A method of making a laminated shingle is provided. The method includes coating a shingle mat with roofing asphalt to make an asphalt-coated sheet, adhering a reinforcement member to a portion of the asphalt-coated sheet, covering the asphalt-coated sheet, and optionally covering the reinforcement member, with granules to make a granule-covered sheet, dividing the granule-covered sheet into an overlay sheet and an underlay sheet, wherein the overlay sheet has a tab portion normally exposed on a roof and a headlap portion normally covered-up on a roof, the headlap portion having a lower zone adjacent the tab portion and an upper zone adjacent the lower zone, and wherein the reinforcement member is adhered to the lower zone of the headlap portion and laminating the overlay sheet and the underlay sheet to make the laminated shingle.

A landscape edging for use on a stone surface, the edging solving the problem that known edging has a poor shaping effect, is higher in cost and cannot satisfactorily harmonize with vegetation. The landscape edging comprises an edging body, the edging body having flexibility, and an outer wall thereof being provided with a decoration layer made of stone granules. When in use, an isolation belt can satisfactorily harmonize with the surrounding environment, and has a certain flexibility, can achieve better shaping, has a better usage effect and is a good substitute for an existing landscape edging.

A roofing shingle includes an asphalt-coated overlay sheet, an underlay sheet having a front surface secured to the overlay sheet, and a reinforcement member is secured directly to the asphalt coating of the headlap portion of the overlay sheet without extending into the tab portion. The asphalt coated overlay sheet includes a first granular material secured to a first portion of a front surface of the headlap portion of the overlay sheet along the nail zone, and a second granular material secured to a second portion of the front surface of the headlap portion of the overlay sheet adjacent to the first portion of the front surface of the headlap portion, with the first granular material providing a thinner cross-section than the second granular material to define a depressed surface extending along said longitudinal axis of the nail zone.

A shingle includes a substrate having an asphalt coating on a top surface of the substrate and on a bottom surface of the substrate. A surface layer of granules is embedded in the asphalt on the top surface of the substrate. A backdust layer of particles is embedded in the asphalt on the bottom surface of the substrate. A sealant is disposed on the backdust. A hydrophobic material is applied to the sealant.

A roof covering material is provided, as well as its method of manufacture, wherein a substrate, preferably of a fibrous material is provided, with a bituminous material, preferably asphalt coating, on opposite surfaces thereof, with granules being applied to an upper surface thereof and at least partially embedded in the bituminous material, and with a discontinuous top layer applied to the granule/bituminous material. The discontinuous top layer is preferably a polymeric material, and openings are provided therein, for passage of fluids therethrough, to avoid moisture, volatiles, and other fluid materials from being trapped beneath the top layer. Various techniques for application of the various materials, and for chemical treatment, are likewise provided.

An asphalt shingle manufacturing machine that includes a curtain die for applying a liquid release layer on an asphalt coated substrate. The moisture of the liquid release layer evaporates leaving a dispersed solid particulate release layer. The curtain die includes a first body section and a second body section with a shim disposed between the body sections to define a distribution channel. The second body section may include chamber manifold defined therein to store a volume of liquid release agent. The distribution channel places the chamber manifold in fluid communication with a discharge outlet of the curtain die in order to disperse a volume of liquid release agent from a chamber manifold out of the discharge outlet. The shim may be configured to define a width of the distribution channel to determine the flow rate and discharge pattern of the liquid release agent.
