Abstract (en)

A suction cup gripping head for the opening of a paper or cardboard tray identifying a quadrilateral perimeter of adjustable size comprises four gripper elements (43) placed in pairs at the ends of two opposite sides of the perimeter, associable with pairs of opposite glued flaps, outer and inner, (111A, 111'A) of the tray (111), in which each gripper element (43) is equipped with a first set of inner suction cups (44) that are engageable from the inside against the inner glued flap (111'A) of the tray, and a tear device that is engageable from the outside against the outer glued flap (111A) of the tray, in which the tear device is applied to an arm (46) tilting about a fulcrum (47) adapted to detach the outer glued flap (111A) of the tray with its own rotary movement. The relative method for opening a paper or cardboard tray is also part of the invention.
