ABSTRACT:
The present invention relates to sterile dental floss segments having integral tips on the ends thereof, that are compatible for use in dental floss rings and similar type dental floss holders. The dental floss segments have a predetermined length, and are enclosed in a laminated web matrix containing multiple strands of dental floss, which maintains the integrity of the sterility of the dental floss, even after one or more of the strands are removed for use, and also allows for the sterilization of the dental floss strands after laminating the web. The present invention further relates to the method and apparatus to manufacture the sterile web units containing the sterilized dental floss segments with the integral tips on the ends. The method includes unwinding strands of floss in a parallel fashion, such that the strands resemble a web coming off a loom, passing the web through a thread guide to align and adjust the tension in the floss, applying beads of hot melt adhesive material to the exposed sections of the floss to create tips on the ends of the floss, laminating the floss with two layers of sterilizable glassine substrate material, perforating and die-cutting sections of the laminated web across the web at the back hardened beads.
