The device for elimination of trimmings RF of rolls or logs L of sheetlike material, cut into smaller rolls R of limited length, comprises means of grasping and transfer of the rolls and means of unloading the trimmings RF. A conveyor 413 picks up the cut rolls R from a feed zone, spaces them out one from another and transfers them to a grasping means 415, which grabs the rolls R on top from the conveyor and transports them onto a conveying means 440. The grasping means 415 comprises a flexible element 429, permeable to air and associated with aspiration means 421 for the grasping of the rolls R, said aspiration means comprising a perforated wall 427, with said flexible element 429 travelling on one surface thereof, there being produced through said perforated wall and said flexible element an aspiration to grab and hold the rolls R. <IMAGE> |
