ABSTRACT:
Coilable, tape-like structures are disclosed, that contain parallel segments of dental floss. Each segment has a bead on each of its ends for handling by an applicator. The beads can be fixed to the ends of a floss segment, either by melting its ends (without allowing the melted bead to contact a solid surface) or by press fitting the floss into slits in molded beads and fixing them with a bonding agent. The coilable structures can be made, either by mounting the floss segments onto a flexible tape or by fastening beads of adjacent floss segments together. In the latter version, the floss is (optionally) made stiff enough to support its weight, laterally. Apparatus for producing the coilable structures includes an elongated, substantially-flat, rotating chassis on which floss from a tensioning dispenser is wound. In one embodiment, a tape is held onto the upper surface of the chassis while the floss is wound into slits in the edges of the tape. The floss is then divided into segments by knives on a long blade that slides in the underside of the chassis. Then the free ends of the floss are melted, to produce spheroidal beads thereon, as the tape and central portions of the segments are shielded from the heat source. When the shields are withdrawn, the floss-loaded tape is rolled into a coil. Apparatus for making coilable structures wherein beads on adjacent floss segments are fastened directly together, without a supporting tape, is also disclosed.
