BOBBIN FOR COILLING AMORPHOUS MATERIAL

摘要

The present invention relates to a bobbin for winding an amorphous material that includes a cylindrical device body which is provided so that the amorphous material is wound; and a material adsorbing unit which is disposed in the device body to take air into a space between the amorphous material and the device body so that the amorphous material is adsorbed along a circumference of the device body, in which the material adsorbing unit has a cylindrical adsorption plate that is arranged along an outside circumference of the device body; a plurality of through-holes that are arranged in a circumferential direction of the adsorption plate so that air between the amorphous material and the adsorption plate is taken in; and an air flow path that is arranged to be connected between the through-hole and an air intake unit taking in air in the device body. According to the present invention, the amorphous material is adsorbed to a surface of a winding roll to be stably wound along a circumference of the winding roll. Also, winding levels of a cooling roll and the winding roll are matched with each other so that winding quality can be improved.
