An open-end spinning device having a thread draw-off nozzle and a thread draw-off nozzle for an open-end spinning device, the thread draw-off nozzle having a thread-guiding surface which extends between an entry opening and a draw-off opening and which tapers in the shape of a funnel toward the draw-off opening. In order to provide a thread draw-off nozzle and an open-end spinning device having a thread draw-off nozzle which allows controlled production of the thread, the thread draw-off nozzle has a blocking element, which protrudes from the thread-guiding surface and which has a thread stop surface designed such that the thread stop surface blocks a thread from circulating over the thread-guiding surface.

Fibre band opening device for an open-end spinning device having a feed tray, a fibre band pull-in cylinder, and an opening roller having an opening roller clothing, the tips of which lie on a circular cylindrical surface, a support surface for fixing a fibre tuft, which is processed by the opening roller by combining, the distance of which support surface from the circular cylindrical surface is tapered in the fibre transport direction to a minimum distance, and a transition area having a convex curvature between the clamping surface and the support surface. The support surface has a distance of between 4 and 8 millimetres from the circular cylindrical surface at the beginning of the support surface with respect to the fibre transport direction, and the minimum distance of the support surface from the circular cylindrical surface is less than 1.5 millimetres.

An open-end spinning device having a rotor housing () which can be acted upon by negative pressure and a spinning rotor (), the rotor housing () is open towards the front and can be closed by a cover element, to the rear the rotor housing () has a rear wall () with a passage opening () for a rotor shaft () of the spinning rotor (). In order to prevent the occurrence of thread coils inside the rotor housing () behind the spinning rotor, a narrow gap () of less than 2 mm is provided between the spinning rotor () and the rear wall () of the rotor housing () at the largest outer diameter of the spinning rotor () and the rear wall () of the rotor housing () is designed such that the area () behind the spinning rotor () is covered inside the rotor housing ().
