Abstract
A flat drum capsule for tyre molding is shaped as a cylinder. The outer shape of the capsule is a segment-difference structure: diameter of the middle segment is larger than diameter of the two ends, and the inner surface is an isometric cylinder. The material of the whole capsule is composed of composite materials such as fiber cloth and a rubber material, etc. The whole capsule sleeves the flat drum and is connected and fixed through bolts. The middle segment is provided with vacuum connecting holes corresponding to air faucets on the flat drum. When the rubber material fits the capsule and is adsorbed through vacuum air faucets to closely fit the outer surface of the capsule. After fitting of the rubber material, pressure within and outside the rubber material is balanced by blowing air through the vacuum air faucets and then the rubber material is easy to take off from the flat drum capsule. Due to the segment-difference structure, bubbles at the middle segment are easy to discharge out of the two ends during rolling. Thus, bubbles at rubber material fitting ends are solved, seamless fitting is realized, and fitting precision and stability are enhanced. By the use of the seamless capsule, the rubber material has no radial indentation during flat drum fitting, and local tire wirecord fabric's internal drawing caused by inconsistent force applied on a flat drum support block when supported is effectively avoided.
