Abstract

A method for removing slack from dental floss in a molded plastic dental flosser which comprises a handle and arms formed of a first plastic and a strand of dental floss extending with slack between and engaged to the arms, with opposite ends of the strand of dental floss extending outward of the arms, the strand of dental floss having a nominal breadth and formed of a lubricous second plastic which is different from and not chemically bonded to the first plastic, the method for removing slack comprising the steps: a. immobilizing the arms from moving, b. pulling the opposite ends of the strand of dental floss in opposite directions while the arms remain immobilized, such that portions of the strand of dental floss are moved axially through the arms until the slack in the dental floss extending between the arms is removed, c. heating, melting and severing the dental floss at locations immediately outward of each of the arms, thereby forming at least one coalesced bead in each of the severed ends of the dental floss, where each of the beads has nominal diameter transverse of the axis of the strand that is greater than the nominal breadth of the strand, and d. releasing the arms of the flossers from the immobilization of step a.
