Abstract
The invention relates to a device for the production of a spun thread from a staple fiber strand by means of air spin method. The fiber guiding element according to the invention includes a fiber conveying channel with a fiber guiding surface, whereby the fiber guiding surface ends at a fiber presenting edge and leads the fibers of the staple strand in the form of an essentially flat arrangement lying next to each other. The fiber-guiding surface is configured in such a manner that it includes a diverting point which causes a deviation of the staple fiber strand, where the deviation is being provided in such a manner that the free fiber ends of the fibers within the staple fiber protrude from the staple fiber strand.
