Patent ID: 6928803

Claim:
A device for producing a spun thread from a strand of staple fibers, comprising: a spindle having a yarn guiding channel defined therethrough and an inlet opening to said yarn guiding channel; a fluid device disposed relative to said inlet so as to generate a fluid turbulence around said inlet opening; a fiber guiding element disposed so as to deliver the strand of staple fibers to said inlet opening, said fiber guiding element comprising a fiber conveying channel with a bottom fiber guiding surface along which the staple fibers of the fiber strand are conveyed in a generally flat adjacent arrangement to a presenting edge of said fiber conveying channel at an end of said fiber guiding surface; and wherein said fiber guiding surface extends along a first plane to a diverting point, and from said diverting point to said presenting edge, said fiber guiding surface extends at a downward angle towards said inlet opening such that free ends of the staple fibers conveyed in the flat arrangement along said fiber guiding surface are caused to protrude as a result of the deviation in said fiber guiding surface.
