Description

Technical Field

[0001] The utility model belongs to the technical field of tire production and processing, and in particular relates to a top ring device for a tire building machine. Background Art

[0002] In the tire manufacturing process, the main operating steps in the first stage of the two-stage forming of the giant engineering radial tire are: finger plate positive wrapping - buckle wire ring - buckle ring plate and finger plate withdrawal - locking ring by locking ring device - other operations. The wire ring is fixed after being locked by the locking ring device, but after buckling the wire ring and before locking the wire ring, the wire ring is hung on the carcass by the adhesion between itself and the carcass cord and between the apex rubber attached to the wire ring and the carcass cord, and the wire ring is suspended in the air without any support. Since the mass of the wire ring of the giant engineering radial tire is very large, the wire ring will sag if it is fixed only by the adhesion between rubber; the carcass cord will generate a rebound force in the opposite direction after positive wrapping. After the finger plate is withdrawn, the carcass cord will drive the wire ring to move in the opposite direction of buckling the wire ring, so that the wire ring will be axially and radially skewed, which seriously affects the quality of the tire.
