Oblong suction cup for gripping e.g. curved object, has peripheral wall with bellows and delimited by outer peripheral lip applied on surface of object, where wall provides polylobe contour to cavity
The cup has a chamber connected to a vacuum source and with a cavity (2) that is open in a direction of an object that is to be gripped. The cavity is delimited by a side (3) forming the bottom and having a tubular axial nozzle molded as a single piece with the rest of the cup and connected to a lifting and suction device. The nozzle is engaged on a tube connected to a depression source. A peripheral wall (4) having bellows is delimited by an outer peripheral lip (5) applied on a surface of the object. The peripheral wall provides a polylobe contour to the cavity.
