Abstract

See full text

A method and system for manufacturing a consolidated cellulosic article having first (22) and second surfaces (24) of a desired contour, a uniform density and variable caliper and basis weight are disclosed. The method and system employ a primary press having first (40) and second (41) similarly contoured platens to consolidate a mat (38) of cellulosic material and a binding agent to a softboard having first level of density with first and second opposed sides of similar contour. A removal tool (46) is then employed to remove cellulosic material from one or both of the first and second sides in a planar fashion. The resulting mat is then compressed a second time by a secondary press having first (54) and second (56) platens corresponding in shape to a higher density level while maintaining a substantially uniform caliper and basis weight.
