English Tech/Engineering Mechanics / Mech Engineering fin molding line

"The wire tap-down off timing is very flexible. The wires need to move down only a very short distance before retracting. The stacker doors closing time is more sensitive. If the doors close too early, the fin could be drawn back toward the suction sheet. If the doors close too late, the next fin coming out of the press might not pull up against the suction sheet, caution it to be blocked against the tip of the first stacker rod."

...do you think this could be a suction cup?
