The invention is directed to a ring spinning device (1) for making of a stretch yarn (28), comprising a drafting arrangement (2). The drafting arrangement (2) comprises a pair of entry rollers (3, 4), a pair of delivery rollers (6, 7) arranged downstream with respect to the entry rollers (3, 4), and a pair of intermediate rollers (11, 12) arranged between the entry rollers (3, 4) and the delivery rollers (6, 7). The ring spinning device further comprises a first supply (29) to supply a first roving (15) between the pair of entry rollers (3, 4), a second supply (30) to supply a second roving (14) between the intermediate rollers (11, 12) and a third supply (31) to supply an elastic performance filament (16) between the delivery rollers (6, 7). The first roving (15) and the second roving (14) and the elastic performance filament (16) are spun into the stretch yarn (28) in a spinning triangle (29) after exit of the drafting arrangement (2). |
