Abstract: A laminate composite sheet comprising a two-ply base layer comprised of a bottom ply and a top ply, wherein the bottom ply is comprised of unbleached cellulosic fibers and wherein the top ply is comprised of bleached or brightened cellulosic fibers and a further layer attached to the top ply with a layer of adhesive; said further layer having a top and a bottom surface, said further layer selected from the group consisting of paper or film; said layer of adhesive containing no pigment, and said top surface of said further layer having no coating.

Abstract: A method and apparatus for controlling the operating speed of a manufacturing facility is disclosed. It includes determining a desired operating speed that is dependent on at least one economic variable. The variables vary with the operating speed. Also, the operating speed is adjusted (if necessary) in response to the determination. Preferably the control is closed loop and includes determining a current operating speed and comparing the current operating speed to the desired operating speed. The operating speed is controlled in response to the comparison. The economic variable is preferably a cost of manufacturing, and/or manufacturing inflows, and/or manufacturing outflows. The economic efficiency is dependent on one or more economic variables that vary with operating speed. The current economic efficiency of the facility is obtained along with information on the business transactions that affects the economic variables.

Abstract: A laminated paperboard package is produced by initially printing graphics by high speed printing on a sheet of clay-coated publication paper. The printed paper is then continuously applied to a surface of cellulosic substrate and bonded to the substrate, preferably through use of starch as an adhesive, to provide a laminated product. The laminated product is then die cut to the desired shape, folded and glued into the configuration of a box or container. A layer of water absorbent, cellulosic fiber material can be bonded to the inner surface of the substrate to prevent moisture from the contained product from seeping outwardly through the substrate to the printed paper.

Abstract: A method and apparatus for controlling the operating speed of a papermaking facility is disclosed. It includes determining a desired operating speed that is dependent on at least one economic variable. The variables vary with the operating speed. Also, the operating speed is adjusted (if necessary) in response to the determination. Preferably the control is closed loop and includes determining a current operating speed and comparing the current operating speed to the desired operating speed. The operating speed is controlled in response to the comparison. The economic variable is preferably a cost of manufacturing, and/or manufacturing inflows, and/or manufacturing outflows. Also, a method and apparatus that determines the effect of one or more business transactions on the economic efficiency of the production of products in a paper manufacturing facility is disclosed. The economic efficiency is dependant on one or more economic variables that vary with operating speed.
