  • Weaving heddles having distancing deformations
    Patent number: 6105623

A first of the deformations is located at one of the end loops at the upper end of the pair, a second of the deformations is located at one of the end loops at the lower end of the pair, and a third of the deformations is spaced a predetermined distance in a direction toward the thread eye of the heddle away from the end loop at the lower end of the pair.
