Abstract

PURPOSE:To reduce the deviation of distances between ends of glass bulbs and reduce required parts and works by separating the operation of winding drums from the operation of winding chuck which holds ends of a glass bulb formed in an annulus. CONSTITUTION:When a glass bulb 3 is wound on the periphery of a winding drum 11, links 21, 22 are opened, the winding drums 11, 11 are moved in the drum axis direction to the position at which the surface of sleeves 15, 15 touch the surface of stoppers 22, 22 while a winding chuck 12 is maintained closed, and then the winding 11, 11 are separated from each other. Thus, the annulus formed glass bulb 3 is maintained being held with the chuck 12 at the wounded end, and the winding drums 11, 11 are maintained separated from the glass bulb 3, the inside and outside of the bulb are cooled evenly, tensile stress is not generated, both ends of a glass bulb are maintained at the held position, and the deviation of the distance between both ends is prevented.
