Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0025] As an embodiment of the present invention, in order to manufacture tires of the most common shape, six molding machines 30 are arranged radially on the rotating base 32, and one conveying pressure ring 33 and four extruding rings are arranged outside the rotating base 32. Machine 1, 2, 3, 4.

[0026] FIG. 5 is a plan view showing the structure of the present invention, and FIG. 6 is a front view showing the structure of the present invention.

[0027] As shown in Fig. 5 and Fig. 6, 6 forming machines 30 are arranged radially on the top of the circular rotating base 32, and a conveying pressure ring 33 and 4 extruders 1, 2, 1 and 2 are arranged around the rotating base 32 3, 4, and correspond to the molding machines 30 formed on the upper part of the rotating base 32 respectively.

[0028] The spare tire 19 is installed on the molding machine 30 at the p...

Abstract

An apparatus is invented for forming a tire tread on the surface of a prototype tire that is pre-fabricated during the tire manufacturing processes. The apparatus for forming the tire comprises six forming devices disposed above the circular rotary base for securing the prototype tire, a transporting compression ring disposed around the rotary base for supplying and compressing an iron core belt onto the prototype tire of the forming device, and a first extruder, a second extruder, a third extruder, and a fourth extruder for extruding a ribbon-shaped rubber band to form a tire tread on the surface of the prototype tire. Accordingly, by constructing a plurality of extruders around the circular rotary base, the installation space can be smaller than the conventional prototype tire forming apparatus, the device fabricating cost can be reduced, and various shaped tires can be fabricated.

Description

technical field [0001] The present invention relates to a tire building machine that molds a tire tread that is in direct contact with the ground onto a pre-manufactured spare tire during a plurality of tire manufacturing processes. Background technique [0002] As shown in Fig. 2, a general tire tread 10 is composed of a cap layer 11, an undertread 12, a tread 13, and a reinforcement portion 14. tire. [0003] Conventional devices for forming tire treads on spare tires have very complex structures and are large-scale equipment, so they have the following disadvantages: they require high equipment investment costs, require a wide installation space, and are difficult to adjust according to the design and size of the tires. Changes make design changes and equipment changes. [0004] A description of a conventional apparatus for forming a tread on a spare tire follows. [0005] FIG. 1 is a configuration diagram of a tire tread manufacturing device of a conventional tire bui...
