Abstract:
1. A method of producing a preform for precision press molding, wherein a plurality of support members which receive and support molten glass is provided, the method comprising the steps of: forming a molten glass body by either receiving and cutting the molten glass, being flowed continuously from a discharge nozzle, by a support member, or by allowing the molten glass to fall from the discharge nozzle and receiving the molten glass by a support member; displacing the support member which has received the molten glass body to near a mold disposed at a location that is not beneath the discharge nozzle, while increasing the viscosity of the molten glass body on the support member, while at the same time displacing another support member to beneath the discharge nozzle to form another molten glass body; and respectively transferring the molten glass bodies received by the support members from the support members to the mold by way of at least one glass body transfer auxiliary member provided at a position separate from the support members, wherein the number of glass body transfer auxiliary members is smaller than the number of support members.
