The standard square sheet machine has been widely used. Its capability has been highly evaluation, as its good formation of handmade paper like the standard round type. But its sheet making area is small, 25 x 25cm, resulting in increased demand for larger paper sample. Based on the conventional paper making experience, we KRK have added this large size sheet machine to our inventory. Its machine configuration is the same as that of the standard square type. To produce well formed samples, it is designed focusing on good balance between components: specimen tank, pyramid-shaped drainage tank, filter plate and discharge device. This high quality and durable machine are provided with a pneumatic ball valve, enabling rapid drainage, and eliminating the potential of trouble due to fibers in white water, accumulated during long year operation. We also supply machines for processes after paper making, such as press, air dryer and rotary dryer.
