Abstract
Two false-twist belts are each entrained about crowned pulleys. The belts are arranged so that their outer-facing surfaces cross one another with one belt pressed against the other. Yarn is passed between these false-twist belts and twisted. The bending rigidity in the lateral direction of the false-twist belts is set to a value in which the outer-facing surfaces of the false-twist belts are rounded into a convex curvature at the position where the belts are pressed against each other.
