Abstract
A thermoplastic tape is wrapped around a package and is tightened by the disclosed strapping or banding apparatus. The ends of the plastic tape can be welded together by a combined strapping and sealing apparatus or even with a separate sealing apparatus. The strapping apparatus includes a positioning system which ensures that a slotted wheel intended for tightening the plastic tape, once the operating cycle is complete, always assumes an optimum position for the re-insertion of the plastic tape. The use of the strapping apparatus is thereby substantially facilitated, since the operator normally does not have any hands free to adjust the slotted wheel that would otherwise be necessary for tape insertion.
