Abstract:
An inner circumferential film forming step includes an inner circumference coating step of forming a coating film on an inner surface of a glass pipe. The inner circumferential film forming step includes a coating material discharging step of discharging a coating material remaining in the glass pipe by inclining the glass pipe with the circumferential position of the glass pipe fixed. The inner circumferential film forming step includes a drying step of drying the coating film formed on the inner surface of the glass pipe. An outer circumferential film forming step includes an outer circumference coating step in which the glass pipe is rotated about a center axis as a rotation axis to apply the coating material on the outer surface to thereby form the coating film. The outer circumferential film forming step includes a lifting step in which the glass pipe is lifted from the coating material while inclining the glass pipe with the circumferential position of the glass pipe fixed, and a drying step of drying the coating film formed on the outer surface of the glass pipe.
