Abstract: A shingle including a fibrous substrate that reduces or prevents asphalt bleed through is provided. The fibrous substrate has a top surface and a bottom surface opposed to the top surface. Asphalt coating is applied to the top surface of the fibrous substrate. The fibrous substrate includes fibers having a diameter of 3.5 microns to 30 microns and a length of 3.175 mm (? inch) to 50.8 mm (2 inches). In addition, the fibrous substrate has (i) a basis weight of 39.05 g/m2 (0.8 lb/100 ft2) to 134.3 g/m2 (2.75 lb/100 ft2) and/or (ii) a thickness of 0.381 mm (15 mils) to 1.143 mm (45 mils). A ratio of the amount of asphalt coating on the bottom surface to the amount of asphalt coating on the top surface is from 0:1 to 1:5.

Abstract: A shingle includes a substrate, a surface layer of granules, a backdust layer, an adhesive, and a hydrophobic material. Asphalt is applied to the substrate to form a first asphalt coating on the top or upper surface of the substrate and a second asphalt coating on the bottom or lower surface of the substrate. A surface layer of granules is embedded in the first asphalt coating. A backdust layer of particles is embedded in the second asphalt coating. A adhesive is disposed on the backdust layer. The hydrophobic material is applied to the adhesive.

Abstract: An apparatus configured to form masonry siding products is provided. The apparatus includes a mold having a mold bottom and a plurality of mold walls defining a mold cavity. A mold carrier is configured to support the mold bottom and the mold walls. The mold carrier has a first member that extends upwardly from a base member and a second member that extends upwardly from the base member. The first member forms an internal first angle of about 90° with the base member. The second member forms an internal second angle in a range of from about 100° to about 110° with the base member. The internal first angle formed by the first member and the base member and the internal second angle formed by the second member and the base member are configured to allow for easy removal of the mold from the mold carrier.

Abstract: A demolding apparatus for removing molded building products from a mold has a conveyor assembly to advance the mold in a machine direction.
