ABSTRACT:
TECHNICAL FIELD
The present invention relates to hair styling tools and more particularly to a braid heat sealing device for cutting and heat sealing the cut end of synthetic braided hair extensions; the braid heat sealing device including a scissor assembly and a heating element assembly; the scissor assembly including two pivotally connected opposed scissor members each having a thermally insulated plastic handle portion connected to a metal scissor blade portion having a V-shaped notched formed therein that is alignable with the V-shaped notch of the other scissor member when the scissor assembly is in a closed position; the two scissor members being operable in a scissor cutting mode by squeezing the blade portions together; the heating element assembly including an electric resistance heater element bonded to one of the metal scissor blade portions and supplied with electrical power through wires molded into the plastic handle portion; the wires being connected to an electrical power source sufficient to cause electrical resistance heater element to become heated sufficiently to fuse a section of synthetic hair positioned within the two V-shaped notches.
BACKGROUND ART
Braided synthetic hair extensions are popular hair enhancement products. Although the extension provide desirable enhancements, they must often be trimmed to fit properly which, if not performed properly, can result in braids that become unraveled and unattractive. It would be a benefit, therefore, to have a device that could be used to trim synthetic braided hair extensions and seal the cut ends.
GENERAL SUMMARY DISCUSSION OF INVENTION
It is thus an object of the invention to provide a braid heat sealing device that includes a scissor assembly and a heating element assembly; the scissor assembly including two pivotally connected opposed scissor members each having a thermally insulated plastic handle portion connected to a metal scissor blade portion having a V-shaped notched formed therein that is alignable with the V-shaped notch of the other scissor member when the scissor assembly is in a closed position; the two scissor members being operable in a scissor cutting mode by squeezing the blade portions together; the heating element assembly including an electric resistance heater element bonded to one of the metal scissor blade portions and supplied with electrical power through wires molded into the plastic handle portion; the wires being connected to an electrical power source sufficient to cause electrical resistance heater element to become heated sufficiently to fuse a section of synthetic hair positioned within the two V-shaped notches.
Accordingly, a braid heat sealing device is provided. The braid heat sealing device includes a scissor assembly and a heating element assembly; the scissor assembly including two pivotally connected opposed scissor members each having a thermally insulated plastic handle portion connected to a metal scissor blade portion having a V-shaped notched formed therein that is alignable with the V-shaped notch of the other scissor member when the scissor assembly is in a closed position; the two scissor members being operable in a scissor cutting mode by squeezing the blade portions together; the heating element assembly including an electric resistance heater element bonded to one of the metal scissor blade portions and supplied with electrical power through wires molded into the plastic handle portion; the wires being connected to an electrical power source sufficient to cause electrical resistance heater element to become heated sufficiently to fuse a section of synthetic hair positioned within the two V-shaped notches.
