(57) ABSTRACT OF THE DISCLOSURE This publication describes an apparatus for wrapping different sizes of paper rolls (1) or rolls of like material into a wrapper by rotating the rolls (1). The apparatus comprises a support frame (2) encompassing the roll (1), means for conveying the wrapper on the roll (1), and at least one flexible guide band (3) which is devised to press on the outer surface of the roll (1) and to comply with the rotating of the roll. In the apparatus according to the invention, the guide band (3) is configured into an endless conveyor with an at least approximately U-shaped form, within which the roll (1) to be wrapped is inserted. The inner loop (4-5-6-7) of the conveyor is configured to pass over four such guide rollers (4...7), mounted on the two first lever are (8, 9) and the two second lever arms (10, 11), are capable of being transferred against the outer surface of the roll (1) to be wrapped. Then, the guide band (3), which passes over the guide rollers (4...7), during the wrapping phase touches the surface of the roll (1) to be wrapped at each point within the three circumferential segments (4-5, 5-6, and 6-7) between the guide rollers (4...7) on the outer surface of the roll (1) to be wrapped.
