Abstract
In order to avoid the need for providing expensive fine rovings, a process is proposed in which two rovings are supplied to respective ring spinning stations (3). A common primary roving (2) is drawn and is subsequently divided into two separate rovings (2a, 2b) for feeding respective ring spinning stations (3). The primary roving (2) is divided into two separate rovings (2a and 2b) by conveying means (11), which comprise two juxtaposed suction zones (12a, 12b), which extend in the direction of conveyance.
