  • Clamping device for a yarn layer and use thereof
    Patent number: 5373614
    Abstract: A clamping device for clamping a yarn layer includes a clamping rail, a clamping comb that is insertable into the yarn layer, and a reed comb that is also insertable into the yarn layer. The clamping comb is provided with spaced apart clamping lamellae which each have a clamping edge facing the clamping rail for clamping yarn between the clamping rail and the clamping edge of the clamping lamellae. At least one of the clamping rail and the clamping comb are adjustable relative to the other so that the clamping rail and the clamping comb approach one another to clamp the yarn. The reed comb and the clamping comb are longitudinally adjustable relative to one another by an amount greater than the spacing between the adjacent lamellae of the clamping comb in order to deflect the yarn.
