Abstract
A multiple tube processing coil for processing two or more elements that are ring-shaped in the processing area thereof, are made of an electrically conductive material and each element tightly encompasses a pressing zone of a mating piece. The multiple tube processing coil includes a pulsed power source and an electric conductor that is connected thereto, entirely surrounds the elements in the processing area thereof and is U-shaped. The two legs of the U-shape are each provided, across from one another, with at least one concavity. The internal edges of the two opposite concavities jointly have a shape that is complementary to the external edge of the cross-section of the elements and is equidistantly enlarged. At least the concavities on the internal faces of the two legs of the U-shape are covered with an electrically insulating layer.
