- Another document G 93 09 868.5 discloses a bag teaser for opening and emptying of garbage bags or similar products that must pass through a narrow passage on a conveyor belt, wherein the geometric dimensions of the passage is smaller than that of the garbage bags and thus the bags are made to burst so that the subsequent brush wheels continue to pick up the bags and rip them completely open.
- the known in the prior art devices for opening garbage bags all have the disadvantage that they do not reach the desired and necessary opening degree of garbage bags and beyond a high wear caused by the mechanical opening.
- a further disadvantage is the fact that the operational reliability can not be guaranteed, because the garbage bags to be opened do not all have the same geometric dimensions, so that it is difficult to use the appropriate mechanical means for all different bag sizes, so that all sacks are opened can be.

Eine weitere Druckschrift G 93 09 868.5 offenbart einen Sackaufreisser zum Öffnen und Entleeren von Müllsäcken oder vergleichbaren Produkten, die auf einem Förderband eine enge Passage durchlaufen müssen, wobei die geometrischen Ausmaße der Passage kleiner als die der Müllsäcke ist und somit die Säcke zum Platzen gebracht werden, so dass die anschließenden Bürstenräder die Säcke weiterhin aufnehmen und vollständig aufreißen sollen.Another document G 93 09 868.5 discloses a bag teaser for opening and emptying of garbage bags or similar products that must pass through a narrow passage on a conveyor belt, wherein the geometric dimensions of the passage is smaller than that of the garbage bags and thus the bags are made to burst so that the subsequent brush wheels continue to pick up the bags and rip them completely open.

Ein weiterer Nachteil ist darin zu sehen, dass die Betriebssicherheit erkennbar nicht gewährleistet sein kann, denn die zu öffnenden Müllsäcke haben nicht alle die gleichen geometrischen Ausmaße, so dass es schwierig ist, für alle unterschiedlichen Sackgrößen die geeigneten mechanischen Mittel einzusetzen, damit alle Säcke geöffnet werden können.Furthermore, the known in the prior art devices for opening garbage bags all have the disadvantage that they do not reach the desired and necessary opening degree of garbage bags and beyond a high wear caused by the mechanical opening. A further disadvantage is the fact that the operational reliability can not be guaranteed, because the garbage bags to be opened do not all have the same geometric dimensions, so that it is difficult to use the appropriate mechanical means for all different bag sizes, so that all sacks are opened can be.
