Title:
METHOD AND APPARATUS FOR PRODUCING GLASS PLATE
Document Type and Number:
WIPO Patent Application WO/2019/054127
Kind Code:
A1
Abstract:
In executing a step for supplying a liquid (9) over a support table (3) provided with suction holes (3a), a step for disposing a glass plate (2) on the support table (3), a step for fixing the glass plate (2) to the support table (3) by means of suction by using a vacuum tank (10) connected to the suction holes (3a) via a flow path (4), and a step for machining end faces (2a) of the glass plate (2), the flow path (4) is branched several times by multiple branch headers (6, 7). Furthermore, the flow-path sectional area between a first solenoid valve (8), which is provided on the flow path (4), and a vacuum pump (5) is set to be larger than the flow-path sectional area between the first solenoid valve (8) and the suction holes (3a).
