摘要

PROBLEM TO BE SOLVED: To produce glass gobs of high quality and high weight accuracy with high productivity. SOLUTION: A drive signal 1 to start driving of a transfer means 108 is delivered, by which a formed die is moved to a casting position. A signal indicating that the driving is completed is received and, when this signal is received, the drive signal 1 to start the driving of a lifting means for the formed die is delivered, by which the forming die is risen to receive the front end of molten glass and thereafter the forming die is lowered to receive the molten glass of a specified weight. The drive signal 1 is delivered at the time when a predetermined time elapses after the receipt of the signal indicating the delivery of the driving signal or the completion of the drive signal, by which the forming die receiving the glass gob is transferred and the empty formed die is transferred to the casting position.
