    摘要: An integral strip and fastener installation system is provided for light weight slate and tile roofing systems installed with a single overlap between each row or course of tile. A specialized fastener hook is formed with one or more lateral projections or wings installed underneath one or more slate tiles to anchor the fastener to the roof at least in part by the weight of the overlying tiles. This anchoring supports and reinforces the open mouth of the hook against deflection from high winds and thereby enables the hook to hold a tile securely under high wind loads.

    摘要: A double sided polypropylene knit loop fabric comprises at least one and preferably both of the inner and outer loops comprised of polypropylene yarn forming cantilevered loops from a knit fabric. Polypropylene has many different characteristics than those of cotton or cotton blends. Accordingly, by making at least one of the loops, if not both of the loops, and the tie yarn out at least substantially, if not principally, polypropylene, a fabric can be produced which has different characteristics than a cotton fabric of similar construction.
