ABSTRACT:
Disclosed is a high speed binding device wherein a package wound with a binding thread is fixed to a flange of a flyer with its thread-winding axis in parallel with the rotation axis of said flyer and the binding thread is drawn out in the direction of the winding axis; and thereafter said binding thread is passed through a first tensioner for imparting to the binding thread a back tension decreased with a rise in the rotation speed of the flyer and then through a second tensioner for imparting to the binding thread a back tension increased with a rise in said rotation speed, thereby to cause said decrease in the back tension to be offset by said increase in the back tension, thus to bind, with a substantially constant back tension, the binding thread about the outer periphery of an element assembly passing through a through hole coaxially bored through the flyer.
