Engineering meridian tyre body cord fabric/belt bundle layer combining type cutting technique

Abstract

The invention relates to an engineering radial tire carcass cord / belt combined cutting method, which belongs to the technical field of tire manufacturing. After the roll is guided, it is cut by the cutting machine through the traction device for fixed-length delivery. After cutting, it is transferred to the belt joint device through the conveyor belt for automatic jointing. The belt layer after the joint is delivered to the After the automatic film sticking device sticks the film and the rubber edge, it is passed to the coiling device for coiling; after the material roll is unwound, it passes through the traction device for fixed-length delivery, and then it is cut by the same cutting machine, and after cutting, it passes through the conveyor belt Transfer to the carcass ply joint device for automatic jointing, and the jointed carcass cord is transferred to the automatic film application device through the storage material and the conveyor belt for film and rubber wrapping, and then transferred to the coiling device for coiling. The equipment investment is reduced, and the cutting accuracy and process requirements of the carcass ply and the belt are guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of tire manufacturing, in particular to a process method for cutting the carcass ply and the belt of a giant engineering radial tire in the form of a carcass ply / belt combination. Background technique [0002] As we all know, the tires used for construction vehicles are referred to as engineering tires. Domestic and foreign manufacturers mainly engage in engineering tires with bias structures. In recent years, they have developed and produced all-steel engineering radial tires. The engineering radial tires currently produced in China are under 35 inches. For small engineering radial tires, the carcass cords and belts used to produce tires of this specification are all produced by independent conventional cutting machines. However, for the carcass ply (maximum width 5.5 meters, thickness 1.5-8mm) and belt layer (maximum width 1400mm, thickness 1.5-8mm) of giant engineering radial tires over 49 inches, the cutting ...
