The beater consists of a rod (12) with a hub (15) at one end to which two wire loops (19,20) are fastened at right angles to one another. The hub is made by over-moulded from injected plastic, carried out with the two loops positioned horizontally in the mould in planes perpendicular to the axis of the rod. After the hub has been removed from the mould, which can be done in an axial direction, the two loops are pivoted so that they lie in line with the rod, and their crossing ends are then welded together. <IMAGE> |
