Abstract: A method of making granule-covered roofing material comprises discharging granules onto continuously moving asphaltic material, pressing the granules into the asphaltic material, directing light toward the granule-covered asphaltic material, measuring the reflected light from the granule-covered asphaltic material, and responding to the measured reflected light by modifying a process parameter to effect a change in the reflectance of light from the granule-covered asphaltic material.

Abstract: A reoriented insulation assembly and the method of making same is disclosed. The insulation assembly includes a plurality of mineral fiber sections, such as fibrous glass sections. Each of the sections has a machine direction, a cross direction and a loft direction. The sections are positioned in an abutting relationship with the cross direction or the machine direction of the sections defining the thickness of the insulation assembly. An exterior cover encloses the plurality of abutting sections. The reorientation of the sections places the forces generated by the fibers in a desired relationship for installation in a building.

Abstract: Apparatus particularly adapted for applying foamed treating liquor to a flat width of a traveling non-woven textile substrate includes a longitudinal tubular foam distribution nozzle one side of which has a plurality of closely-spaced staggered apertures for engaging and applying pressurized foam widthwise across the substrate and a driven drum opposed to the nozzle engaging widthwise the opposite side of the substrate for imparting traveling movement to the substrate. The drum and nozzle cooperate to compress the substrate therebetween in covering relation over the apertures to prevent lateral escape of the foam therefrom and to confine the emission of foam therethrough, thereby to uniformly control foam application across the substrate width as it travels by the nozzle. Limited contact of the apparatus with the substrate prevents frictional pulling and structural damage thereto. The drum is perforated for escape of the air component of the foam and to enhance foam penetration of the substrate.
