A continuous manufacturing line for preparing gypsum fiberboard is provided. The manufacturing line includes equipment for admixing hydratable gypsum, paper, and a quantity of water to form a substantially homogenous slurry, dewatering apparatus for removing a portion of the excess water from the slurry to produce a substantially continuous wet web, pressing equipment for configuring the wet web with a compression means to form a substantially continuous green board, a cutting station for cutting the substantially continuous green board into individual uncured lengths, and a heating station for curing the individual uncured lengths to form gypsum-dihydrate-containing fiberboards.

An apparatus for use in alternatively and selectively forming wallboard or fiberboard comprising: means for providing a fiberboard-forming slurry; means for producing a substantially continuous wet web from said fiberboard-forming slurry; means for forming a substantially continuous green board from said wet web; means for dispensing a wallboard-forming gypsum slurry onto a continuously moving wallboard substrate to form a slurry-laden substrate; means for introducing at least one continuously moving wallboard substrate beneath said dispensing means; first carrier means located past said dispensing means for carrying said slurry-laden substrate or said green board away from said dispensing means; second carrier means for receiving said green board and carrying said green board past said dispensing means and to said first carrier means; and means for selectively introducing and withdrawing said second carrier means from operative association with said first carrier means.
