Abstract:
1. A method for encasing a body of an exhaust gas system with a housing, wherein the body has an outer envelope surface arranged about its axis of rotation with a circumference and the housing is formed from at least one single-piece metal strip with a width and a length, comprising the following process steps: a) placing the body in a loop formed by a belt-shaped conveyor element that can be driven in at least one conveyor device, wherein the conveyor element is seated against the outer envelope surface at a wrapping angle of at least 270 degrees, b) starting with a first edge, the metal strip is introduced in a conveyor device between the body and the conveyor element, c) drawing the metal strip into a gap between the body and the conveyor element at least by the movement of the conveyor element in a conveyor device and at the same time it is wound around the body with the drawn-in portion of the metal strip, d) operating the conveyor element until the body is encased at least twice by the metal strip.
