The present invention relates a method and system for placing headers (24) to the ends of paper or paperboard rolls (1) by way of inserting the headers into the tubular cavity formed by the overlapping rim of the roll wrapper to the roll end. According to the method, the roll (1) to be packaged is transferred to the header inserter station, a header (24) of desired type for the roll is fetched from a header support shelf (3) and delivered to a header inserter grabber (17 - 23) of a header inserter assembly (5) waiting in its delivery position. Next, the header (24) is transferred by a movement of the header inserter grabber (17 - 23) into the tube formed by the wrapper overlap, and subsequently, the header (24) is transferred against the end of the roll (1). According to the invention, the header (24) is transferred into the wrapper tube by means of rotating the header inserter grabber (17 - 23) about a shaft (16), which is offset from the transfer path of the roll and is aligned orthogonal to the longitudinal axis of the roll, whereby the header (24) is made to advance into the wrapper tube in a tilted position so that the edge of the header (24) situated closer to the shaft (16) enters the wrapper tube before the entry of the trailing edge of the header into the same.
