  • two-sided cutting edges provided an enlarged section in the longitudinal direction of the bag opening device is ensured.
  • Alternating chamfers of the adjacent cutting edges may under certain circumstances improve the cutting process for severing the sack material.
  • the cutting bevels are provided on one side of the teeth in the longitudinal direction seen on the teeth. Any arrangement of the chamfers is quite conceivable.
  • the bag-opening device has an overall height or jaw height adapted to the thickness of the bag to be opened in such a way that the prongs opening the bag do not open the bag to be opened at the rear side to match the thickness of the bag to be opened punctured. Consequently, the configuration of the sack opening device or the sheet design of the serrated bridge is adapted to the respectively openable bag such that to reduce a risk of injury of User's teeth do not break the bag to be opened on the back.
  • the fastening device has two opposite fastening sections, wherein a fastening section is provided at each free end of the toothed bridge.
