Then, the air chamber 408 is activated, causing the slide bar of the second cylinder 406 to move upward. As it moves upward, it pulls the suction cup 407, causing it to deform. At this point, the suction cup 407 picks up the paper. Then, the cylinder 402 depresses, and the first platform 403 resets under the elastic force of the return spring 404.
