A screen drum and a method for its manufacture is disclosed wherein the screen drum comprises at least two cylindrical screen members spaced apart, between which a stiffening ring is disposed. The stiffening ring has two cylindrical surfaces which guide the ends of the cylindrical screen members, and a projecting part between them. The cylindrical screen members and the stiffening ring are attached to each other by a weld joint connecting the projecting part of the stiffening ring and the ends of the cylindrical screen members and filling the gap between them. |
