Application: Roll press device and method of producing laminate structure (Patent ID: US20230420635A1)
The patent filed by Murata Manufacturing Co Ltd. describes a roll press device for pressing a laminate structure using a pair of press rolls and an auxiliary roll positioned either upstream or downstream of the press rolls. The auxiliary roll's contact surface is positioned above or below a virtual plane that the laminate structure includes when passing between the press rolls. The device is designed to accommodate different configurations of the laminate structure, ensuring efficient pressing.
Furthermore, the patent outlines specific claims related to the angle of the auxiliary roll's contact surface, the structure of the laminate including substrate, first and second layers, and the density values within the first layer. The method for producing the laminate structure involves pressing it between the press rolls, considering the optimal incline angle of the end surface of the third end portion, and maintaining specific volume density ratios within the first layer. The roll press device and method aim to enhance the quality and efficiency of producing laminate structures with varying layer configurations.
