Frit coating method, a frit coating apparatus, a sealing apparatus, and a sealing method for a flat-type cathode-ray tube

A frit coating apparatus comprising:

• a frit supplying means for supplying frit;
• a roller-type coating means for supplying said frit to an object to be coated;
• and
• a moving means for moving said object to be coated. in a close relation to said roller-type coating means.

A frit coating apparatus comprising a

• frit supplying means for supplying frit;
• a roller-type coating means for supplying said
• frit to an object to be coated, and
• a moving means for moving said object to be coated in a close relation to said roller-type coating means, wherein
• said roller-type coating means has a concave and convex surface.

A sealing apparatus for a flat-type cathode-ray tube comprising:

• a frame for properly positioning a combined assembly in which joint surfaces of a front panel, a screen panel and a funnel are butted with each other by frits, and
• a sealing jig which is comprised of a holding means for holding a front panel and a screen panel such that joint surfaces of said front panel and said screen panel are butted with each other by frits,
• said holding means being provided with a first resilient member which is urged against the outer surface of said front panel and a second resilient member which is urged against the outer surface of said screen panel,
• a portion in which said first resilient member comes in contact with said front panel being formed of a member whose hardness is selected to be less than that of panel glass.
