Abstract

See full text

A spinning preparation machine for producing a roving from a fiber bundle includes a vortex chamber having an infeed opening for the fiber bundle and a yarn forming element extending at least partially into the vortex chamber. The spinning station includes spin nozzles, which lead into the vortex chamber in the region of a wall enclosing the vortex chamber and via which air is introduced into the vortex chamber in a specified direction of rotation in order to set the fiber bundle, which is fed in a transport direction, into rotation in the region of an inlet mouth of the yarn forming element. The yarn forming element includes a draw-off channel, which adjoins the inlet mouth and via which the yarn can be drawn out of the vortex chamber. The wall of the vortex chamber has a transition section, which adjoins the infeed opening, and has the shape of the circumferential surface of a truncated cone, and the diameter of which increases in the transport direction. The spin nozzles lead into the vortex chamber in the region of the transition section and each has a direction of flow that is oriented in the direction of an outer surface of the wall enclosing the vortex chamber.
