Latest Patents

One of Tominaga's latest patents is a metal plate joining method and apparatus. This invention features a pair of upper and lower pressure rollers that are tilted in opposite directions relative to a straight line perpendicular to the welding line of a joint portion. The rollers are driven by electric motors, allowing them to roll the joint portion effectively. This design smooths out steps at the joint and reduces step gradients, ensuring a high degree of joint strength and preventing interfolding into the base material of the metal plates.

Another notable patent is for cold rolled material manufacturing equipment and a cold rolling method. This equipment includes an unwinding device for hot rolled coils, a joining device for connecting coil ends, and a rolling mill for continuous rolling. It also features a strip storage device, a cutting device, and a winding device, all designed to optimize the manufacturing process. The rolling speed control device ensures that the joining speed is lower than the steady rolling speed, enhancing the overall efficiency of the operation.
