • Publication number: 20030182981
    Abstract: In a die-side ejector device for presses, a stationary press die cooperates with a press ram on a press frame in order to shape a blank introduced into a bore of the press die. An ejector pin is displaceably provided in a bore in the press frame, said ejector pin being biased against an ejector lever which is pivotable by an actuator lever between a starting position and a final ejection position and which is supported, on its side facing away from the ejector pin in its starting position, on a pressure piece on the press frame.
