Spinning Station of a Spinning Preparation Machine

Abstract

The invention relates to a spinning station of a spinning preparation machine for producing a roving (2) from a fiber bundle (3), wherein the spinning station (1) comprises a vortex chamber (4) having an infeed opening (5) for the fiber bundle (3) and a yarn forming element (6) extending at least partially into the vortex chamber (4), wherein the spinning station (1) comprises spin nozzles (7), which are directed into the vortex chamber (4) and which lead into the vortex chamber (4) in the region of a wall (8) enclosing the vortex chamber (4) and via which air can be introduced into the vortex chamber (4) in a specified direction of rotation in order to set the fiber bundle (3), which is fed in a transport direction (T), into rotation in the specified direction of rotation in the region of an inlet mouth (9) of the yarn forming element (6), and wherein the yarn forming element (6) comprises a draw-off channel (10), which adjoins the inlet mouth (9) and via which the yarn can be drawn out of the vortex chamber (4). According to the invention, the wall (8) of the vortex chamber (4) has a transition section (11), which adjoins the infeed opening (5), has the shape of the circumferential surface of a truncated cone, and the diameter of which increases in the aforementioned transport direction (T), wherein the spin nozzles (7) lead into the vortex chamber (4) in the region of the transition section (11) and each have a direction of flow that is oriented in the direction of an outer surface (12) of the wall (8) enclosing the vortex chamber (4).
