ABSTRACT:
This gripper is applicable more particularly to textile machines and includes a gripping clamp and an apparatus for opening and closing the clamp. The clamp proper includes a fixed central member provided laterally and on either side with a resilient portion, two arms crossing each other for constituting a pair of gripping jaws, each arm being provided with a key preferably in the outer extension of the resilient portion. The opening and closing apparatus includes a pair of vertically movable fingers, by reason of one per arm, which are adapted in their lower position to depress the keys in order to cause the distortion of the resilient portions and thus modify the degree of crossing of the jaw forming portions.
