Abstract
A method is provided for checking a pickup load cell in a tablet-making machine which detects the compressive force applied to a tablet being formed. According to the method, a dummy tablet-forming die formed on a support block is inserted into a selected one of the die-receiving holes formed in a rotary table in place of a real die. A reference load cell is put on the support block, and the reference load cell and the support block are sandwitched between an upper pressure rod in place of an upper punch and a lower pressure rod in place of a lower punch. Measurements are made by both the pickup load cell and the reference load cell as the reference load cell is compressed between a pair of pressure rollers, and the value of the compressive force detected by the pickup load cell is corrected in accordance with the value of the compressive force detected by the reference load cell.
