This category contains sites related to the supply and service of paper and board making machinery and a range of specialized products for use by the pulp and paper industry. It also indexes companies involved in equipment for producting single and double sided corrugated rolls and sheets. Note: Sites that are concerned with equipment for converting paper and board products should more properly be directed for indexing in the Business/Industries/Machinery_and_Tools/Converting_Equipment category. Additional note: In effect, a fine line is drawn between equipment used, on the one hand, in the production of corrugated board and, on the other hand, in producing corrugated containers and display products. Where a supplier deals in both kinds of equipment, its site can be (and, because of the its relationship to boardmaking, should be) indexed in the Pulp and Paper category. However, firms that supply only the means for converting corrugated board belong in the Converting_Equipment category instead.
