ABSTRACT:
The machine has a base with a yoke mounted thereon. Into the base is incorporated a band sliding device and on driving the same, a band which can be unwound from a supply reel is advanced for winding around a package located below the yoke. The end of the band is held in a joining station. The band sliding device drive is then reversed, so that the band is increasingly tightly engaged around the package and is tensioned with an adjustable force. This is followed by the joining of the band ends and the separation from the supply reel in the joining station. For setting the band tension, an electromagnetic clutch is used, in which the restoring force of the armature, which aids the release of the clutch, is produced by a magnetic field.
