PROCESS FOR PRODUCING GLASS PLATE AND GLASS PLATE PRODUCING EQUIPMENT

摘要

A situation where glass chip produced as a result of breakage of waste glass sheets floats in a cutting chamber when the waste glass sheets produced in glass sheet producing steps are collected is suppressed. Provided is a glass sheet production installation (1), in which a sheetshaped glass ribbon (B) is formed by supplying molten glass (A) into a forming body (2) and causing the molten glass (A) to flow downward on a conveyance path extending in an upper and lower direction from the forming body (2), and the glass ribbon (B) is cut into a predetermined dimension in a cutting chamber (6) provided on the conveyance path so that glass substrates (C) are produced. The glass sheet production installation (1) is provided with a drop hole (8) provided in a floor surface of the cutting chamber (6) and a collection chamber (7) provided under the cutting chamber (6) and is configured so as to collect waste glass substrates of the glass substrates (C) by dropping the waste glass substrates through a drop hole (8) into the collection chamber (7), the glass substrates (C) being obtained by cutting.
