Description

technical field

[0001] The present invention relates to a method and apparatus for making rolls, and more particularly, to a method and apparatus for making rolls which are capable of preventing contact between the web and the surface of the equipment by means of ultrasonic vibrations, thereby preventing possibility of defects. Background technique

[0002] As display devices become thinner and lighter, glass substrates are also becoming thinner. Due to the continuing trend towards thinner device profiles, the thickness of the substrate has changed from the existing 0.7mm thickness to the currently preferred thickness of 0.5mm or less. At substrate thicknesses of 0.3mm or less, the difficulty of transmission becomes higher compared to existing board types. This therefore reduces yield and limits productivity. Therefore, a method of applying a roll-to-roll process (a process commonly used in the thin film industry) for the manufacture of substrates has been proposed in ord...
