Claim:
1. A spinning position on an air-jet spinning machine, which serves to produce a yarn from a fiber strand consisting of fibers, comprising: a turbulence chamber with an inlet port for the fiber strand entering the turbulence chamber in a direction of conveyance during operation of the air-jet spinning machine; a yarn-forming element extending into the turbulence chamber, the yarn-forming element having an intake mouth and a draw-off channel through which yarn is drawn off out of the turbulence chamber; air jets directed into the turbulence chamber, the air jets opening into the turbulence chamber in a wall surrounding the turbulence chamber, such that air can be introduced through these jets into the turbulence chamber in a predefined direction to impart to the fiber strand a twist in the area of an intake mouth of the yarn-forming element; a guide arrangement situated in the area of the inlet port of the turbulence chamber, the guide arrangement further comprising at least two guide sections spaced a distance apart from one another that decreases in at least some sections in the direction of conveyance of the fiber strand; the guide arrangement further comprising at least one central guide element that extends at least partially between the guide sections viewed in a section running perpendicular to a longitudinal axis of the draw-off channel and producing a deflection of the fibers of the fiber strand perpendicular to the longitudinal axis of the draw-off channel; and wherein the guide sections are formed by one of mandrels or guide plates that extend from a wall surrounding the inlet port of the turbulence chamber towards the inlet mouth of the yarn-forming element.
