Abstract: A method for tying balloons and the like, having apertured ends and necks, comprising the steps of: looping the neck of the balloon around a pair of movable jaws resiliently urged toward one another and defining a channel therebetween perpendicular to their plane of movement; moving the end of the balloon over the loop and through the jaws, so as to extend through the channel; and, rolling the loop over the end of the balloon, continuing toward and off the ends of the jaws, whereby the loop resiliently snaps into place, forming a knot in the neck of the balloon. The method may further comprise the step of feeding a string through one of the pair of movable jaws so as to extend through the loop prior to rolling the loop over the end of the jaws, whereby a plurality of balloons can be sequentially and automatically tied on the string.
