Abstract
PURPOSE: To obtain an accurate sealing in a short space of time by removing bubble through an even spreading of an adhesive with a relative motion of intended matters made so as to allow the adhesive to wert the surface to be sealed and then halted for hardening thereof.
CONSTITUTION: A relative motion of intended matters 1 and 4 is made so as to allow an adhesive 14 to set the surface to be sealed and then, halted for hardening thereof. For example, a glass bulb is retained with a rotating member 3 with a vacuum chuck 2 while an exhaust tube 7 for a glass stem fitted with a leading-in wire 5 and a filament 6 is retained with a retaining member free to be rotated and braked. The open rim 13 of a bulb 1 and a skirt section 12 of the stem 4 are brought close to each other and the bulb alone is allowed to turn. In this manner, an unhardened paste-like epoxy resin adhesive is fed through a nozzle 15 to be applied evenly between the surfaces 12 and 13 to be sealed. Thereafter, with a synchronous rotation of the bulb 1 and stem 4, the portion to be sealed is heated with a burner 16 or the like and then, the adhesive is hardened to complete the sealing up.
