ABSTRACT:
In a wire twisting machine in which the ends of the tie wire are clamped while these ends are being twisted together to complete the tying of the product, there is proposed improved clamps which, unlike prior art clamps that have clamping strokes of a prescribed dimension, are actuated by pressure air in such manner that the clamping strokes thereof are terminated only when the clamping rods actually abut against their cooperating anvil or wire holding surfaces. Thus, wear or looseness of fit which may subsequently occur in the components of the machine do not adversely affect the clamping service or function of the clamping rods.
