ABSTRACT:
The thread feeding wheel is capable of preventing static-electricity from being produced due to rapid feeding of the thread and which provides a surface having a low frictional coefficient so that the thread feeding around the thread feeding wheel would subject to minimal frictional damage. The cylindrical body is made of an aluminum alloy. A layer of oxide of the aluminum alloy is formed by a hard anodizing process on the middle portion of said cylindrical body. A layer of polytetrafluoroethylene resin is impregnated over said oxide layer to further reduce the frictional coefficient of the thread running surface.
