Abstract From the Canadian patent

A machine for the application of suction tubes to packing containers. Portion-sized packages for juice and the like are often equipped with suction tubes to facilitate the emptying. The suction tubes which for reasons of hygiene are individually wrapped in paper, are very light and therefore difficult to handle and to attach to the outside surface of the packing container by mechanical means. The invented machine separates the wrapped tubes from a continuous band, applies an adhesive, orientates each packing container and tube in relation to each other and attaches the tube to the container.
