Abstract:
1. A fastening system for use in securing gypsum sheathing board to an underlying framing member, wherein the gypsum board includes a protective face coating and an underlying polymeric compound, the fastening system comprising: a feedband comprising a series of interconnected membranes, each membrane defined by a central extent and a peripheral crimped edge, each membrane formed from a polymeric compound consisting essentially of a thermal setting acrylic polymer, a butyl rubber and a softening agent, a chemical bond being formed between the membrane and the underlying polymeric compound of an adjacent gypsum board when the membrane is heated; a series of fasteners, each fastener having a head and a threaded body, the body of each fastener being secured through the central extent of an associated membrane such that the head and membrane are in contact, an outer membrane area defined by the space between the head and the peripheral crimped edge, the outer membrane area being forced upwardly around the head of the fastener when the fastener is driven into the gypsum board; a powered drill including a delivery mechanism, a chuck and a trigger, the trigger being used to selectively rotate the chuck, the delivery mechanism retaining and selectively advancing the feedband such that the individual heads of the series of fasteners are sequentially delivered to the chuck to thereby enable the individual fasteners to be drilled into the gypsum board; whereby drilling an individual fastener causes the crimped edge of the associated membrane to tear away from the feedband and whereby supplying further rotational force causes the membrane to become heated to thereby facilitate the chemical bond between the membrane and the underlying polymeric compound.
