Abstract
An apparatus for retaining a package of laminations of an electromagnetic core in a device () for the production thereof that is mounted into a panel () arranged at a distance from a yoke () of said device () for the production of individual laminations () and mutual joining of same into a package (), wherein it comprises peripheral units like an aggregate for pressurized hydraulic oil, sensors, control unit and ejector. The apparatus of the invention is formed in a way that within said panel () a cylinder () is arranged co-axially with a sleeve () within said yoke (), said cylinder () housing a hydraulic piston () with a piston rod () with a coaxial drilled hole (), wherein on the top of said piston () adjacent to said sleeve () there is a pivotally mounted panel () that is simultaneously supported on said piston () by a spring () and said piston rod () is further led within said cylinder () at a distance by means of three mutually distant gaskets () in order to create two spaces () and () between said piston rod () and said cylinder () in that a central section () of said piston rod () is thinner and that both spaces () and () are provided with hydraulic connections () and () for an alternate supply of pressurized oil into one or another space () and ().
