For speeds of up to 80 bags/min, the bags can be accelerated directly into the waiting case. For higher speeds, the bags are pre-collated and are transferred into the case or tray by a pusher mechanism.
The pre-erected case or tray takes up a near vertical position with the open side facing the incoming bags. As each bag or pre-collated stack enters the case, the case indexes downwards until it is filled. A new case indexes into position, while the filled case exits from the Model KV 250 on the machine discharge belt.
