Abstract: For cutting in sequence from a strip of sheet metal all the plates of a transformer core which are interleaved with separate yoke and leg plates, a number of shears are placed obliquely in relation to the feeding direction of the metal strip to cut off plates from the metal strip, along with a number of punches to make notches in the yoke plates for connection of the central leg to the yoke. A number of stops movable into and out of the path of the strip are provided to stop the strip in proper position before each cutting step.
