The suction tubes are placed with equal intervals transversely between two thermoplastic webs, whereupon these webs are sealed to each other around the suction tubes. At the same time the webs are punched or cut so that individual suction tube envelopes 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 appreciably 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.Field of SearchCutting and/or shaping meansConcentric with or at infeed of closure Blank cut-off only Enclosing contents within progressively formed web means Forming a pocket or depression in cover material by applying heat or pressure (e.g., stretch forming) Multirow With closing of web between package units Longitudinal tube formed from single web Concurrent severing Plural webs Vertically disposed tube Simultaneously longitudinal and transverse seaming Forming a pocket, depression, or hollow compartment by application of heat or pressure (e.g., stretch forming) | |
