<p>In order to join the threads on an open-end friction spinning device with two friction spinning elements (101) driven in the same direction and forming a suction-type tapered gap, the thread (30) is fed to the gap in such a way that the thread (30) first reaches the thread-forming region (104) with its free end. The feeding of the fibres into the tapered gap is controlled in such a way that the end of the thread (300) comes in contact with the fibres simultaneously with arrival in the thread-forming region (104). The friction spinning elements (101) are covered with a shroud (130) which forms a fibre-feeding duct (24). The shroud has, in addition to the fibre-feeding duct (24), a thread insertion slit (14) which extends essentially in the longitudinal direction of the friction spinning element (101). This extends from the outer side of the shroud (130) to its inner side and from the end of the withdrawal side up to a maximum distance of the end of the opening (240) which faces away from the withdrawal side. Outside the tapered gap a thread-holding device (7) is installed, which maintains the thread (3) essentially parallel to the thread input slit (14). This keeps the thread (30), at the withdrawal end of the friction element (101), away from the tapered opening until the end of the thread (30) has reached the tapered gap.</p> |
