ABSTRACT:
A method and apparatus for producing a laminated pack of mineral fibers comprising two sections, each having a forming conveyor, a plurality of sources of mineral fibers positioned to successively deposit the fibers onto the forming conveyor to form a layer of fibers, vacuum means to provide suction to the fibers through the forming conveyor, the suction being sufficient to force substantially all of the fibers down onto the forming conveyor, thereby crushing the bottom portion of the layer and forming a bottom surface which is smooth relative to the top surface, and means for joining the top surfaces of the layer formed in each section by diverting each layer downwardly while maintaining the suction on the layers to produce a laminated pack having as its outer surfaces the bottom surfaces of each of the two layers.
