Abstract (en)

A threader comprises two guide clips that include two first sections parallel to one another and two second sections converging at an angle and adjacent to the first sections. The second sections transition into curved fourth sections whose peaks have a smaller distance from one another than the first sections. The curved fourth sections are followed by diverging fifth sections. <??>A threader (19) comprises a hook to grasp an upper thread (63); two guide clips, one located on each side of the hook; and a swivel arm that holds the hook and the guide clips and that is fastened to a lower end of a rotating guide stem and through which the hook and the guide clips are held and can be moved into and out of an area of a needle (7). The guide clips comprise two first sections that are parallel to one another and two second sections that converge at an angle and are adjacent to the first sections. The second sections transition into curved fourth sections having peaks that have a smaller distance from one another than the two adjacent first sections. The curved fourth sections are followed by diverging fifth sections.
