The invention relates to a strapping head or to a strapping apparatus of a strapping device for strapping packed goods by means of a strap, in particular by means of a plastic strap, which strapping head or strapping apparatus is provided with an advancing apparatus and tensioning apparatus having a plurality of wheels for transferring an advancing, retracting, and tensioning motion to the strap, wherein at least one of said wheels is or can be operatively connected to a driving apparatus in order to cause the at least one of the wheels to rotate about an axis of rotation for the advancing, retracting, and tensioning motion. The problem addressed by the invention is that of improving said strapping head or strapping apparatus to the effect that the strapping head can be made as compact as possible. This problem is solved in that, in total, at most three rollers are provided on the strapping head for contact with the strap during the performance of the advancing, retracting, and tensioning motion, which rollers come in contact with the strap in connection with these functions, wherein the at most three rollers can be brought in contact with the strap in pairs on both sides of the strap in different combinations with each other. |
