Abstract

A method for the application of suction tubes to packing containers is disclosed. Portion-sized packages for juice and the like are often equipped with suction tubes to facilitate the emptying thereof. 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 wrapped tubes are separated from a continuous band while an adhesive is applied to the containers. The containers and tubes ae oriented in relation to each other and then the tubes are attached to the containers.
