Glass ribbon producing apparatus and process for producing the same

摘要

A glass ribbon producing apparatus (1) which feeds molten glass (Y) to a forming member (2) and causes the molten glass (Y) to flow downward from the forming member (2) to form a sheet-like glass ribbon (G) includes reheating portion (5) provided on a transport route for the glass ribbon (G) caused to flow downward from the forming member (2), and is configured so that the glass ribbon (G) is reheated by the reheating portion (5) to cause the sheet thickness of the glass ribbon (G) below the reheating portion (5) to be smaller than that of the glass ribbon (G) thereabove.
