Abstract (en)
[origin: WO2015044728A1] The invention relates to a fiber guiding element for a spinneret (2) of an air-jet spinning machine which is used to produce a thread (3) from a fiber sliver (4). The fiber guiding element (1) has a main part (5) with an outer surface (6) which is used for bearing against a counter surface (7) of a spinneret (2) of the spinning station in order to allow the fiber guiding element (1) to be fixed in the region of an inlet opening (8) of the spinneret (2). The fiber guiding element (1) has an inner surface (9) which can be brought into contact with the fiber sliver (4) during the operation of the spinneret (2) and which is used to guide the fiber sliver. According to the invention, the inner surface (9) comprises multiple bulges (10), preferably bulges which are oriented radially inward, in a fiber guiding element (1) cross-section running perpendicularly to a central axis (11) of the fiber guiding element (1). At least some of the bulges (10) have a contour which tapers inwards at least in a front region (33) facing the central axis (11). The invention further relates to a spinning station of an air-jet spinning machine, comprising a corresponding fiber guiding element.
