Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0027] figure 1 is a schematic side view showing a first exemplary embodiment of the apparatus for manufacturing rolls according to the present invention.

[0028] figure 1 The apparatus for manufacturing rolls shown in includes a forming unit 400, a transport unit 100, a redirection unit 600 and a winding unit.

[0029] The forming unit 400 forms the raw material into a glass web (glass web, or “glass soft plate”) W. The redirection unit 600 changes the direction in which the glass web W is transported. exist figure 1 On the paper of , the redirection unit 600 changes the transport direction from a vertical downward direction to a horizontal direction. Specifically, the glass web W formed in the forming operation is conveyed vertically downwards to a redirection unit 600 disposed on the path along which the glass web W is conveyed. The tran...

Abstract

The present invention provides a roll manufacturing method characterized by comprising: a shaping step of shaping a base material into a web; a transferring step of transferring the shaped web; and a winding step of winding the transferred web into a roll. In addition, the present invention provides a roll manufacturing device characterized by comprising: a shaping unit for shaping a base material into a web; a transferring unit for transferring the shaped web; and a winding unit for winding the transferred web into a roll.

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...
