Abstract: A bagging machine may include a supply handling assembly, a bag loading assembly and a controlled, which may control certain operations of the bagging machine. The bag loading assembly may include a bag opening assembly that reciprocates back and forth and which supports movable film grippers. The bagging machine may be provided with one or more sensors operatively positioned to detect whether a film is present between the grippers, such as during an opening sequence, and the controller may be configured to modify the operation (e.g., interrupt or re-start an opening sequence, generate an alert signal, etc.) of the bagging machine based on the data received from the sensor.
