Abstract
A device to introduce the upper thread into the eye of the needle (7) of a sewing machine which includes two guide clips (49, 51) having two inlet sections (53, 55) ending in a narrow point. The two guide clips (49, 51) are generally identical and can spread evenly when encountering the needle. The grasping hook (57) that lies in a plane in the center of the two guide clips (49, 51) is always guided exactly centered into the eye (25) of the needle (7). In addition, the two guide clips (49, 51) are mounted for tilting movement about a horizontal axis (B).
