Abstract

Αποκαλύπτονται συσκευή και μέθοδος για σχηματισμό στρωμένων με αέρα ινωδών αντικειμένων. Παρέχεται συσκευή στρώσεως με αέρα η οποία επιτρέπει την αποϊνοποίηση τουλάχιστον δύο τύπων ινώδους υλικού και τη μεταφορά αυτών σε μια μόνο συσκευή στρώσεως με αέρα. Σε μια κατά μεγίστη προτίμηση ενσωμάτωση παρέχεται ένα τύμπανο στρώσεως με αέρα τύπου τυμπάνου το οποίο έχει κοιλότητες αποθέσεως. Με έλεγχο της ροής αέρα και διαφορικής πιέσεως, επιτυγχάνεται επιλεκτική τοποθέτηση εκάστου τύπου ινώδους υλικού εντός κοιλότητας. Επίσης αποκαλύπτονται βελτιωμένες κοιλότητες αποθέσεως οι οποίες επιτρέπουν το στρώσιμο με αέρα σε πολλά υλικά και τη συγκράτηση αυτών στη θέση των με παροχή διάτρητης επιφάνειας τουλάχιστο σε ένα τμήμα του πλευρικού τοιχώματος κοιλότητας. Κατά μεγίστη προτίμηση, σχηματίζεται ένα στρώμα από υδροφιλική ίνα και ένα στρώμα από απορροφητική ίνα αποτίθεται εντός του πρώτου στρώματος η παρούσα εφεύρεση επιτρέπει ένα σαφή διαχωρισμό μεταξύ των τύπων ίνας. Επίσης αποκαλύπτεται βελτιωμένη συσκευή για αφαίρεση στρωμένων με αέρα αντικειμένων από κοιλότητες αποθέσεως, με χρησιμοποίηση ελεγχόμενου με ακρίβεια ρεύματος αέρα. Επισης αποκαλύπτονται βελτιωμένες μέθοδοι κατασκευής αντικειμένων στρωμένων με αέρα με ρύθμιση παραμέτρων διαδικασίας και με χρησιμοποίηση της βελτιωμένης συσκευής της παρούσας εφευρέσεως. ω
