Ranheim Papirfabrikk
Ranheim Papirfabrikk AS was a Norwegian industrial company, which ran a paper factory with the same name at Ranheim, Trondheim, Norway. The construction of it started in 1882, and it was opened as "Ranheims Cellulosefabrik" in 1884 by businessperson and politician Lauritz Jenssen, a son of Lauritz Dorenfeldt Jenssen who had bought the farm Ranheim and started developing industry there. The factory utilized water from the nearby river Vikelva. The factory also utilized an industrial railroad track, running off of the Nordland Line from Ranheim Station. In 1891 it was changed from a cellulose factory to a paper  factory, and the name changed accordingly. The founder's son Lauritz Jenssen Dorenfeldt, who worked there from 1884 to 1894, was important in this development. In 1894 the Jenssen family did not manage to run the factory any more, and the shares were taken over by Christian Christophersen. The factory survived and was dominating in its field north of Dovrefjell, until the 1960s when it got a sizeable competitor in Nordenfjelske Treforedling. Ranheim Papirfabrikk became a part of Norske Skogindustrier in 1971. In 1983 the company was sold to the conglomerate M. Peterson & Søn, founded in 1801 in Moss. Following  a later reorganization the production unit at Ranheim has been split in two; "Peterson Linerboard AS, Ranheim" and "Peterson Emballasje AS, Ranheim", parts the two main branches "Peterson Linerboard" and "Peterson Packaging" respectively. However the factory still exists.
