ABSTRACT Suction tube packages consisting of suction tubes wrapped in protective envelopes, which with the help of adhesive tapes are joined to a coherent "rope-ladderlike" band, are used to facilitate the mechanical handling and the application of the wrapped suction tubes to packing containers. The suction tube bands are difficult to manu- facture with high accuracy, since the suction tubes sur- rounded by the protective envelopes, owing to their un- defined, varying contours, are difficult to orientate in correct position on the adhesive tapes. In accordance with the invention it is proposed to manufacture the protective envelopes as well as the tapes joining them at the same time and of the same material. The suction tubes are placed with equal intervals transversely between two thermoplastic webs, whereupon these are sealed to each other around the suction tubes. At the same time the webs are punched or cut so that individual suction tube enve- lopes are obtained which are mutually connected by means of straps extending between the envelopes. In this manner all handling of separate wrapped suction tubes is avoided, so that the suction tube band can be manufactured with appre- ciably greater precision. The invention relates to the method of manufacture as well as to a machine for its realization and the finished suction tube band.
