Abstract (en)
[origin: WO8601235A1] In preparation for the fibre-joining process an underpressure is brought into effect outside the fibre transport path on the circumference of an opening cylinder (11), the underpressure being greater than the spinning underpressure which is effective at the opening (130) of the feed channel (13) for the fibre collection surface (33). In this way, the fibre flow over the opening (130) is diverted away and sucked up. At the start of the actual fibre joining process this underpressure is suppressed, so that the fibre flow is led to the fibre collector surface (33). To control the fibre flow an underpressure source (5) can be connected to the suction opening (52) by a switch-over device (64) and an underpressure line (51).
