Problems solved by technology

However, since glass has a small elongation, when the transfer of the glass web is controlled based on the elongation of the glass, the glass web tends to break
Therefore, the glass web cannot be transferred using existing transfer devices

Embodiment Construction

[0023] Reference will now be made in detail to the exemplary embodiments of the present invention taken in conjunction with the accompanying drawings.

[0024] The present invention relates to a method of manufacturing a sheet. The sheet manufacturing method manufactures a sheet S by cutting an object O supplied in the shape of a web W unwound from a roll.

[0025] For this purpose, the object O supplied in the shape of a web W is conveyed and processed, and the web W is conveyed in a non-contact manner using an ultrasonic vibrator. The effective area of ​​the object O is transferred in a non-contact manner using the ultrasonic non-contact technique disclosed in Korean Patent Application Publication No. 10-2010-0057530. The object O is conveyed in a non-contact manner downstream of the apparatus for producing sheets, wherein a non-contact cutting unit 502 with a laser completely cuts the object O into sheets S which are then conveyed in a non-contact manner to subsequent oper...

Abstract

The present invention provides a sheet manufacturing method comprising: an unwinding step of supplying an object from a roll on which the object is wound; a feeding step of feeding the supplied object; and a cutting step of cutting the fed object, wherein the cutting comprises sheet-cutting in which the object is cut in the width direction of the object. Further, the present invention provides a sheet manufacturing apparatus comprising: an unwinding part for supplying an object from a roll on which the object is wound; a feeding part for feeding the supplied object; and a cutting part for the fed object, wherein the cutting comprises sheet-cutting in which the object is cut in the width direction of the object.

Description

technical field [0001] The present invention relates to methods and apparatus for manufacturing sheets, and more particularly to methods and apparatus for manufacturing sheets by a roll-to-roll process. Background technique [0002] As display devices become thinner and lighter, glass substrates also become thinner. In addition, displays with curved surfaces instead of flat surfaces are now being manufactured, and research into flexible displays is actively underway. Therefore, glass substrates are required to be thinner and more flexible. [0003] When conveying or processing ultra-thin glass sheets (having a thickness of 0.5 mm or less) as in the prior art, the flexibility of the glass makes it difficult to input the glass sheet into the processing line or convey the glass sheet along the processing line or transfer the glass The sheet is conveyed out of the processing line. In addition, the throughput rate is still not optimized because the individual slices have to be...
