METHOD FOR MANUFACTURING TRANSPARENT MEMBERS, SUCH AS GLASS AND THE LIKE, AND ARTICLES OBTAINED WITH THE METHOD ITSELF
Document Type and Number:
WIPO Patent Application WO/2000/061383
Kind Code:
A2
Abstract:
Method for manufacturing transparent members (10) consisting in forming a chamber (11) between two plates (14, 16), by interposing gaskets and/or rigid profiles (12, 18) and sealing the chamber (11) to maintain the liquid therein. It is possible that one of the plates (14, 16), defining the chamber (11), is provided with valve means to allow admission, removal and replacement of the liquid, or the same valve means is located on the perimeter of the chamber (11).
