Abstract
A method of producing a sintered body (1) having different cross-sections along a main axis (5), in particular a toothed-belt or chain wheel, by compression moulding a sintering powder in the direction of the main axis (5) and subsequent sintering. At least two partial bodies (6, 7), which can be form-fitted into each other in the direction of the main axis (5), are pressed from sintering powder, which partial bodies each form an axial portion of the sintered body (1) with different cross-sections, and that the separately pressed and possibly presintered partial bodies (6, 7) are jointly sintered after joining them together.
