Abstract

Si propone un procedimento per la fabbricazione di un listello tergitore di forma allungata, in materiale elastico, per tergicristalli di autoveicoli. Il listello tergitore trattenuto da un supporto su un listello dorsale, è dotato di un canale longitudinale atto ad accogliere una guida elastica di irrigidimento e circondato su tutti i lati, nel senso della longitudine, da pareti del listello dorsale, e il procedimento per la produzione di un tale listello tergitore comprende le seguenti operazioni: nello stato iniziale, deformabile plasticamente, il listello viene estruso da materiale in uscita attraverso un ugello di istruzione laddove il canale longitudinale presente nel listello dorsale all'uscita dall'ugello di estrusione in un primo momento è aperto lungo una fenditura longitudinale che poi - mediante accostamento l'uno all'altro dei tratti a parete del canale longitudinale formanti i bordi della fenditura - si chiude nello stato ancora molle, cosicché detti tratti a parete si uniscono l'uno all'altro e il canale longitudinale si chiude tutt'intorno in senso longitudinale allorché il listello tergitore è indurito.(Figura 1).
