摘要： PURPOSE:To obtain homogeneous paper with hardly any variation in mass and difference between the front and the back sides by sensing the change in thickness of a stock on a wire with noncontact type displacement sensors and regulating the dehydrated state of the stock. CONSTITUTION:The thickness of a stock 4 on a wire 3 is measured by two noncontact type displacement sensors 7 and 7' mounted on a jig 6 horizontally held at a position at right angles relatively to the sheet forming direction 5. The one sensor 7 senses a distance 8 between the sensor and the surface of the stock and the other sensor 7' senses a distance 9 between the sensor and a dehydrating element 2. The thickness of the stock on the wire is obtained by subtracting the wire thickness from the difference between the distances 8 and 9.
