| 1. | Elastic balloon made of leather with a air hose fixed in it. |
| 2. | According to claim one, the leather is very strong to bear the great inner and outer pressure. |
| 3. | According to claims one and two, a hose for compressed air. |
The problem and deficiency with prior art: The traditional method depends on heating and hammering the steel in order to remove the painting from the body of the car. During the process reforming steel by hammering the body does not return to its normal shape and become uneven. It is highly costed and takes long time.
The new with the invention: An elastic balloon made of leather modified to match the shape of the car steel body after reforming.
The detailed description: This invention relates to a new method for reforming the car steel body.
Within the relevant method an elastic balloon has circular or square shape is used. A metal tube is fixed at the terminal end of the balloon inside a hose with a length more or less than 15cm. The balloon is fixed from inside between the main chassis and the outer steel body behind the part to be repaired. The balloon is blown by a compressor via the tied hose. The air pressure reaches about 2.5-4. 5 kilos and it increases in accordance with the balloon size. The air pressure presses the damaged part of the car body in a way matches the car chassis.
The method of exploitation: The balloon of this invention could be used for reforming car body easily with low cost.
