Abstract: A method and apparatus for processing compressible insulation material of mineral fibers in which a folding shoe guides the insulation material from a strip condition into a cylindrical condition and further including initially compressing the portion of the strip material along the centerline thereof, subsequently compressing the portions of the strip material intermediate the center line and the side edges of the strip material, and, finally, compressing the side edge portions of the strip material.

Abstract: A porous article with a special finish treatment is provided, the article typically being an article of furniture, such as a cabinet door, by way of illustration. The article can be made of a molding compound comprising discrete glass fibers which can be produced by milling cured phenolic-bonded glass fibers. A coupling agent or binder is added to the milled fibers and the combination formed and cured under heat and pressure into the shape of the article. The surface of the formed article is porous and, in fact, the article is porous throughout its thickness. This presents a substantial problem in applying a satisfactory finish. To overcome this, with the article at an elevated temperature, it is immersed in a liquid containing particles in suspension, i.e. polyester liquid containing talc.

Abstract: A method of moldng a product which involves delivering a supported body or mass of material that may be molded such as mineral fibers impregnated with a binder into a contoured molding facility, the body or mass of material being compressed and shaped to the mold contour, the binder set or cured and the molded product removed from the mold concomitantly with the advance of a succeeding supported mass or body of moldable mineral into the molding facility.
