Nature doesn’t like empty spaces and does its best to fill them. This is what makes vacuum-based handling systems so strong. When the air is emptied from a suction cup, nature does its best to fill the empty space by pulling the suction cup even more tightly against the opposing surface. This is the simple principle exploited by COVAL SAS in its suction-based handling systems. The French company sees itself as a vacuum manager, producing vacuum pumps and suction cups but selling solutions to customers worldwide.
