  • This enables flexible storage, especially with regard to the height of the yarn, without having to use specific fixing pins with a fixed, predetermined arrangement of the grooves.
  • the filing of the yarn at different heights on the fixing pins enables a further dimension in the formation of the transverse force reinforcement with the height perpendicular to the plane.
