Abstract
The band movement drive of a machine for the automatic hooping of a package with a hooping band has a main band drive and a secondary band drive. During band advance, the hooping band is guided by the main band drive at a first, higher speed in a band channel for enveloping the package up to its entry in a joining station, followed by a switching over to band retraction, which takes place at the same higher speed. The secondary band drive is driven at a higher speed than the main band drive, so that a band reserve is formed beween the two band drives. When the hooping band is loosely applied to the package, switching over takes place to a second, lower speed, at which the band reserve is retracted. The hooping band is then tensioned with the tension set on the main band drive and then in the joining station the band and band end are joined together and the band is separated from the band supply. During the time created during the retraction of the band reserve, it is possible to switch over clutch in the band movement drive for changing to the second, lower speed without damaging the hooping band or package through overtensioning.
