Self-locking vacuum cups with traction release These cups do not require a connection to any vacuum source, since the object onto which they are laid on evacuates the air inside them. A built-in non-return valve prevents the air from entering again, thus maintaining the vacuum. To release the piece, simply lift it a few millimetres, thus opening the non-return valve, which restores the atmospheric pressure inside the cup, by letting the air in. Since possible losses cannot be recovered, these cups a recommended only for holding objects with smooth and impermeable surfaces, such as glass, polished sheets, and other similar objects. They are particularly suited for glass carrying trolleys feeding trolleys for robotic systems. They are made with nickel-plated brass with a steel drive bush, which can be provided in the anti-rotation version upon request.
