APPARATUS FOR IMPLEMENTING SEALING PIPE Field of the Art

Present invention relates to apparatus used for installing sealing pipes of U-channel type door and boot onto flanges on car frame. The invention is particularly related to a new mounting apparatus produced in order to balance likely variations in flange thicknesses of sealing pipes produced to install onto car body. Background of the Art

Sealing pipes are located onto door and window body constituting frame of the car. Flanges are formed on door and frame of the cars. The flanges are formed on the joint points forming frame or door. While the thickness of flanges is required to be Standard, due to various reasons, differences may occur in flange thicknesses. The flange thicknesses cause some problems in installation of sealing pipes. The sealing pipes should be easy to mount onto flanges. Some problems are encountered particularly in connection with location of sealing pipes onto flanges. It is difficult to overcome the problems arising from faulty installation. Sealing pipes are mounted onto flanges after formation of car frame in production line. Some difficulties are encountered during installation of sealing pipes. In general, air driven installation apparatus are used. Various mounting apparatus have been developed in mounting apparatus used in production to meet the probable variations in flange thicknesses. Although the developed mounting apparatus can meet the probable thickness changes, they do not provide easy to install. It is needed to develop a new sealing pipe implementation apparatus ensuring installation free of problems during production. The fixed roller system proposed in patent application no. GB235662 does not provide such flexibility. In the international patent application no. WD0018601 , the inventor tried to propose a pivot system. Pivot system loses contact surface with axial cycling of the roller. The solution developed in patent application no. US6311378 is not practical and restricts the movement of the mounting component. In general, a guide reel is located under the roller in order to protect car frame. Owing to fixed axial guide reel, no difficulties are encountered in implementation to flanges in different profiles. The position is adjustable due to fixed condition. When it is required to replace it at certain times, no high maintenance costs are incurred. The

_

cost of guide reel is high and it should be changed. The mounting apparatus should also be changed. And it increases the maintenance cost.
