Apparatus for forming tires utilizing rotary base

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...
