  • Flow speed control plate
    Patent number: 10836075
    Abstract: A flow speed control plate is provided for use in combination with a die for forming a monolith. The flow speed control plate includes: a base plate having both a clay supply surface and a clay outflow surface that is to be superposed on a clay inflow surface of the die; clay flow holes which each penetrate the base plate and through which the clay flows from the clay supply surface to the clay outflow surface; and a positioning mechanism provided to position the flow speed control plate with respect to the die so that each of the clay flow holes of the flow speed control plate has its central axis arranged coaxially with a central axis of a corresponding one of clay inflow holes of the die. Moreover, a diameter of the clay flow holes is set to be smaller than a diameter of the corresponding clay inflow holes.
