A good Vertical form fill seal machine does not rely on only the pulling belts to pull the film but instead it utilizes several mechanical solutions to ensure the film slag is provided to the pulling belts for easy pull down the forming tube. APPE understands the importance of relieving stress on the friction pulling belts hence we have designed the perfect solution for ensuring an accurate and stress free release of film from the packaging roll stock. APPE has designed a special mandrel on which the core of the packaging film roll stock is installed like a sleeve. The core is normally 3” in diameter. Once the core of the packaging film sits on the mandrel pneumatic pressure is applied from within the mandrel and grippers and inflated to lock the core of the packaging film on the mandrel. This mandrel of the Vertical form fill seal machine is controlled by an A/C motor which is controlled by PLC of the Vertical form fill seal machine. Just before the belts are ready to pull the film the PLC signals the A/C motor to turn the mandrel and release an appropriate quantity of the packaging film from the packaging roll stock.
