We Claim:

1. A novel method for manufacturing wheels out of single metal band comprising the step of,

placing a circular metal band 101 in a mandrel 102 provided at a machining tool for manufacturing the wheel;

forming the metal band / work piece 101 for making a desired length of rim 201 and a wheel disc 202;

spinning a nave portion 401 of the work piece 101 for shaping the wheel disc 202; wherein the nave spinning of the work piece 101 utilized to fix an inner width of the wheel;

spinning the work piece 101 for making a gutter 504 and a disc flange portion 502 of the wheel;

rolling one end of the rim portion of the work piece 101 that is connected to the wheel disc 202 portion, to form the required gutter portion 504 of predetermined shape and thickness;

spinning the rim portion of the work piece 101 further to form a tire seat and a well area 701; wherein the well area 701 has a reduced width compared to the rim portion;

forming a flange flare 801 by bending another end of the rim portion outwardly; wherein the flange portion of the wheel rim is formed by bending the flange flare 801 to a desired shape; and

reaming of bolt holes 503 and chamfering bores at the wheel disk portion of the wheel for attaching the wheel to wheel axle.

2. The method of claim 1, wherein during forming process for making the rim and a wheel disc 202 at a predetermined size according to requirement; and wherein the metal band 101 is bent to a predetermined angle 203 to form the desired wheel disc 202 portion 202 with a predetermined thickness.

The method of claim 1, wherein the method for manufacturing wheels out of single metal band 101 further comprising the step of,

forming bolt holes 503 and a central bore 501, before performing the spinning process for forming the gutter 504 and disc flange portion 502 of the wheel. The method of claim 1, wherein the method for manufacturing wheels out of single metal band 101 further comprising the step of,

machining edge 1201 of the flange to avoid sharp edges; and

machining nave 1202 and bore for obtaining final desired shape of the wheel. The method of claim 1, wherein the method for manufacturing wheels out of single metal band 101 further comprising the step of,

piercing air hole 1001 for the wheel disc 202, after forming the flange portion 901 at another end of the rim portion; and coining the air hole, after piercing air hole 1001 for the wheel disc 202.

The method of claim 1, wherein the method for manufacturing wheels out of single metal band 101 further comprising the step of,

reducing the length of the rim portion by a shrinking process, after piercing and coining the air hole 1001.
