Problems solved by technology

[0006] As a result, since the inventory management of intermediate products requiring many tire components is required, the management of intermediate products becomes complicated, and the replacement of the winding frame on which the intermediate products are wound is replaced every time the size of the tire produced is changed. There are many operations, which hinders the improvement of productivity

Embodiment Construction

[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, the same constituent elements are denoted by the same reference numerals, and repeated explanations are omitted.

[0018] exist figure 1 , 2 Among them, 1 is a uniaxial extruder, 2 is a circular die installed on the extrusion port of the uniaxial extruder 1, 3 is a ventilator for air cooling the cylindrical film W extruded from the circular die 2, and 4 Reference numeral 5 denotes a roll body formed by winding a cylindrical film W into a roll, 5 denotes a building drum (tire molding machine), and W1 denotes a tire component. The tire component W1 is composed of a thermoplastic resin elastic material in which a rubber component is dispersed in a thermoplastic resin component, and is particularly suitably used as an inner liner arranged on the inner surface of a pneumatic tire.

Abstract

A method of feeding a tire structure member, where rolled-up objects, made by rolling up a hollow cylinder-like film into a roll-like shape, are formed by sizes depending on nominal diameters of tire rims, the hollow cylinder-like film formed of thermoplastic elastomer that is a blend of a thermoplastic resin and rubber. In forming a green tire, a hollow cylinder-like film, paid out from a rolled-up object in accordance with a nominal diameter of a rim of the green tire, is cut into a required width in accordance with a tire size to form a tire structure member, and the tire structure member is fed to a tire-forming machine.

Description

technical field [0001] The present invention relates to a supply method of tire components, and more specifically, to a method of supplying tire components which can improve productivity while facilitating the management of intermediate products of tire components in stock. Background technique [0002] Generally, a raw tire (green tire) is formed by supplying each tire constituent member to a building drum of a tire building machine, and laminating each tire constituent member sequentially on the forming drum. [0003] Tire components such as an inner liner and a carcass are usually formed by producing a long belt-shaped roll as an intermediate product of the tire component and cutting it to a predetermined length. Even if the tire components are used for tires having the same nominal value of the rim diameter, if the tire size (nominal value of section width and nominal value of aspect ratio) is different, the width dimension will also be different. Therefore, it is neces...
