ABSTRACT:
BACKGROUND OF THE INVENTION
When synthetic hair is braided, the ends of the braid have a tendency to fray, just like the end of a rope. To keep the ends of synthetic braids from fraying, hair braiders use some type of a heating device, typically a cigarette lighter, matches or a candle, to seal the ends. The “Braid Cutter-Sealer” shown provides a greater degree of safety than an open flame as it is used in a beauty salon, and it also works faster by cutting and sealing the braid in one operation.
THE PRIOR ART
PLIER-type wire-cutters with opposing side-cutting edges appear superficially similar to this invention implement.
However they use sharp edges as cutting means which is Fundamentally distinctive from what is required by this invention which uses flattened edges which are heated to cut and seal braids by melting them.
SUMMARY OF THE INVENTION
The “Braid Cutter-Sealer” is a device designed to cut and at the same time heat seal the ends of synthetic hair braids by melting and fusing together the multiple hair strands that compose the braid. The device consists of 2 blades with small, flat edges facing each other, which touch each other when closed, therefore cutting the braids It is important that these edges NOT be sharp, as they would have a tendency to wear, and the two blades would have a tendency to overlap each other. There is an inclined surface adjacent to the small edges. These inclined surfaces help to seal the entire end of the braid by heating the synthetic braid strands not sealed by the small flat edges during the cutting action. The inclined surfaces face towards the root of the hair when the device is used. The point of the blade is curved towards the tip, which reduces the possibility of the blade burning the scalp when utilizing it to cut and seal short braids. The two blades are maintained in perfect alignment by the 2 curved guides on the side of one blade. The blades are connected to a scissor-like mechanism that allows them to open and close. This mechanism has insulated rotating handles which prevent the operator from burning his/her hands when using. The unit can be heated in suitable stove, or heated by a small electrical heating element, which can be easily attached to one or both blades of the Braid Cutter-Sealer.
