PURPOSE:To upgrade the quality of glass plate by attaching a separation plate or the like to a lower part of flow rate regulating tweel and making the surface layer flow of molten glass changed into a heterogenous layer by volatilization not to feed to a molding part. CONSTITUTION:The manufacturing apparatus of lameller glass is composed of a temp. regulating vessel 2, a flow rate regulating tweel 7 which is formed thereto and provided to an upper part of a flow path for glass material and capable of up-and-down, a separation plate 12 and a guide part 13 provided thereto by which the surface layer flow 14 is led to both sides of flow path. The above- mentioned regulating vessel 2 is provided between a molten furnace storing the molten glass material 4 and a molding part to make the temp. of the material 4 uniform. Also, the above-mentioned separation plate 12 is attached to the upstream side face of lower part of the tweel 7 to separate the surface layer flow 14 of the material.
