Abstract: A roller is mounted on a pivot pin connecting two operating handles. In operation, two further rolls or rollers mounted on two further pivot pins, each connecting a respective jaw lever to one of the operating handles, bear on this roller. The jaw levers pivot about fulcrum pins and are provided with closing jaws for closing a clamping seal used to join the ends of a packing ligature or band. The rollers relieve the pivots of load, so that the tongs containing the jaw levers are suited to the transmission of elevated forces.
