Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
142 words
A reinforced laminated flat tape suitable for weaving into fabric, comprising two outer layers each formed of a sheet material having a non-tacky outer surface and of prescribed positive friction, and an intermediate layer comprising an elongate thread of continuous filaments formed of high tensile synthetic material which extends longitudinally of the length of the tape and are spread to even thickness across the central part and most of the width of the tape but terminate laterally inward of each lateral edge of the tape, and a bonding material applied between the outer layers and across the full width of the tape securing the spread filaments together and to each sheet layer over the entire tape width and effecting a sheet to sheet only connection laterally outwardly of each lateral edge of the filaments and up to each edge of the tape.
