Abstract
The nib is constituted by a segment of a coherent, elongate element of high porosity material, with at least a first end shaped to form a writing tip. The pores and/or capillaries of said material are blocked over a limited thickness e in particular in the range 0.01 mm to 1 mm, at the longitudinal outer periphery of the elongate element, with the exception of the first end forming a writing tip. In a first variant, blocking is obtained by a sealing agent and performed by continuously impregnating the elongate element with a sealing bath, and setting the agent. In a second variant, the nib is constituted by sintered microbeads and blocking is obtained by localized hot-melting of the microbeads.
