PURPOSE:To feed a worked material in stable ways by arranging an endless chain belt which is formed by axially connecting transport base boards for generating a magnetic force on the outer peripheral surface, inside a feeding belt, and contact-arranging the horizontal traveling upper part onto the inner surface of the horizontal traveling upper part of the material feeding belt. CONSTITUTION:A material feeding belt 6 is made of the material which easily permits the permeation of magnetic force, and grinding grains are attached to increase the frictional force on the surface. An endless chain belt 11 is formed by connecting the transport base plates having a permanent magnet attached, by a shaft. Therefore, the worked material W is attracted onto the material feeding belt 6 and travelled. An endless sanding belt 22 is press-attached in the grinding parts B1 and B2, and grinding and polishing works are applied onto the upper surface of the worked material W. At this time, the transport base plates are separated against the magnetic force from the inner surface of the material feeding belt 6 at the terminal edge of the horizontal traveling upper part (y). With such constitution, the worked material W can be transported in stable ways, and fine grinding and polishing can be executed. |
