Abstract: This patent publication discloses a method and assembly for placing an identification label to the end of a paper roll (1). Prior-art methods for placing the label have been hampered by the long duration of the work cycle caused by the picking movement of the label. According to the present invention the label is picked by means of a clamp element (7) from a slanted surface inclined at an angle of, e.g., 45.degree. from horizontal and transferred to the end of the roll (1) via an activation phase of the adhering surface by way of a continuous horizontal transfer movement, thus achieving a short work cycle. The assembly designed to implement the method performs the transfer movements by means of an arm (6) travelling along a guide rail (5) and a clamp element (7) connected by a joint (8) to the end of the arm (6).
