Abstract
A method and apparatus for handling parcels wherein, for the handling of bulky parcels with a low mass and covered with a relatively fragile wrapping, a gripping method is utilized which serves to exert suction on a relatively large surface area of the parcel so as not to damage the wrapping of the parcels wherein the intensity of suction is controlled and the surface area to which the suction is exerted is determined such that a threshold of tearing resistance of the wrapping is not reached.
