摘要： PROBLEM TO BE SOLVED: To provide a method for supplying a color coating glass current by which the glass is supplied for a long time at an extremely slow lifting ratio including zero without the color coating glass supply spout being stuck or broken and to furnish its device. SOLUTION: This device is provided with a first orifice 22 for receiving a core glass from a first glass source 12 and forms a color coating glass current having an inner core glass surrounded by an outer color coating glass. The color coating glass supply means has an exposed surface area, a spout 36 for receiving the color coating glass in the pool and a spout tube 38 arranged in the spout 36, and the spout tube occupies a second surface area on the pool surface. The ratio of the second surface area to the first surface area is controlled to >=15% to maintain the glass pool temp. in a low lifting ratio.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of devitrification and to enable the outflow of fused glass having the flow rate and viscosity adequate for molding by enclosing the front end of a pipe with a cylindrical cover opened at its bottom end and disposing a ring burner in proximity to the circumference of the cover. SOLUTION: The fused glass flow 17' controlled in the flow rate and the viscosity is made to flow out of an outflow port 19. At this time, a gaseous mixture composed of oxygen and butane is supplied from gas supply pipes 3a, 3b to the ruing burner 2 to burn the gas and to heat the cover 1 and collar- like members 7a, 7b from multiple directions. The oxygen and the butane are preferably mixed and supplied while the respective flow rates are controlled by a flow meter and a flow rate control valve. Cooling water is supplied from a cooling water supply pipe 5 to a water cooling pipe 4 clearing the burning of the gas and the cooling water is discharged from a cooling water discharge pipe 6 to cool the ring burner 2 by the water cooling pipe 4, by which the backfire by the overheating of the ring burner is prevented.

摘要： PURPOSE:To obtain a device for heating and cutting a glass to heat the tip part of the glass by an independent heating means. CONSTITUTION:The 3rd heater 5 surrounding the surface of the tip 6 of molten glass flow flowing out from a crucible 1 of the device for heating and cutting glass and to heat the tip part 6 of the glass is provided. The heater 5 is fixed at the tip part of a rotary arm 7 and is freely movable in close to and apart from the tip part 6.

摘要： PROBLEM TO BE SOLVED: To provide a method by which the hydrostatic head pressure applied to a core glass stream can be increased without adversely affecting the core glass supply and heating of the core glass stream can strictly be controlled so that the optimum performance and minimum leakage are obtained and also to provide the device for the method. SOLUTION: This device has a reservoir 14 that is provided with at least one lower opening (first opening) 16 having a first diameter and used for receiving and holding core glass an orifice ring 24 that is placed below the reservoir 14 and provided with at least one opening which has a second diameter smaller than the first diameter and is formed so as to match the first opening 16 and also, of which a first orifice 22 consists, and further, a collar 44 that has a uniform inner diameter equal to the first diameter and extends from the first opening 16 to the orifice ring 24. Thus, the static pressure applied to the core glass flowing from the reservoir 14 through the first orifice 22, can be increased.
