Abstract
A method for encasing a body of an exhaust gas system with a housing which is wound around the body. Using a winding method, the body is placed in a loop formed by a belt-shaped conveyor element that can be driven in a conveyor device, wherein the conveyor element is seated against the outer casing face at a wrapping angle u of at least 270 degrees. Starting with a first edge, the metal strip is then introduced in a conveyor device between the body and the conveyor element, is drawn into the gap between the body and the conveyor element and is bent around the body until the body is encased at least twice by the metal strip.
Claims9
A winding device for encasing a body of an exhaust system with a metal strip as the housing, comprising:
- a) at least two parallel arranged side pieces and several axles and shafts mounted in the side pieces and able to rotate and situated perpendicular to the side pieces, wherein the side pieces and the axles and shafts form a machine housing,
- b) a belt-shaped conveyor element, which is mounted on the axles and shafts and can be driven in at least one of the directions of conveyance by at least one driving device of the winding device, provided on the shafts,
- c) between the side pieces, two deflection elements, arranged parallel to the axles, forming a gap running parallel to the axles, with the conveyor element mounted on them in sliding manner,
- d) a winding space beneath the gap, bounded by the axles and situated between the side pieces,
- e) wherein the belt-shaped conveyor element projects on either side of the gap beyond the two deflection elements into the winding space and forms a loop in the winding space, in which the body being wrapped can be placed.
