DETAILED DESCRIPTION OF THE INVENTION
As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various forms. The figures are not necessarily to scale, some features may be exaggerated to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention.
FIG. 1 illustrates a hair extension device 1 comprising: a first strip of polyurethane 3b; a plurality of hair 2 having opposing ends, 2a and 2b respectively, the first ends 2a are sewn together and attached to the first strip 3b; the second ends 2b are freely movable and a second strip 3a of polyurethane placed over the first ends 2a of the plurality of hair 2 and over the first strip 3b and then heat sealed to form a panel 9; at least two apertures, 4a and 4b respectively, situated on opposing ends of the panel 9; and a string 5 attached and secured to the apertures 4a and 4b on the panel 9.
FIG. 2 depicts how the plurality of hair 2 is cut to a desired length using a cutting device 18 and the first end 2a of the plurality of hair 2 is sewn together using a sewing device 10. FIG. 3 shows how the sewn end 2a of the plurality of hair 2 is placed on a surface 8 of the first strip 3b of polyurethane. A second strip 3a of polyurethane is then place over the first strip 2b and is heat sealed to form a panel 9. FIG. 4 illustrates how at least two apertures, 4a and 4b respectively, are formed on the panel 9 using a hole punching device 30. A string 5 having opposing ends, 5a and 5b respectively, are attached to apertures 4a and 4b. 
It is noted that other materials besides polyurethane may be used to form the panel 9. It is further noted that the hair extension device 1 of the present invention can be manufactured by hand or by machine. The hair can be human, animal or synthetic.
