This project was implemented during spring 2021 as a bachelor thesis for the Bachelor Engineering Program in Mechanical Engineering at Karlstads University. The project wascarried out in collaboration with Stora Enso Skoghall Mill, which produces different types of cardboard material. In 2020, the overall production capacity was 875 000 tons of cardboard material. In November 2020 Skoghall Mill was authorized to precede an investigation regarding a possible production increase, which would result in a self-sufficient pulp production and an increase of 120 000 tons cardboard material per year.  The cardboard is winded into rolls before they are being transported to the customers. Before the transportation, the reels are given a protecting wrapping. This procedure occurs in a production segment called the Wrapping Line, which is a part of the Finishing Department. The Wrapping Line is one of the production areas that would be affected by a potential increase of production. Therefore, the responsible of the unit wanted to examine if the Wrapping Linehad enough capacity for a potential increase of this size.  The purpose of this paper was to carry out a capacity analysis for the line, identify bottlenecks in the flow and to present arrangements to make the production line more effective. Furthermore, an additional purpose was to identify how long the maintenance stops could beif the potential production increase is approved.  The capacity analysis was carried out using a simulation software called JaamSim. A model of the existing system was built in JaamSim, which afterwards was analyzed. The capacity analysis showed that Emballeringen has the needed capacity if the production increase isapproved. The capacity analysis also displayed the possible length of maintenance stops. Arrangements in flow was presented and prioritized so that the capacity in the Wrapping Linewould increase further.
