Abstract
Inventia se refera la un procedeu de obtinere a fibrelor din materialele termoplastice care pot fi etirate cu ajutorul unor curenti gazosi respectiv un curent gazos si cel piutin un jet gazos, acesta din urma avînd o sectiune transversala mai mica decît cea a curentului si o energie cinetica pe o unitate de volum mai mare ca cea a curentului, în asa fel încît jetul sa întînleasca curentul, sa patrunda în acesta din urma, fara a-l traversa formînd o zona de intractiune unde se stabilesc miscari turbionare cu o structura regulata în care este condus filamentul de material termoplastic etirabil, filamentul fiind adus în contact cu jetul în zona situata între jet si curent înainte ca jetul sa patrunda în curent, curentul gazos combinat format de jet si curent fiind orientat de sus în jos urmînd o directie apropiata de verticala în planul diferit de jet si filament, jetul si curentul convergînd de o parte si de alta a fialmentului. Dispozitivul pentru realizarea procedeului, conform inventiei, este constituit dintr-un generator de curenti gazosi, un emitator de jeturi dirijate, astfel încît sa întînleasca curentul, cu o secsiune dreapta la punctul de întîmlire inferioara celei a curentului, o sursa de material etirabil din care materialul iese sub forma de filament, dispusa fata de orificiiile generatorului de curent, fiecare plan definit de fiecare din jeturi si filamentul corespunzator, orificiul de iesire al generatorului de curent si al jetului fiind situate de o parte si de alta a filamentului pe traiectoria jeturilor fiind plasate la mijloce de modificare si deviere a acestora.
