An elevator device in a machine for forming packs of rolls includes an auxiliary plate member, situated between wrapping sheet folders and a constraining plate of a conveying line. The auxiliary plate member moves vertically between a lower end position near and above the folders, and an upper end position in alignment with the constraining plate. When an elevation plate is raised to push a group of rolls partially wrapped with a wrapping sheet against the constraining plate, the auxiliary plate member keeps the rolls and the sheet firm and is moved synchronously with the plate thus carrying the group of rolls and the sheet upwards until they are received within holding means of a conveying line.
