METHOD FOR IMPROVING PRODUCTION PROCESS FOR WIDE-BASE TRUCK RADIAL TIRE
The present patent provides a method for improving the construction process of a wide-base radial truck tire, and the improvement of the tire construction process is realized by the design of carcass ply, the tire belt drum and the tire semi-finished components. The patent solves the problem of carcass bending, and provides theoretical guidance and technical support for improving the performance of wide-angle radial tires. The design method of the belt drum of the tire molding machine effectively controls the cords elongation of the belt. In addition, the problem of uneven force in the cords of the belt is eliminated, which dispels the abnormal flow of the wide-base tire shoulder rubber to the center of the crown during the shaping process, thus improving the durability and operability of the tire. The proposed semi-finished components design method in this patent can accurately design the tire semi-finished parts material distribution map, significantly improve the finished tire and the theoretical design of tire material distribution consistency, thus reducing tire development cycle and development costs.
Method for manufacturing motorcycle tire
A method for manufacturing a motorcycle tire includes forming a cylindrical raw tire body including a carcass body including a carcass ply and bead cores on the carcass ply, and forming a cylindrical belt ply wound in a cylindrical shape. The forming of the belt ply includes filling the tire body to expand to first expanded phase, winding a sheet-type belt ply by extending the sheet-type belt ply on bell rings to form the cylindrical belt ply with inner surface bonded to the apex of the tire body, filling the tire body to expand the apex of the tire body along with the belt ply to second expanded phase, increasing diameter of an expandable profile deck to expand the apex of the tire body along with the belt ply to third expanded phase, and winding down edges of the belt ply to bond the belt ply to the tire body.
TIRE MANUFACTURING METHOD AND MANUFACTURING SYSTEM
Provided is a method of manufacturing a tire and a system for manufacturing a tire. A forming drum body to which a tire component is bonded after completion of a forming operation in an operation station is temporarily placed in a placement apparatus. While the forming drum body is temporarily placed in the placement apparatus, the mass of the green tire is inspected by a mass meter as a predetermined quality of a green tire formed by the tire component bonded to the forming drum body during forming or after completion of the forming, and the profile shape of the green tire is inspected by a profile sensor.
Working station for deposition of elementary semifinished products for building tyres
A working station for deposition of elementary semifinished products for building tyres is, the working station includes an anthropomorphic robotized arm for moving an output end effector, a building drum, a feeding apparatus and a control apparatus. The control apparatus is configured to calculate, in a drive interval, a pulse with modulation (PWM) profile for a speed parameter and controlling the output end effector as a function of the PWM.
