The special shape of the bellow suction cups allows an immediate gripping after contact with the surface of the object by existing vacuum, because the bellows contracts very quickly. The object will be raised a few centimeters regardless of the movement from the automatic. This rapid movement prevents, that the underlying load will be moved (stay on his position).

Due to this specification, bellow suction cups are recommended wherever paper and cardboard sheets, thin metals, glass panels etc. should be moved separately. Their high flexibility allows gripping as well by uneven or inclined surfaces. The fixtures are made with anodized aluminum with a central threaded bolt including an internal and external thread for suction and attachment to the machine. The holders were only put into the suction cups.
