Apparatus for molding articles of uneven thickness

摘要: A method of and apparatus for preforming moldable compositions fibrous materials a binder in which the preform had portions along its width having different thicknesses corresponding to final molded product. Initially composition is formed into mat has thickness at least equal thickest portion preform, then excess material removed from across by scalping rolls develop contoured thicknesses. Each section weighed separately insure proper density that mat. Following weighing step, again shaped placed mold subsequent heating pressing operation.
