Provided herein is a method for producing glass-ceramic sheets. The method includes texturing at least one surface of a first glass sheet, and stacking the first glass sheet and a second glass sheet. The first glass sheet and the second glass sheet are stacked so that the textured surface of the first glass sheet contacts a surface of the second glass sheet. The first and second glass sheets are cerammed. After cooling, the cerammed first and second glass sheets are separated. Also provided is a pre-form for producing glass-ceramic sheets. The pre-form includes a first glass sheet having a textured surface, and a second glass sheet contacting the first glass sheet. The textured surface of the first glass sheet is in contact with a surface of the second glass sheet.

Provided is a glass film-resin composite which makes it possible to obtain a long-length (e.g., 500 m or more-long) glass roll. The glass film-resin composite comprises a glass film, and a resin tape laminated to at least one surface of the glass film through an adhesive, wherein the width l (mm) of the resin tape satisfies the following formula (1). $\begin{array}{cc}la\frac{E_g\sqrt{t_g}}{E_p{t}_p}& \left(1\right)\end{array}$
(where: a represents a reinforcement coefficient (mm*(m).sup.1/2) which is 1.10 or more; Eg represents the Young's modulus (GPa) of the glass film; Ep represents the Young's modulus (GPa) of the resin tape; tg represents the thickness (m) of the glass film; and tp represents the thickness (m) of the resin tape.).

Devices for preparing ultra-thin flexible glass and methods are provided. A feeding system, a preheating heating annealing furnace body, an edge clamping system, a drawing system, a laminating system, a winding system, and a cutting system are provided to satisfy overall production of flexible glass. The clamping device clamps two ends of the glass. The glass is drawn at a discharging end and fed at the feeding end, thereby forming a continuous drawing with feeding and drawing. The overall horizontal setting of device avoids high-level operation. The preheating heating annealing furnace body includes a preheating section, a heating section, and an annealing section. The temperature change of the glass is more compact through the gradient temperature control of the heating device. Temperature-measuring points in the preheating heating annealing furnace body are designed in a grid-like manner, which clarifies temperature points of glass blocks, and facilitates temperature adjustment, so that the glass is uniformly heated, and fracture of the glass caused by uneven heating, uneven drawing thickness, or uneven heating and cooling are avoided, thereby ensuring the glass drawing utilization rate and enhancing the utilization rate of the glass plate of uneven thickness.
