  • Patent number: 5577371
    Abstract: An apparatus for hooping a package is described, in which the band in its end position, applied to the package and tensioned, defines a hooping plane which extends in the conveying direction. A band guide channel in the form of a plane, rectangular frame intersects the hooping plane at an acute angle in an intersection line at right angles to the conveying direction. The otherwise customary binding head has a stationary device for holding fast and joining the band loop ends and for separating the oncoming band, and a pivotable device separate therefrom for the insertion and pulling-back of the band. The pivotable device has a pivot axis substantially coinciding with the intersection line. On the insertion of the band into the band guide channel said pivotable device is situated in the frame plane and is pivoted into the hooping plane before or during the pulling-back of the band.

  • Patent number: 5373686
    Abstract: An apparatus is described for hooping a package (8) by means of a band (19) in a hooping plane (5) extending in the conveying direction (4). The band guide channel (7) comprises two portions (10, 13) which lie on opposite sides of the hooping plane (5) and each of which is situated at so great a distance from the hooping plane (5) that they do not impede the conveying movement of the package (8). The portions (10, 13) are joined together, on opposite sides of the package (8), by other portions (9, 11 and 12) which pass through the hooping plane (5). In a position turned through 90.degree., in which the hooping plane (5) lies parallel to the conveying plane (1), the arrangement can also work as a horizontal hooping apparatus.
