With a total of 2 patents to his name, Maekawa's innovations have the potential to enhance the efficiency and quality of tire production.

Latest Patents

Maekawa's latest patents include a method of manufacturing a radial tire for construction vehicles. This method involves forming a cylindrical band using a carcass layer made of steel cords. A shape-retaining layer, composed of organic fiber cords, is then wrapped around the carcass layer, ensuring that the organic fibers cross the steel cords. This innovative approach allows for the production of radial tires with excellent uniformity, eliminating the need for auxiliary shape-retaining apparatuses.

Another significant patent is a method of producing a radial tire for construction vehicles that drastically reduces facility costs. In this process, a first green tire is formed in a molding machine and subsequently removed. A vulcanizer bladder unit is then installed, inflating the tire before it is placed back into the molding machine. The outer periphery of the tire is then fitted with belts and tread rubber, culminating in the creation of a completed green tire, which is finally assembled in a vulcanizing mold for vulcanization.
