The method as claimed in any one of the previous claims, wherein the pathway (10) is formed by a pathway-forming device (20) pressing the at least portion of the wrapping material (3) against the interior disc (2).

The method as claimed in any one of the previous claims, wherein the method comprises directing a pathway-forming device (20) into contact with the at least portion of the wrapping material (3) in order to form the said pathway (10), and wherein the method comprises directing the said pathway-forming device (20) away from the area between the exterior disc (4) and the interior disc (2), thereby allowing the head press unit (30) to press exterior disc (4) against the interior disc (2).

The method as claimed in any one of the previous claims, wherein the exterior disc (4) and/or the interior disc (2) comprises an adhesive for attaching the exterior disc (4) to the interior disc (2).

The method as claimed in claim 7, wherein the head press unit (30) comprises a heating device for heating the adhesive in order to attach the exterior disc (4) to the interior disc (2).

The method as claimed in any one of the previous claims, wherein the head press unit (30) comprises a vacuum device configured to hold the exterior disc (4) against the head press unit (30).

The method as claimed in any one of the previous claims, wherein the wrapping material (3) is a wrapping paper.

• a conveyor line (50) for transporting a paper roll (1), wherein an interior disc (2) is arranged to the end (1A) of the paper roll (1), a wrapping material (3) is wrapped around the outer roll surface (1B) of the paper roll (1), and wherein the wrapping material (3) is arranged to extend beyond the edge of the interior disc (2) such that it partially covers the end surface (2A) of the interior disc (2),
• a head press unit (30) positioned adjacent to the conveyor line (50) for attaching the exterior disc (4) to the interior disc (2), and
• a pathway-forming device (20) positioned adjacent to the conveyor line (50) for forming the pathway (10) to the wrapping material (3).

The arrangement as claimed in any one of the claims from 11 to 14, wherein the pathway-forming device (20) is coupled to the head press unit (30), and/or to the conveyor line (50).
