The Array Pack AP-25 is a fully automated carton stacking and banding system that offers revolutionary versatility, performance and reliable operation. The AP-25 stacker collects product from an up-stream operation such as a carton filler machine in its first stage position until a predetermined count is achieved. From there, products are either indexed into the banding position or shifted over for the next column/row of product to be stacked. Once the entire bundle is accumulated, it's indexed into the banding position by a high-speed stepper motor.
