Abstract

A method for fabricating a choke wherein the air gap provided with an insert can be adjusted by core portions displaceable relative to one another. The relatively displaceable core portions are clamped between a floor with upstanding side edges and a resilient hood having sidewalls, the hood being displaceable towards the floor. After adjusting the desired air gap the sidewalls of the hood are fastened as by welding with the side edges of the floor, so that the air gap insert is continuously maintained under a constant stress or load.
