Definizione del messaggio (Alimentatore)

Per lo stesso tipo di problema vennero prodotte altre soluzioni, come la creazione di opportune tasche laterali a fianco del canale (come nello ''[[Spoon feed]]'' di [[Waterman]]). Negli anni poi è proseguito sviluppo di meccanismi che, o con la presenza di incisioni in forme più o meno frastagliate della parte esterna come nello ''[[Spear-head]]'' di [[Parker]] o le varianti del [[comb feed]] creato da ''August Eberstein'' (brevetto {{Cite patent|US|750271)}}) come il [[Ladder feed]] della [[Swan]], o con la realizzazione alette, sacche, incisioni, canali ed altre configurazioni, consentissero all'eventuale inchiostro in eccesso di accumularsi opportunamente nelle varie pieghe, ed evitare accumuli pericolosi sul pennino, in particolare per compensare gli sbalzi di pressione dovuti all'aria presente nel serbatoio, problema diventato ancora più rilevante con l'affermarsi dei viaggi aerei.

TraduzioneOther solutions were produced for the same type of problem, such as the creation of appropriate side pockets next to the channel (as in the ''[[Spoon feed]]'' of [[Waterman]]). Over the years, the development of mechanisms has continued, either with the presence of engravings in more or less jagged shapes of the external part, as in the [[Parker]] ''[[Spear-head]]'' or in the variants of the [[comb feed]] created by ''August Eberstein'' ({{Cite patent|US|750271)}}) such as the [[Swan]] ''[[Ladder feed]]'', or with the realization of fins, bags, engravings, channels and other configurations, to allow any excess ink to accumulate properly in the various folds, and avoid dangerous accumulations on the nib, in particular to compensate for pressure changes due to air in the tank, a problem that has become even more significant with the emergence of air travel.
