A spool of banding material orbits a product to be banded, with the banding material unwinding from the orbiting spool and about the product to form a band about the product As the spool unwinds banding material, the shaft or other structure supporting the spool continuously urges the spool in the rewinding direction, thereby enhancing the tension on the unwinding banding material When initiating a band, gripping fingers grasp an end of the unspooled banding material and hold it adjacent the object being banded as the spool orbits the object and wraps the object and the fingers The fingers then slip out from between the object and the forming band, preferably with the assistance of a blast of pressurized air, and grasp the unspooling banding material between the spool and the banded object The length of banding material extending to the object is cut.
