Abstract
Abstract The elongated tape comprises a flexible continuous outer laminae of a first plastic material heat-fused at first segments directly to opposed exterior portions of the fastener shanks spaced along said tape and laminated second segments alternately arranged with and interconnecting the first segments. Each second segment has an outer laminae formed of corresponding portions of the continuous outer laminae with a flexible inner lamina of a second plastic material. The melting point of the inner laminae of the second segment is lower than that of the outer laminae.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
136 words
A flexible fastener strip adapted to be fed when in a taut condition through a fastener-driving tool, said strip comprising a plurality of fasteners each having an elongated shank; and flexible plastic tape means circumferentially engaging and interconnecting said fastener shanks and maintaining said fasteners in a predetermined spaced relationship, said tape means having flexible continuous outer laminae of a first plastic material heat-fused at first segments directly to opposed exTerior portions of said fastener shanks spaced along said tape means, and laminated second segments alternately arranged with and interconnecting said first segments, each second segment having outer laminae formed of corresponding portions of said continuous outer laminae with a flexible inner lamina of a second plastic material, the plastic materials of the inner and outer laminae of said second segments having a disparate melting points.
Claim 2
Dependent Claim
136 words
A flexible fastener strip adapted to be fed when in a taut condition through a fastener-driving tool, said strip comprising a plurality of fasteners each having an elongated shank; and flexible plastic tape means circumferentially engaging and interconnecting said fastener shanks and maintaining said fasteners in a predetermined spaced relationship, said tape means having flexible continuous outer laminae of a first plastic material heat-fused at first segments directly to opposed exTerior portions of said fastener shanks spaced along said tape means, and laminated second segments alternately arranged with and interconnecting said first segments, each second segment having outer laminae formed of corresponding portions of said continuous outer laminae with a flexible inner lamina of a second plastic material, the plastic materials of the inner and outer laminae of said second segments having a disparate melting points.
Claim 3
Dependent Claim
20 words
