Abstract: A method for mounting on a clamp parts or profiles in a processing center provided with a supporting frame for a turntable, comprising a robot for the loading/unloading of the profiles to be worked and of the subsequently worked profiles. The method provides for the steps of inserting the profile to be worked, by means of the robot, in a region arranged below at least one first open clamp; resting the profile to be worked on at least one first lower fixed reference, resting the profile to be worked on a second and/or third front fixed reference, resting the profile to be worked on at least one fourth lateral fixed reference, laterally closing the profile to be worked and then upper closing of the profile to be worked.

Abstract: A suction cup unit for gripping workpieces comprises a suction cup member carried by a support body within which a device is arranged for autonomously generating a vacuum to be applied to the suction cup member. The vacuum generator device includes an ejector-effect device, configured to generate a vacuum by supplying a flow of pressurized air through a nozzle, a reservoir of pressurized air connected to the nozzle, at least one electrically-operated valve for controlling the connection between the pressurized air reservoir and the nozzle, and a connecting line between the nozzle and the suction cup member, for transmitting a vacuum to the suction cup member when pressurized air is made to flow through the nozzle.
