Abstract: The apparatus (4) manually operable with a tightening lever (16) has a cutting station (8), a tightening station (10) and a clamping station (12). The latter has a clamping arm (18) mounted on an eccentric shaft (20) and having a clamping shoe (40) through which the strip end (3) inserted in the strip channel (5) is clamped. The clamping shoe (40) is laterallly displaced with respect to the axis of the eccentric shaft (20) in the direction of the strip end (3) in the vicinity of a clamping nose (35) supported on the supporting face (36) of the apparatus casing (15). On lowering the clamping shoe (18) into the clamping positioning an additional clamping force on the clamping shoe (40) is exerted by the clamping nose (35) guided on the supporting surface (36).

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.

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.
