Abstract: An automatic machine that holds, inflates, then securely knots ordinary latex party balloons without using accessories includes a filling nozzle, surrounding clamps, and a balloon neck stretcher. Two closable jaws can be raised, lowered, advanced, retracted and twisted about the stretched neck so that a knot is formed in the stretched neck prior to release of the balloon. Mechatronics techniques make the required motions. An optional supply mechanism pre-mounts balloons on rows of nozzles on parallel sliding strips, so that a particular strip can be selected and moved to cause inflation and knotting.

Abstract: Clips of this invention are capable of being held by other, like clips and are capable of holding items such as balloons. Hence decorative objects such as latex party balloons can be strung together in various forms by means of their clips. Preferred clips are moulded in a plastics material. Extenders (lacking the means to hold objects) are also included in the invention. Complex assemblies of party balloons can be assembled on these clips and interlinked. Hundreds of balloons can be reversibly assembled in festoons. Distended balloons are attached by their necks, twisted a few times around holding structures on the clips. The open mouths of the necks are intentionally left trapped in tension against the holding structures so that they cannot unravel. No other seals are needed.
