摘要： In a heating drawing, a base material glass plate is heated and softened in a heating furnace, and drawn to a desired thickness to form a glass strip. In the heating drawing, the base material glass plate is heated so that the base material glass plate has a U-shaped temperature distribution in a width direction. Such process can be realized through heating by a heating element which has a non-heating portion at a position opposite to a central portion of the base material glass plate in the width direction and a heating portion on both sides of the non-heating portion. Thus provided is a method of manufacturing a glass strip, the method includes heating and softening the base material glass plate, and drawing the base material glass plate to a desirable thickness to form a glass strip, and is capable of manufacturing a thin, rod-like glass strip with an excellent flatness.

摘要： Included are a reducing-heterogeneous-layer removing process of removing at least a part of a reducing heterogeneous layer in a surface of a plate glass manufactured through a float process, and a heating drawing process of heating and softening the plate glass from which at least the part of the reducing heterogeneous layer is removed in a heating furnace to draw the plate glass to a desirable thickness to form a glass strip. Thus provided is a method of manufacturing a glass strip capable of manufacturing a thin, rod-like glass strip with an excellent flatness even when a plate glass to be subjected to the heating drawing is a plate glass manufactured through the float process.

摘要： An optical fiber drawing furnace capable of the prevention of entry of an ambient gas into an inner space thereof both effectively and economically, provided with a lower gas introduction portion through which inert gas is introduced into the inner space of the optical fiber drawing furnace, a chamber separated by a lower partition, and a bottom cover. The lower partition is arranged immediately below the lower gas introduction portion and has a first hole through which the chamber and the inner space are communicated. The bottom cover has a second hole through which the chamber and the atmosphere are communicated. An optical fiber is passed through the first and second holes. A controller detects a differential pressure between a pressure P1 in the inner space and a pressure P2 in the chamber and controls the suction flow by a pump for evacuating the gas in the chamber to maintain P1>P2. The sizes of the first and second holes are defined as (L1/D1)
