A. W. Faber-Castell, Stein Writing wick for fountain pens

The innovation concerns a writing wick for fountain pens, which are preferably used for marking, labeling, painting and also for writing.

In fountain pens, felt wicks are usually used as the writing element used, which on the one hand absorb the color liquid well due to their absorbency, but on the other hand Due to its softness, it also releases the color liquid well onto the surface to be written on.

With these felt wicks, however, you could not achieve fine lines or writing, because the felt through the Softening and swelling in the color liquid soon lost its point or edge and diverged like a broom. It has therefore been proposed for fountain pens to use bundled writing wicks instead of felt wicks Use plastic fibers that are held as tightly as possible in a socket. But also this kind of Writing wicks could not prevail for fine lines, because on the one hand the socket up to the front The writing tip would have to be sufficient to ensure the shape of the tip, and on the other hand a sufficiently large one Diameter would be required to bring about the parablastic fluid.

It has therefore also been suggested for fountain pens To use writing wicks made of synthetic fibers, where the plastic fibers lying next to one another are glued or even welded to one another with plastic adhesives. But these writing wicks had, as a result of the intimate connection of the elongated ones lying close to one another Synthetic fibers have too little capillary action, so that they do not contain sufficient quantities of parabolic fluid Could bring writing tip.

All of these proposals have therefore not been suitable for creating a fountain pen with a writing wick, the one has a sufficiently firm and at the same time fine point, which makes it possible to achieve thin lettering.

The innovation has now set itself the task of a writing wick to create, which has a high stability of the writing tip with good capillary conductivity. Achieved this is made possible by the fact that the writing wick is made from crimped

Synthetic fibers are made, which are mutually well matted by brushing. Subsequent soaking of the felted fiber wick in a plastic adhesive (ζ. B-. Melamine resin) and subsequent centrifugation and hardening in a mold or nozzle with heat treatment (at around 200 ° to 250 ⁰ C) creates a writing wick that meets all the requirements of a fine writing wick for fountain pens.

In the drawing, such a wick is shown schematically in its structure.

It shows:

1 shows a longitudinal section through the plastic fiber writing wick,

FIG. 2 shows a cross section through the object of FIG. 1 and

3 shows such a plastic fiber writing wick in one Fountain pen inserted.

The writing wick according to FIGS. 1 and 2 consists of crimped synthetic fibers 1 which are felted in the manner described above and are glued, whereby correspondingly large pores are formed, which a good absorption and forwarding of the Ensure color liquid. As a result of the good matting and bonding or welding of the crimped plastic fibers 1, a solid framework is achieved, which is a grinding the tip 1 allows a sharp cone tip or a corresponding cutting edge. A ventilation groove 3 is formed or ground in in a known manner along the side of the writing wick.

In Fig. 3, the front part of a pen is with shown a writing wick according to the innovation. In the shaft 6 a metal or plastic sleeve 5 is used, in which the writing wick D with the ground ventilation groove 3 is pressed in. In the shaft 6 is located the filler 7, which consists of a loose fiber material and fills the color liquid container as completely as possible.

Since the writing wick D according to the invention is very porous with great strength, there is good contact with the filler body guaranteed to the writing wick D and a more favorable writing property available.
