发明名称 WRITING POINT
摘要 <p>A method for the production of a writing point for liquid ink by utilizing a tube (5) of small internal diameter and a writing point which is produced thereby are proposed. In such a case, axially extending ink channels (3) are provided in the internal wall of the fixed tube (5) having an internal diameter which substantially corresponds to the diameter of a ball (1), said channels (3) extending to the free end of the tube (5) and being spaced from one another. A circumferential, annular recess (9) is formed in the tube (5) at a distance from the free end of said tube, and the ball (1) is inserted into the free end until it abuts against the recess (9). Subsequently, the free edge of the tube (5) is inwardly flanged, and a substantially cylindrical ink conductor (4) is inserted into the remote end of the tube and partially overlapped by the ink channels (3).</p>
