Abstract
A thread guide formed as a guide eyelet especially for a leno disk has an entrance with an opening angle (.alpha.) and an exit with an opening angle (.beta.). The entrance and exit are interconnected by a guide bore or hole (6) surrounded by a curved bore ring surface or bead (9). The entrance and exit each have a recess (4, 5) surrounded by a respective rim portion (7, 8) of a rim surrounding the thread guide eyelet (2A, 2B). Each rim portion (7, 8) has an edge with a curved ring surface (R1 and/or R3) surrounding the respective entrance (10) and exit (11). The entrance and exit curved ring surfaces are spaced from the bore ring surface or bead (9) so that a thread passing through the thread guide has a small surface area contact with these curved ring surfaces to reduce friction while providing a positive guidance for the thread.
