Kern eines Transformators mit geschichteten Blechen sowie eine Vorrichtung und ein Verfahren zur Herstellung der Bleche

摘要

In order to shape more precisely a core (7), in particular for a transformer, so that its cross-section has a shape which is closer to a predetermined shape, the core metal sheets (9 to 9e) are produced from a sheet metal strip (3a to 3a) with a predetermined lateral profile (5a to 5e). The core metal sheets (9 to 9e) thus do not have a constant width. A core (7) produced according to this process is disclosed, as well as a device (17) for producing the sheet metal strip (3a to 3e) and a process for operating the device (17).
