    • The present invention relates to a process for manufacturing flat sheets of a glass-based material and to an apparatus therefor. The process comprises providing a glass preform, heating the glass preform in a furnace, forming a gob and a pre-sheet, removing the gob and drawing the glass pre-sheet into a flat glass sheet. Also provided is an apparatus for drawing a glass preform into a glass sheet, the apparatus comprising a draw furnace, stretching arms for stretching and drawing the pre-sheet into a glass sheet, and opposing edge rollers for applying a downward force on the glass sheet. The draw furnace may include a plurality of individual heating elements, the temperature of each heating element capable of being separately controlled. The apparatus may further include an annealing furnace for annealing the glass sheet.
    • 本发明涉及一种用于制造玻璃基材料的平板的方法及其装置。 该方法包括提供玻璃预制件,在炉中加热玻璃预成型件,形成料滴和预薄片,除去料滴并将玻璃预片材拉成平板玻璃板。 还提供了一种用于将玻璃预成型件拉制成玻璃板的设备,该设备包括拉丝炉,用于拉伸和拉伸预成型片的玻璃板的拉伸臂,以及用于向玻璃板施加向下的力的相对的边缘辊 。 拉丝炉可以包括多个单独的加热元件,每个加热元件的温度能够被单独控制。 该装置还可以包括用于退火玻璃板的退火炉。
