- Pushing the product from the index conveyor in the desired quantity and creating groups via the comb driver mechanism
- The comb driver mechanism is equipped with an anti-collision system based on FESTO pneumatics
Cartoning system:
- Retrieving flat carton cuts from the warehouse using an electric arm with vacuum suction cups
- Moving a group of products into a preformed carton using a servo motor driven bulk feed arm
- Collective feed arm equipped with a mechanism for squeezing a group of products using a FESTO pneumatic drive
