Abstract
PURPOSE: To form a spherical body at the tip end of each of comb teeth under the surface tension of a molten resin and thereby preventing the skin of the head from being injured during combing, by a method wherein the tip end parts of teeth of the comb made of thermo-plastic synthetic resin are heated to melt the tip ends.
CONSTITUTION: The tip ends of the teeth of the comb 1 made of thermoplastic synthetic resin are heated to the melting point of the resin to partly melt the comb teeth. Then, when heating is stopped, a surface tension is applied to the molten resin itself so that one drop-shaped spherical body 2 is integrally formed at each of the tip ends of the comb teeth.
EFFECT: No special skill is required, and yet the finished product is excellent in appearance. In addition, the skin of the head can be massaged by the tip ends of the comb teeth.
