Abstract
Abstract A fastener device for fastening papers or the like to a backing member including a strip or prong member having a central portion and bendable prong end portions on which papers are to be impaled and an overlay member for fixing the strip member to the backing member. The overlay member has an intermediate portion adapted to overlie the central portion of the strip member and also has end portions having a pair of apertures through which the prong end portions extend. The overlay member has adhesive on its lower surface to bond it to the central portion of the strip member to thereby retain it in position so that it will not become misaligned in handling prior to the time that the overlay member is adhesively secured to the backing member. The fastener devices are fabricated on a web and coiled into a roll from which single fastener devices are adapted to be severed incidental to the process of securing each fastener device to a backing member.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
154 words
A continuous web of fastener devices comprising an elongated web, a plurality of fastener devices on said web, each fastener device comprising an overlay member having first and second edges on opposite sides thereof and also having an upper surface and an undersurface and a central overlay portion located between spaced overlay end portions, spaced apertures in said overlay end portions, an elongated prong member extending through said spaced apertures and having a central portion located in contiguous relationship to said undersurface at said central overlay portion, said elongated prong member also having spaced prong end portions at opposite ends of said central prong portion located in contiguous relationship to said upper surface at said overlay end portions, means on said undersurface for bonding said central prong portion to said overlay member, and a first edge of a first overlay member being secured relative to a second edge of an adjacent second overlay member.
Claim 2
Dependent Claim
154 words
A continuous web of fastener devices comprising an elongated web, a plurality of fastener devices on said web, each fastener device comprising an overlay member having first and second edges on opposite sides thereof and also having an upper surface and an undersurface and a central overlay portion located between spaced overlay end portions, spaced apertures in said overlay end portions, an elongated prong member extending through said spaced apertures and having a central portion located in contiguous relationship to said undersurface at said central overlay portion, said elongated prong member also having spaced prong end portions at opposite ends of said central prong portion located in contiguous relationship to said upper surface at said overlay end portions, means on said undersurface for bonding said central prong portion to said overlay member, and a first edge of a first overlay member being secured relative to a second edge of an adjacent second overlay member.
