Summary
[edit]Description00016 Torchio a vite.jpg |
Italiano: La vite, o propriamente "il pane della vite", è un cilindro con filetto sporgente (verme) generato da un triangolo, o da un rettangolo, che si muove appoggiandosi con un lato sopra le successive generatrici, e con un vertice sui punti corrispondenti di un'elica. Tutti i punti del verme possono dunque considerarsi come appartenenti ad eliche di raggi diversi, ma dello stesso passo che si chiama "passo della vite". Al pane va congiunta la propria "madrevite", che si può considerare come lo stampo di una porzione del pane, talchè sarà munita internamente di un solco, che si riempirà in tutto del verme. Ora, se uno dei pezzi è fisso, l'altro non potrà muoversi, se non che girando attorno all'asse del cilindro, ed in pari tempo avanzandosi nella direzione di questo. Il più delle volte questa macchina si adopera per esercitare delle forti pressioni, ma trova altre applicazioni ben diverse. |
