| 摘要 |
The inventive writing nib comprises a section of a longitudinal, consistent element consisting of a very porous material, with at least one first end configured as a writing head. The pores and/or capillaries of said material are blocked for a limited thickness (e), especially 0.01 to 1mm, on the longitudinal outer periphery of the longitudinal element, with the exception of the first end that forms the writing head. According to a first embodiment, said pores/capillaries are blocked with a plugging agent (15) by means of continuous impregnation of the longitudinal element (2) with a plugging bath (6) and hardening of the agent. According to a second embodiment, the nib is made up of sintered microbeads and the pores/capillaries are blocked by means of localised thermofusion of said microbeads.
