Abstract (en)
[origin: DE19807981C1] Two spinning rotors (1,2) within the two-for-one twister produce feed yarns (F1,F2) which pass through a hollow spindle (11) and flier arm (3) to give a twisted two-ply yarn (F3). The yarn balloon passes directly through the pneumatically conveyed fiber feed from feed channels (4.1,4.2) in the annular space (10). Suction (L3) is applied through the hollow drive shaft (23) and induces an airflow across the annular space (10). Annular seals (14.1,14.2) and a cover (12.4) prevent air bypassing the feed duct (6.1).
