Abstract
Abstract A supply roll of longitudinally oriented synthetic sheet is provided having alternating relatively thick longitudinal ribs and relatively thin longitudinal webs. The sheet is advanced, and selected webs are torn to separate the sheet into a plurality of tapes of a desired width. The tapes are then fed directly in line into a loom or knitting machine and woven or knitted into a fabric.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
99 words
A method of making fabrics comprising: providing a supply roll of a longitudinally oriented synthetic sheet having longitudinal striations embossed therein forming alternating relatively thick longitudinal ribs and relatively thin longitudinal webs; advancing said sheet from said supply roll; initially separating a portion of said sheet into a plurality of tapes of a desired width; advancing adjacent tapes in diverging directions vertically away from each other while maintaining tension in the longitudinal direction uniformly across said sheet to tear the webs between said adjacent tapes; and continuously feeding said tapes into a fabrication machine to form a fabric therefrom.
Claim 2
Independent Claim
99 words
A method of making fabrics comprising: providing a supply roll of a longitudinally oriented synthetic sheet having longitudinal striations embossed therein forming alternating relatively thick longitudinal ribs and relatively thin longitudinal webs; advancing said sheet from said supply roll; initially separating a portion of said sheet into a plurality of tapes of a desired width; advancing adjacent tapes in diverging directions vertically away from each other while maintaining tension in the longitudinal direction uniformly across said sheet to tear the webs between said adjacent tapes; and continuously feeding said tapes into a fabrication machine to form a fabric therefrom.
Claim 3
Independent Claim
108 words
A method of making fabrics comprising: providing a supply roll of a longitudinally oriented open network structure having a plurality of pArallel spaced continuous longitudinal filaments interconnected in the spaces between adjacent filaments by fibrils; advancing said sheet from said supply roll; initially separating a portion of said network structure into a plurality of tapes of a desired width; advancing adjacent tapes in diverging directions vertically away from each other while maintaining tension in the longitudinal direction uniformly across said network structure to tear the fibrils between said adjacent open network tapes; and continuously feeding said open network tapes into a fabrication machine to form a fabric therefrom.
