Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
A method to produce a sealed edge product comprising the steps of: providing a supply of textile material, putting a preselected length of material under tension in a pre-determined fixed position, placing a thermoplastic strip of material across the width of said textile material, applying heat and pressure to said thermoplastic strip of material to seal said thermoplastic strip to said textile material, moving a cutting means into registry with said thermoplastic seal while holding said textile material in said pre-determined fixed position, actuating said cutting means to sever said textile material through said thermoplastic seal, moving the severed textile material to a point of collection while putting another length of textile material in said pre-determined position under tension and successively repeating the steps to provide successive textile material segments with the edges sealed across the width thereof.
